Water Forum Agreement 2050
February 2026 111
To that end, the Water Forum will apply methodologies to help inform its full range of implementation activities, guiding our work to meaningfully reflect the Water Forum’s commitment to the Sacramento region. While specific approaches will vary from program to program, implementation activities should consider the following issues:
• How outreach is being carried out to ensure people from historically underrepresented groups are made aware of Water Forum activities (e.g., tribes and economically disadvantaged communities, among others)
• How and when input is being gathered to help overcome barriers to meaningful participation (e.g., time of day, location, unseen costs, etc.) • How the Water Forum can evaluate, (1) how its actions are perceived and/or impact groups across the region, and (2) how the legacy of non-participation by historically underrepresented groups may be improved through Water Forum implementation when appropriate
In addition to these important yet more general practices, the Water Forum and its members participate in various initiatives that can help foster broad participation within all communities affected by the coequal objectives. These efforts can include access to our region’s natural resources, education about the LAR, and support for the affordability of our drinking water. These efforts can be continued and strengthened under the WF2050 framework. • American River Corridor Health and Access – The Water Forum recognizes that its habitat enhancement work along the American River corridor, in furtherance of the coequal objectives, has the potential to affect historically underrepresented communities. The Water Forum is aware of and will continue to work to understand these conditions, from fire risk and waste management, to safety, pollution, river access and use, and other human dimensions of resource management. Recognizing these complexities and with the leadership of the Public Caucus, the Water Forum will work to draw in speakers and members able to bring this vantage point to Water Forum discussions. • Water Affordability – The Water Forum recognizes there is a potential nexus between its members’ commitments and water affordability. Considering this, Water Forum members commit to fostering an ongoing series of dialogues and joint learning sessions as part of the implementation of WF2050 to better understand this connection, and, as appropriate, identify relevant best practices that have the potential to contribute to achieving the Water Forum’s coequal objectives while accounting for affordability concerns. Signatories are committed to exploring this topic while acknowledging that rate-setting rests within the purview of each water purveyor’s governing body and applicable laws. • Education – Under the leadership of the Public Caucus, the Water Forum will engage with underrepresented communities to, (1) understand how the coequal objectives resonate with, address and/or impact these communities’ needs and priorities, (2) improve public

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 112
participation processes, and (3) identify opportunities to implement WF2050 in a way that accounts for people having different access to resources due to systemic inequities. This will focus primarily on Water Forum-led activities, but can also include members sharing guidance with one another on strategies they can undertake to deepen their public participation processes.

The Water Forum recognizes that its work to meet the interests of the broader community is an ongoing effort and welcomes feedback on how it can engage more effectively with communities across the region as it pursues its coequal objectives.

FUNDING
The Water Forum’s governance, finance, and administration will be transparent and collaborative in nature. The operation and funding of the Water Forum require a significant commitment of time and money by interested parties to promote and carry out stewardship of our watershed’s resources. The administration of the Water Forum’s various initiatives, along with its large group of signatories and interested parties, requires a dedicated and consistent effort to make progress toward achieving the coequal objectives.

Guiding Principles
The principles outlined below shape the Water Forum’s approach to budgeting and funding its activities, and are intended to create a foundation for equitable and sustainable funding and budgeting throughout the life of this agreement.

1. Finance Mechanisms
Effective Water Forum governance must provide a clear and reliable financial mechanism to generate the necessary funding, as well as a transparent and inclusive process for identifying and confirming funding sources.

2. Diverse Funding Sources
Water Forum activities are to be funded through a mix of water purveyor contributions, state and/or federal grants, and in-kind contributions of non-monetary support for Water Forum initiatives, including advocacy, public outreach, in-kind contributions of time, etc. The Water Forum will continue to pursue diverse forms of funding and is open to funding contributions from all caucuses.

3. Commitment to Affordability and Cost-Effectiveness of Actions When considering program areas and priorities, the Water Forum is committed to understanding the cost-effectiveness and affordability of its actions. The Water Forum further acknowledges that while programs and activities are funded through a range of sources, they are primarily funded through local ratepayers, and we have a responsibility to provide clear benefits to those ratepayers and the broader public.

4. Financially Viable and Effective
The Water Forum strives to establish a budget and funding mechanism that balances the meaningful and ongoing pursuit of its coequal objectives with the limited financial capacity of its funding members. To that end, the Plenary sets annual priorities that are consistent with both the Water Forum's objectives and available budget resources.

5. Differential Abilities to Pay
The Water Forum recognizes that its members, both within and across caucuses, have varying abilities to contribute to Water Forum funding. The Water Forum budget and funding allocation approach is structured to account for these differences. All members are expected to contribute,

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 114
at a minimum, substantial in-kind effort through participation in a range of committees, Plenary meetings, and activities.

6. Ongoing Budgetary Review
Each year, the Water Forum shall undertake a thorough review of progress to date and update its annual work plan based on funding needs and the expected contributions of funders. Any increase or decrease to the annual budget requires a consensus among all caucuses and agreement by those agencies providing Water Forum funding.

7. Long-term Budgetary Planning
The Water Forum recognizes that pursuing its coequal objectives requires longer-term budgeting and financing commitments. To that end, while Water Forum budgets must be approved annually by both its funders and the Plenary, the Water Forum will undertake longer-term budgetary planning to provide greater clarity and certainty to both funders and the Water Forum’s programmatic long-range planning. It will also consider base funding from sources other than ratepayers.

8. Augmenting Water Forum Member Funding
The Water Forum strives to augment annual contributions from its funders with grant funding from federal, state, and other sources that will further contribute toward its mission to advance the coequal objectives. Such grant applications, prepared by the Water Forum, must be approved by resolution of the Sacramento City Council. The City of Sacramento would be the formal grant applicant.

9. Importance of Maintaining a Reserve Fund
The Water Forum recognizes that costs and funding may fluctuate from year to year. To maintain a consistent program across uneven funding years, the Water Forum is committed to building and maintaining a reserve fund equal to 120 days of working capital. The Water Forum reserve fund will be managed in accordance with relevant policies and best practices per the City of Sacramento.

10. Program Fund Accounts
The Water Forum’s program funds include the WFSE, HME, and grants, keeping outside funding separate from Water Forum member contributions. The WFSE and HME fund expenses are tracked separately to maintain budgetary transparency for these two distinct functions. Similarly, outside grant funds or potential Healthy Rivers and Landscape Program funds will also be separately accounted for and budgeted. Additional funds accounting approaches may be applied as funding sources / other requirements dictate. The HME fund shall have a cap; if and when that cap is reached, funders will not be assessed additional HME funds until the balance drops below the cap level.

03/10/2026 Item No.11.

Water Forum Agreement 2050

Program Elements

1. Water Forum Budget
As an entity within the City of Sacramento’s administration with a July through June fiscal year, the Water Forum budget also operates on a July through June fiscal year. The Water Forum budget will be approved by the Plenary as described below, and the associated funding contributions are expected to be approved by the funding agency governing boards and councils no later than May.

Below is a description of the process for developing and approving annual budgets as part of the WF2050 Agreement.

Budget Description
The annual budget, prepared by the Executive Director, will include, but not be limited to, the following elements:
• Clear linkages to annual and multi-year work plans
• Delineation of costs associated with staff, consultants, direct expenses, contingencies, etc. • Status of the Water Forum reserve fund
• A report on prior year expenditures (actuals)
• A report on the status of local, state, and federal grants • Highlight budget items tied to Interagency agreements or contracts between the Water Forum and signatories
The budget is to be developed with the assistance of the City of Sacramento Department of Utilities’ finance staff, consistent with the Water Forum-Department of Utilities MOU (refer to Appendix 10: Water Forum and Department of Utilities MOU).

Water Forum Budget Process and Schedule
The Executive Director will annually develop a proposed budget, which the Coordinating Committee will review and approve. As part of its review, the Coordinating Committee will engage with Water Forum funders (water purveyors with PSAs, implementing agencies, and flat fee agencies) to ensure the proposed budget and work plan are consistent with funders’ anticipated contributions. A final proposed budget will be shared with and must ultimately be approved by the Plenary.

The Water Forum annual budget will be developed each year using the following fiscal year (July 1 to June 30) schedule:
• September – November: Internal budget development for future fiscal year by Water Forum staff based on review of operating budget and actual expenditures, Water Forum

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 116
priorities (set by the Plenary), annual work plan including upcoming project costs and staffing needs, reserve fund status, and anticipated revenue (funder contributions and grants). Executive Director reviews first and subsequent drafts of the future fiscal year budget with the Coordinating Committee.
• November – December: Executive Director meets with the Water Caucus (with expanded participation, as needed, to bring in any non-Water Caucus funders) to review and confirm consistency with funders’ funding abilities and commitments. The Executive Director collaborates with the Coordinating Committee (in consultation with interested funders) to resolve any outstanding funding and budgetary issues before submitting the budget to the Plenary for consideration and approval.
• January – February: Executive Director presents proposed draft for future fiscal year budget to the Plenary for its review and approval. This budget is accompanied by a memo that details the proposed budget, expenses, and the status of the reserve fund. Member agency contributions are calculated in January to allow for inclusion in annual member agency budgeting processes. Plenary identifies if there is any opposition to proceeding with the budget. As needed, the Executive Director, in consultation with the Coordinating Committee and interested funding members, revises the budget based on Plenary discussions and direction.
• February – May: Interagency funding agreements are signed, with final approval from the City of Sacramento Council for the upcoming fiscal year.

Budget Oversight Process
The Water Forum will establish a transparent budget oversight process, including the following reports, to foster effective use and tracking of Water Forum spending:
• August: Publish an annual implementation report card. Review the prior year's accomplishments and identify any uncompleted priorities with the Plenary. • August -September: Provide a standard budget report (spreadsheet) to the Coordinating Committee detailing prior fiscal year actual expenditures and remaining balance in reserve funds.
• October: Provide a standard budget report (spreadsheet) to the Coordinating Committee on the first quarter (July-September) actuals.
• January: Provide a standard budget report (spreadsheet) to the Coordinating Committee on second quarter (October-December) actuals.
• April: Provide a standard budget report (spreadsheet) to the Coordinating Committee on the third quarter (January-March) actuals.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 117
Prior to completion of the first year following the signing of WF2050, the Water Forum shall undertake a careful review of progress to date and shall revise the work plan considering existing circumstances. The annual budget and contributions may be revised at that time. Any increase or decrease to the first-year budget would require a consensus among all interest groups and agreement by funding agencies.

Use of Consultants
Consultants shall be used only as needed. Identification and approval of actual expenditures for specific consultant contracts shall be part of the Water Forum budget process. If consultant contract funds or funds allocated for consultant contracts in a given fiscal year are not spent prior to the end of that year or encumbered for future expenditure, the Water Forum shall modify the following year’s budget appropriately. To the extent that there is a need for consultant services not anticipated in the annual budget, such services can be allowed, provided there is an adequate budget (e.g., savings from another line item) and with the concurrence of the Coordinating Committee.

Reserve Fund
To ensure the Water Forum’s ongoing fiscally sound financial management and to adequately provide for unforeseen circumstances such as economic uncertainties, loss of significant revenue sources, grant match requirements, and grant monitoring as required, a Reserve Fund will be established with a target level equivalent to 120 days of working capital.

Budgets: Year 1 Budget and 5-year Look Ahead
To estimate the actual cost of the Water Forum’s work and foster long-term planning by its staff, members, and funders, the Water Forum is committed to producing a five-year look-ahead as part of its Five-Year Status Report. While the look-ahead is non-binding, members and funders will use these projections to identify and secure the necessary resources and shape the work of the Water Forum. The initial five-year look-ahead (2025-2030) is provided in Appendix 11. Fiscal
Year 2025-2026 budget components include proposed expenditures, a summary of projected funding sources, the HME Cost Share Projection, and the WFSE Cost Share. The Fiscal Year 2025- 2026 budget totaled $1,973,140 and is included in Appendix 11. All signatories have reviewed and agreed to this five-year look-ahead and associated budget.

2. Water Forum Funding
As part of their commitment to investing in a reliable water supply and a healthy LAR ecosystem, Water Forum member water purveyors and other funders voluntarily enter into an annual funding agreement that stipulates funding levels for the Water Forum, based on the negotiated Cost Allocation Method. This Cost Allocation Method is included as Appendix 12 and describes the funding allocation methodology in detail.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 118
Description of Funding Methodology and Other Sources
The Water Forum will draw on a range of sources to fund its annual budget. These sources include both member funding and resources provided by outside entities. It also includes both direct funding and in-kind support.

The funding allocation methodology intends to equitably share the costs of the Water Forum programs in furtherance of the coequal objectives. The current (2025) version of the cost allocation model is included as Appendix 12. This model will be updated at five-year intervals and will be subject to approval solely by the funding agencies listed in the model. It should be noted that this cost allocation assumes that all the purveyors identified in Table 2 in Appendix 12 will sign WF2050. If fewer funders sign WF2050, the percentages of the costs allocated to the other funders that do sign will increase.

Below is an overview of the agreed-upon funding sources and cost-allocation methodologies. • Purveyor Specific Agreements: Purveyors with PSAs provide funding based on the formula described in the cost allocation model (see Appendix 12), which was developed and unanimously agreed to by the purveyors, and as reflected in the annual funding agreement.
• Implementing agencies: Implementing agencies provide funding based on a set-fee model. These fees are set by mutual agreement between the implementing agency and the Water Forum and will be included in the Water Forum's budgets as agreements are made. Sacramento County, SMUD, EDWA, and SAFCA have contributed in this manner historically and are expected to continue doing so.
• Grants: The Water Forum receives extensive grant funding from federal, state, and other sources to support its work on the ARCH Program Area and may include other Program Areas in the future. The total grant funding varies from year to year and is outlined in the annual budget.
• In-Kind Donations: Significant resources are donated on behalf of Water Forum member organizations through the participation of their staff and members in various Water Forum activities and committees. In-kind donations are not reflected in the budget or funding allocation.

Except for grant funding that is earmarked for specific projects and purposes, all other funding provided to the Water Forum is collected as a general contribution. Funding is pooled across all these sources and then allocated to either the WFSE or the HME program based on the annual budget need, or to the Reserve Fund.

The process to amend the funding structure described above will follow the “Changed Conditions and Amendments to the Agreement” section outlined elsewhere in this document.

February 2026 119

3. Five-Year Review
As described elsewhere in this agreement, the Water Forum will comprehensively review progress made toward achieving the coequal objectives every five years. The results of this review will assist in the development of the next five-year plan, revising the annual work plan, and adjusting the current budget and activities to reflect successes and failures revealed by the review.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 120

ADMINISTRATION
Guiding Principles

1. Authority and Accountability
Water Forum governance should clearly articulate lines of authority and accountability among all parties to the Agreement. This accountability is intended to cover all aspects of the Water Forum work, including but not limited to: members to members; members and staff to one another; members and staff to the Water Forum mission and agreed-upon actions and priorities; and the Water Forum to the affected public.

2. Tracking Progress
Understanding, tracking, and reporting on the Water Forum's progress are essential to supporting the coequal objectives, as well as fostering thoughtful consideration of any necessary changes in its work and approach throughout the life of the Agreement. To that end, Water Forum governance should include clear metrics, benchmarks, and an agreed-upon process to ensure that Water Forum members and staff can track and, as needed, adapt its work related to the following:
• Water Forum-led projects and actions are intended to support Water Forum’s coequal objectives.
• Water Forum member-led projects are intended to support the Water Forum’s coequal objectives.
• A comprehensive understanding of both river health and water supply reliability Program Elements

1. Administrative Structure
The Water Forum will continue to be administered under the auspices of the City of Sacramento.

Staff will be either employees or contractors of the City of Sacramento, and all administrative responsibilities related to such employees or contractors will continue to be handled by the City.

This arrangement will:
• Ensure continuity between WF2050 and the priorities of the Water Forum • Preserve existing technical expertise
• Avoid creating another redundant government entity
WF2050 is made binding and enforceable through the execution of three agreements: the MOU for the Water Forum 2050 Agreement (this document, signed by all entities choosing to be Water Forum members); the annual Funding Agreements (which, consistent with the funding principles set forth above, are executed by the entities making payments to support the work of the Water Forum); and the Interagency Agreement for the Administration and Management of the Water

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 121
Forum (also signed by funding members, see Appendix 13). Together, these agreements will contain provisions to continue the Water Forum organization. All parties that sign the MOU will become full participants in the Water Forum. It is important to note that:
• All signatories to WF2050 will have equal standing in the Water Forum, regardless of whether they are a public agency, an investor-owned utility, or a community interest or advocacy organization.
• Although Water Forum staff will be employees or contractors of the City of Sacramento, the WF2050 signatories will provide overall policy direction for the work of staff.

2. Changed Conditions and Amendments to the Agreement
No individual Water Forum member or staff has independent authority to alter WF2050. At the same time, the Water Forum must be able to respond to the changing conditions or other unforeseen circumstances that will arise over the next several decades. WF2050 may be amended only by all signatories employing the same interest-based collaborative process used to negotiate the original WF2050. The Water Forum staff will facilitate and coordinate such negotiations should they prove necessary. Changes to WF2050 are the purview of the Plenary unless the Plenary decides they need to be referred to signatory members’ boards for formal confirmation.

Term of the Agreement
The original WFA, adopted in 2000, was set to expire after a 30-year term. In 2020, then Water Forum Executive Director Tom Gohring initiated a renegotiation of the WFA well in advance of the expiration date, recognizing that the original agreement had taken seven years to negotiate and that regulatory, policy, and physical conditions had substantially changed over the past 20 years.

While the renegotiation of the WFA is expected to be completed prior to the original expiration date and in less time than the original negotiations, it is recognized that, due to the nature of the agreement and the complexity of the issues, members should anticipate and plan for future renegotiations.

Therefore, given the complexity of issues and anticipated climate change, WF2050 is to be reviewed through an assessment of key indicators in the Five-Year Status Report, including data from UWMPs and GSPs, on a 5-year basis, with a renegotiation term of 25 years.

The anticipated timeline of review and renegotiation is as follows for the period of 2025-2050:
• 2025: Signing of the New Agreement, WF2050. Publish updated Annual Work Plan that lays out programmatic and budgetary priorities for the coming year, as well as a look-ahead for the FY 25/26-30/31 period.
• 2030: Publish Five-Year Status Report. Review progress on implementation of program elements; develop updated Annual Work Plan that lays out programmatic and budgetary

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 122
priorities for the coming year, as well as a look-ahead to cover the next 5-year period (FY 30/31-35/36) for Plenary approval.
• 2035: Publish Five-Year Status Report. Review progress on implementation of program elements; develop revised Annual Work Plan that lays out programmatic and budgetary priorities for the coming year, as well as a look-ahead for the next 5-year period (FY 35/36- 40/41) for Plenary approval.
• 2040: Publish Five-Year Status Report. Review progress on implementation of program elements; develop revised Annual Work Plan that lays out programmatic and budgetary priorities for the coming year, as well as a look-ahead for the next 5-year period (FY 40/41- 45/46) for Plenary approval.
• 2045-2050: Publish Five-Year Status Report. Initiate review and renegotiation of WF2050 to coincide with a 25-year renewal period. Provide a 5-year window to complete, with the anticipated new agreement to be approved no later than 2050. This 5-year window can be automatically extended with the concurrence of the Plenary, provided that negotiations are deemed productive and are on a path towards a successful conclusion.

Request for Renegotiation
Renegotiation can be requested outside of the scheduled timeframe. Any proposal to renegotiate WF2050 would be considered in the context of the Water Forum’s coequal objectives. Specific engagement processes for renegotiating WF2050 should be developed through a transparent and collaborative process.

Request for Amendment
Amendments to WF2050 can be requested outside of the scheduled timeframe. Any proposal to amend WF2050 would be considered in the context of the Water Forum’s coequal objectives.

Specific engagement processes for amending WF2050 should be consistent with the collaborative decision-making process that was used in the development of WF2050.

Process for Renegotiation or Amendment Requests
The mechanism to request consideration of amendments is as follows:
• Any signatory, caucus, or Executive Director can make a formal request for renegotiation of some terms. The request must include a rationale stating the changed conditions warranting consideration and should include proposed amendment concepts or language.
• The request for renegotiation by a signatory or caucus must be submitted to the Water Forum Executive Director, who will bring it (or any request they may have) first to the Coordinating Committee for discussion. Coordinating Committee discussions will be

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 123
informed by input from their respective caucuses and, as appropriate, any guidance from relevant committees.
• The Coordinating Committee is to forward all requests on to the Plenary for its consideration. The Coordinating Committee may, at its discretion, offer an accompanying recommendation to adopt, modify, or reject. It may also forward it on to the Plenary without any recommendation.

A request for an amendment or renegotiation does not necessarily mean WF2050 will be revised.

WF2050, including specific agreements (e.g., PSAs), can be changed or modified only with the express approval and consent of the Plenary. Changes to WF2050 are the purview of the Plenary, with the caveat that changes that require additional funding will be subject to agreement by the funders. The Plenary may recommend that the proposed changes be referred to the signatory members’ boards/decision-making bodies for formal confirmation.

Specific implementing agreements (e.g., PSAs) cannot be changed or modified without the express approval and consent of the entity whose interests would be affected by the change.

These changes also must be approved by the Plenary.

3. Process for Project Endorsement from the Water Forum This program element is designed to provide a framework for projects proposed by Water Forum members to receive endorsement from the Water Forum, consistent with the decision-making processes described above.

Water Forum signatories may receive support (i.e., endorsement) for a proposed project from fellow signatories when agreed-upon conditions are met, including good faith sharing of project information and the project proponent’s commitment to WF2050 implementation. A “project” could refer to infrastructure, water entitlement, an application for funding, a policy, or a procedure. Endorsement can range from conceptual to full endorsement (as described below) and is dependent on the level of project development and information shared with the Water Forum.

Conceptual Endorsement
Definition: The project idea is acknowledged by signatories as relevant and aligned with the coequal objectives.

Purpose: Signals openness to explore the concept further.

Full Endorsement (Ready to Implement)
Definition: Water Forum signatories have confirmed support for the project’s final implementation.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 124
Purpose: Signals that the project is supported by all caucuses and implementation will not be opposed by Water Forum signatories.

When a project receives Water Forum endorsement, signatories (when called upon) will make reasonable efforts to provide endorsement in any (or all) of the following ways:
- Speak before stakeholder boards and regulatory bodies - Provide letters of endorsement
- Provide supportive comments to the media
- Advocate the WF2050 Agreement to other organizations, including environmental organizations that are not signatories to the Water Forum Agreement. - Otherwise, respond to requests from other signatories to make public their endorsement of WF2050 and associated projects (as relevant).

At a minimum, Water Forum endorsement of a project will mean refraining from making negative statements or opposing the project. However, conceptual endorsement does not preclude Water Forum signatories from asking questions and seeking clarity within various environmental review processes as projects are advanced.

If requested, an endorsement could come from individual signatories, the Plenary, or the Executive Director on behalf of the Plenary.

Framework for Information Exchange to Build Trust
Projects that receive Water Forum endorsement are those that have been shared and discussed widely with other Water Forum signatories. This could occur in caucus meetings, Plenary, Water Forum committees, or other Water Forum meetings that have been made available to all signatories. Discussions with signatories may be completed sequentially if access to information is made to all signatories in a timely manner. For instance, a project proponent could share their project details with all caucuses separately.

Inherent in this approach is the intent to build trust among signatories through full and early disclosure of project details. Sharing project information early in its development process will allow Water Forum signatories to evaluate, provide feedback, and engage in dialogue about the project. Project proponents should share project details in good faith before final decisions are made. The history of the Water Forum has shown that this type of information tends to garner support from other signatories.

In addition to the information sharing and disclosure process, projects may also receive Water Forum endorsement through the ARCAP , which will include analysis and assessment of regional actions to support the coequal objectives including through the potential development of

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 125
additional volumes of water. Projects considered within ARCAP are expected to undergo review and discussion through all levels of the Water Forum governance structure.

Project Endorsement Caveats and Assurances
1) The nature of a project endorsement will be commensurate with the level of detail shared with the WF and the level of development of the specific project. For example, if conceptual project information is available and shared with the WF, then WF signatories can only provide endorsement of the project’s concept. If project proponents seek full endorsement of a ready-to-build project, then it is expected that they will have shared and discussed details, including concept, design, funding, permitting, and construction, as relevant. 2) WF endorsement will be contingent on:
a. Proponent is adhering to all applicable planning, environmental, and regulatory requirements.
b. The proponent has conducted a public participation process, such as engaging with established citizen advisory committees or employing other appropriate mechanisms, to inform project design and implementation as needed. c. Project aligns with the coequal objectives and the WF 2050 guiding principles. d. The project proponent has demonstrated a clear commitment to WF2050 implementation.
3) If a consensus cannot be reached within the Water Forum for endorsing a project, no action will be taken by the Water Forum.
4) If a project is determined by consensus within the Water Forum to be in direct and clear conflict with the Water Forum’s coequal objectives, it is possible that the Water Forum would take a position of opposition to the project.
5) All signatories retain their existing ability to comment or provide input on specific details of facility design, financing, and construction of projects.

4. Legal Considerations
Administrative Structure
The Water Forum is not a legal entity, but rather a forum for a group of business and agricultural leaders, community groups, environmentalists, public and private water agencies, and local governments. Staffing and administrative support for the Water Forum are funded by water purveyors and other willing donors, with personnel management provided by the City of Sacramento. The Water Forum is not a separate legal entity. The current authority for the Water Forum is outlined in the 2025 Interagency Agreement for the Administration and Management of the Water Forum.

The key points of the 2025 Interagency Agreement for the Administration and Management of the Water Forum
(attached as Appendix 13) are as follows:

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 126
• The objective of the Water Forum office and staff is to promote the implementation and continued vitality of the Water Forum Agreement.
• The Executive Director of the Water Forum reports directly to the Director of the City of Sacramento Department of Utilities.
• The City is responsible for providing facilities, budget, and administrative support to the Water Forum.
• All employees of the Water Forum, including the Executive Director, are City employees. • The Water Forum contracting follows City procedures.
• The Water Forum will carry its own insurance policy to cover claims up to an agreed-upon threshold.
• If a signatory decides to terminate membership in the Water Forum, that signatory is responsible for covering their funding share for the current and subsequent fiscal year. • The City’s signature delegation policy identifies the Executive Director’s position as equivalent to a Department Director and authorizes contract authority of up to $100,000.

The City Attorney’s office represents the Water Forum on matters related to City procedures and general governmental issues. The Water Forum currently shares the City’s outside water counsel for advice on substantive water-related issues but has agreed to terminate the representation if a potential conflict with the City’s interests arises.

Water Forum Meetings – Relationship to Brown Act
The Water Forum is neither a local governing body nor was it created by federal or state law.

Accordingly, it is not subject to the Brown Act.

Nevertheless, the Water Forum strives to be as transparent and inclusive as possible, both with its members and with cooperating entities, affected parties, and the broader public. To that end, Plenary meetings are open unless a specific topic warrants member-only discussions. The Water Forum also strives to hold informational sessions that deepen understanding among its members and others. In the case of open Plenary meetings, the Water Forum will provide advance notice of meeting times and materials to inform the public. The general intent for Plenary meetings is to be open to the public so that the formulated plans and positions are made known.

The Water Forum strives to provide meeting materials to its members in a manner consistent with good public participation practices (e.g., meetings are noticed in advance, discussion topics are described in the agenda, meetings take place locally and are open to the public, etc.).

Water Forum members are responsible for ensuring their engagements with the Water Forum are consistent with their agency’s Brown Act obligations.

Caveats and Assurances

AMERICAN RIVER CLIMATE ADAPTATION PROGRAM (ARCAP)
ARCAP Caveats and Assurances include the following:

1. The ARCAP will be developed and implemented, with opportunities for open cross-caucus discussions and guidance, utilizing the Water Forum’s decision-making processes. This applies to both technical processes and member deliberations.

2. The Water Forum will work jointly with RWA and the GSAs to resolve technical issues during ARCAP development and implementation. Staff from RWA and the Water Forum will work together in a collaborative relationship to support this program and will engage with the regional GSAs.

3. The ARCAP approach will strive to add value and avoid creating added costs, duplicative processes, and bureaucracy.

4. The ability of Water Forum members to identify and employ ARCAP Water does not imply that the American River is in excess conditions.

5. ARCAP implementation will complement and support other Water Forum programs (e.g., FMS).

6. The Water Forum will review the successes and challenges of the ARCAP and refine the program as needed, with adjustments agreed upon by all caucuses.

7. ARCAP assets (e.g., water rights and contracts, wells, diversion works) will remain under the control of the owning agencies.

8. The role of the Water Forum (including its staff and members) will be to coordinate ARCAP actions, complete agreed-upon technical analyses and studies, advocate for programs and funding, and track and review the status of these programs.

9. The Water Forum and RWA will respect the operational authority and third-party agreements of their members, which are necessary for their contributions to ARCAP Water.

10. No part of the ARCAP will abridge the authorities, entitlements, or agreements of Water Forum members without the express consent of the relevant parties.

AMERICAN RIVER FLOWS AND OPERATIONS (ARFO)
ARFO Caveats and Assurances are grouped in the following categories:
• Flow Management Standard (FMS)
• Flood Operations
• Temperature and Other Water Management Infrastructure Flow Management Standard

1. Signatories acknowledge that, while minimum reservoir releases are a key feature of the FMS, flows above the specified minimum releases can provide important benefits for wildlife, recreational, and aesthetic values of the LAR.

2. Signatories acknowledge that low Dissolved Oxygen (DO) levels have a significant impact on the health of salmonids, thereby negatively affecting the benefits of the FMS.

Consequently, Folsom Reservoir complex management actions must take this factor into account to avoid unhealthy DO levels.

3. Signatories acknowledge that Folsom Reservoir storage levels in the spring are critical to the volume of cold-water pool available for the effective implementation of the FMS during the rest of the year, and that management actions should be taken to preserve as much reservoir storage as feasible during this timeframe.

4. All signatories agree to recommend to the SWRCB an updated American River Flow Management Standard that protects the fishery, wildlife, recreational, and aesthetic values of the lower American River. The recommendation will include requirements for Reclamation releases to the LAR.

5. The Water Forum will develop recommendations to inform transfer activity in the region, subject to agencies’ determinations of operational, regulatory, and contractual feasibility, to be as consistent with the FMS as possible and maximize the value of the transfer water for the health of the LAR.
a. Note: Current regulations include a commitment to implement certain aspects of the FMS, and water moved through a transfer agreement has the potential to offer additional flows and/or temperature benefits to the LAR, pending operational constraints such as, but not limited to, timing of deliveries, infrastructure capacity, regulatory or discretionary actions by Reclamation.
b. Note: When transfers are arranged with Reclamation, purveyors can make requests or suggestions regarding how and when water is moved through the system; however, operational decisions are ultimately at the discretion of Reclamation and are subject to regulatory requirements.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 130
Flood Operations

6. The Water Forum Signatories support pursuing a Preliminary Viability Assessment of American River Watershed Forecast-Informed Reservoir Operations34 (Watershed FIRO) in partnership with Reclamation, USACE, NOAA, and others, where appropriate and possible.

7. The Water Forum signatories support the identification and implementation of excess flood water recharge when: 1) carried out within the region; 2) designed, constructed, and operated in accordance with appropriate environmental and engineering standards/requirements, and the FMS; and 3) consistent with and supporting the Water Forum’s coequal objectives.

Temperature and Other Water Management Infrastructure

8. Signatories support the current efforts to redesign and improve the temperature control shutters at Folsom Dam and will consider opportunities for Water Forum support and advocacy. Until improvements are made, signatories support the implementation of a power bypass at Folsom Dam in all years as necessary to provide suitable fall spawning temperatures for LAR resident salmonids, unless September temperature modeling indicates that 56°F or lower can be achieved at Watt Avenue on or before November 1st without the bypass.

REGIONAL WATER SUPPLY SUSTAINABILITY (WSS)
WSS Caveats and Assurances are grouped in the following categories:
• Surface Water Management
• Groundwater Management
• Demand Management
• Dry-Time Actions
Surface Water Management

1. The ability for any individual purveyor to implement the surface water diversions principles will depend on their respective opportunities and constraints.

2. On a five-year cycle, purveyor signatories will coordinate with the Water Forum staff to provide data and assumptions to be reported in their Urban Water Management Plans (UWMPs), including demand projections, current and planned supplies, status of demand management and water use efficiency programs, and drought planning scenarios. Water

34 Definitions of FIRO can vary, but generally includes expanding meteorological, watershed, channel condition, and environmental monitoring; advancing technology to enhance meteorological, watershed, channel condition, and environmental forecasting; and integrating data collection, management, display, and analysis capabilities into decision support systems related to reservoir operations.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 131
Forum staff will compile regional data and assumptions for presentation to the Water Forum membership for review and discussion.

3. Nothing in the agreement is intended to call for the reduction or forfeiture of existing surface water entitlements. Signatories to the agreement will honor this principle in state and federal entitlement proceedings directly related to WF2050. It is recognized that there may be broader state and federal entitlement proceedings where signatories may have different interests, such as the SWRCB water rights proceeding for the Bay-Delta. Signatories agree to work in good faith through the Water Forum with the objective of developing a consensus recommendation for how state and federal entitlement proceedings should affect those agencies that store and divert American River water. All signatories will make good faith efforts to ensure that recommendations are consistent with both coequal objectives. a. The LAR is considered to be fully appropriated by way of the existing declarations of full appropriations, the responsibilities of the California Wild & Scenic Rivers Act, and the realities of the National Wild & Scenic Rivers Act. For more detailed information, see Appendix 6. The Water Forum will not be pursuing amendments to the existing declaration of full appropriation.

4. Recognizing that the majority of LAR surface water supply originates in the Upper American River Watershed, signatories support efforts above Folsom Reservoir to enhance and restore watershed health, creating a resilient headwater for water supply and ecosystem benefits on the American River.

5. The Water Forum did not evaluate new reservoirs in the analyses used to inform the WF2050 negotiations. Notwithstanding any provision of this agreement, any proposal for the Water Forum to support or oppose a new reservoir shall be approved by the Plenary, with at least 30-day notice to each Water Forum representative.

6. Signatories acknowledge that the parties to the Healthy Rivers and Landscape (HR&L) Proposal will be obligated to meet tributary program requirements for the American River, if approved by State Water Resources Control Board along with associated agreements. In addition, there are Water Forum members who have also made flow commitments pursuant the American River Terms for Ecosystem Support and Infrastructure Assistance Needs (ARTESIAN) Agreement

35. 7. Signatories are encouraged when invited to support (where possible) purveyors’ rates and fees necessary to implement projects and programs insofar as they are consistent with the WF2050 guiding principles and in support of the coequal objectives. The Water Forum will provide learning and engagement opportunities on water affordability and related best

35 The ARTESIAN Agreement contains commitments for certain RWA members to obtain funding to complete groundwater infrastructure projects and provide contributions to environmental outflow with or without adoption of the HR&L. The ARTESIAN Agreement governs the rights and obligations with respect to the administration of state funding provided for in the Funding Agreement Between the State of California (Department of Water Resources) and the Regional Water Authority - Voluntary Agreement Early Implementation for the American River, executed on July 21, 2023.

practices, and signatories will work to better understand associated challenges and opportunities (see Governance Program Element– Community Outreach and Engagement for more information).

Groundwater Management

8. The Water Forum will work to understand better and communicate the opportunities for, and impacts of, increased surface water diversions in wet conditions.

9. Signatories acknowledge the importance of continued data collection and analysis to improve understanding of Groundwater Dependent Ecosystems (GDEs) and surface water– groundwater interactions and commit to ongoing dialogue within the Water Forum as these topics are explored in the context of SGMA requirements and ARCAP analyses (as relevant).

Demand Management

10. All signatories acknowledge that the requirements related to water purveyors’ water use efficiency and demand management have become increasingly stringent since the signing of the original WFA and are continuing to evolve.

11. All signatories acknowledge that the purveyors must consider the costs and benefits of demand management actions (monetary, ecosystem, quality of life, etc.).

12. All signatories acknowledge that water rates have impacts on affordability and equity.

13. All signatories recognize that conserving water provides multiple benefits (if properly targeted, implemented, and managed) and commit to implementing demand management actions in a manner that strives to support both coequal objectives, with considerations for improvements to landscape irrigation efficiency and installation of native and low-water-use vegetation.

Dry-Time Actions

14. Water is essential for public health and sanitation, as well as for economic stability and quality of life. Water agencies have a fundamental responsibility to provide all customers with reliable access to safe, clean drinking water. This fundamental responsibility may constrain the breadth of Water Forum related actions purveyors are able to take during extreme drought.

15. Water agencies in California manage water shortages in accordance with their individual Water Shortage Contingency Plans (WSCPs), which are developed and updated every five years as part of their UWMPs, in compliance with California Water Code requirements.

16. Signatories acknowledge that dry times present exceptional challenges for the health of the LAR, and actions should be pursued to protect the fish that rely on river flows and temperature.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 133

SCIENCE, MONITORING, AND DECISION SUPPORT
Science, Monitoring, and Decision Support Caveats and Assurances include the following:

1. The level of effort and the scope of Science, Monitoring and Decision Support Program activities will be informed by emerging data needs, and science activities mandated by regional and/or statewide programs that may arise during the WF2050 term (i.e., the Statewide HR&LP Science Plan habitat accounting process, changing hydrology, new water supply regulations, etc.), and other emerging funding sources and requirements, as applicable.

GOVERNANCE, FUNDING, AND ADMINISTRATION
Governance, Funding, and Administration Caveats and Assurances include the following:

1. The nature of a project endorsement will be commensurate with the level of detail shared with the WF and the level of development of the specific project. For example, if conceptual project information is available and shared with the WF, then WF signatories can only provide endorsement of the project’s concept. If project proponents seek full endorsement of a ready-to- build project, then it is expected that they will have shared and discussed details, including concept, design, funding, permitting, and construction, as relevant.

2. WF endorsement will be contingent on:
a. Proponent is adhering to all applicable planning, environmental, and regulatory requirements.
b. The proponent has conducted a public participation process, such as engaging with established citizen advisory committees or employing other appropriate mechanisms, to inform project design and implementation as needed.
c. Project aligns with the coequal objectives and the WF 2050 guiding principles. d. The project proponent has demonstrated a clear commitment to WF2050 implementation.

3. If a consensus cannot be reached within the Water Forum for endorsing a project, no action will be taken by the Water Forum.

4. If a project is determined by consensus within the Water Forum to be in direct and clear conflict with the Water Forum’s coequal objectives, it is possible that the Water Forum would take a position of opposition to the project.

5. All signatories retain their existing ability to comment or provide input on specific details of facility design, financing, and construction of projects.

California American Water
Purveyor Specific Agreement
Updated: January 8, 2026
California American Water is submitting this document as a commitment to the Water Forum for surface water management of the American River. This agreement follows the Purveyor Specific Agreement (PSA) Template and Guidelines and addresses surface water management, current and future diversions from the American River, dry conditions management, critically low storage conditions in the Folsom Reservoir, and a project list to support coequal objectives. We recognize that climate variability is impacting water resources in the region. The continuing implementation of the historic Sustainable Groundwater Management Act (SGMA) in the Sacramento region provides opportunities to ensure alignment for the sustainable management of our shared water resources.

Purveyor Background
California American Water is an investor-owned utility operating under the rules and regulations of the California Public Utilities Commission (CPUC). California American Water has seven service areas within the metropolitan area of Sacramento County; (1) Antelope, which serves the communities of Antelope and Elverta; (2) Lincoln Oaks, which serves portions of Citrus Heights and North Highlands; (3) Parkway located in the Florin area, (4) Fruitridge Vista located in the Lemon Hill area, (5) Suburban/Rosemont, which serves Rosemont and the western portion of Rancho Cordova; (6) Arden in the Arden Arcade area, and (7) Security Park in the Sunrise Douglas area. Additionally, California American Water provides water to the West Placer service area, located just north of the Antelope service area in Placer County. As of January 2024, California American Water had 65,467 active connections within these eight service areas.

California American Water serves water to two additional areas within Sacramento County, the City of Isleton and the community of Walnut Grove; both areas rely solely on groundwater. California American Water’s service areas may be extended from time to time as approved by the CPUC.

Groundwater
Groundwater is the primary source of supply for California American Water’s systems in Sacramento County. All the Sacramento County water systems are within the boundaries of the Sacramento Valley Groundwater Basin of the Sacramento River Hydrologic Region as identified by California Department of Water Resources (DWR) in its Bulletin 118 updated in 2018. • Antelope, Arden, and Lincoln Oaks are located within the North American Subbasin.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 136
• Fruitridge, Parkway, Security Park, and Suburban-Rosemont are located within the South American Subbasin.

There are currently 101 active groundwater wells in these seven service areas. The total production capacity is approximately 70,720 gallons per minute (gpm). Table 1 summarizes the wells by service area.

California American Water does not use groundwater to supply its West Placer service area. Under a franchise agreement with Placer County, the provision of domestic water service by California American Water shall be consistent with the water source requirements and conditions adopted by the county as applicable to the specific county general plan policy, community plan, or zoning for, or directly affecting, the property to be so served.

Total 101 70,720

Purchased Water
California American Water’s Arden, Parkway, and Suburban-Rosemont service areas lie within the Place of Use (POU) for the City of Sacramento’s American River Water Rights. In 2010, California American Water revised an existing wholesale supply agreement with the City to receive a maximum of 3.46 million gallons per day (MGD) of non-firm supply (defined as surplus capacity in the City of Sacramento’s treatment and transmission facilities that is available to divert, treat and deliver potable water to California American Water after all the demands of the City’s prior wholesale and wheeling service customers and present and future retail water service customers are met) during off-peak periods (October 15th through May 14th), plus an additional 2.3 MGD of firm capacity, for a total of 5.76 MGD, that can be delivered to the Arden, Parkway, or Suburban-Rosemont service areas. The agreement stipulates that the City would supply surface water unless the Lower American River is below the Hodge Flow Criteria, in which case the City would produce groundwater instead of surface water when demands exceed 1.13 MGD. This mixed supply is available to California American Water up to 2.3 MGD.

California American Water also has an agreement with the City of Sacramento for the Fruitridge service area, which was carried over from the agreement between the Fruitridge Vista Water Company and the City. Through this agreement, California American Water can purchase up to 3.24 MGD of water from the City to serve its Fruitridge service area.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 137
Sacramento County Water Agency (SCWA) supplies water to the Security Park service area. The current agreement between California American Water and SCWA allows California American Water to take up to 50 gpm of potable water.

Sacramento Suburban Water District (SSWD) and California American Water have an agreement from 2005 that allows California American Water to purchase up to 2,000 AFY of water from SSWD to serve its Antelope and Lincoln Oaks service areas.

California American Water has an agreement with Placer County Water Agency (PCWA) to purchase water for its West Placer service area. The agreement allows for purchase of 3 MGD and a maximum delivery rate of 2,362 gpm. Additional capacity can be purchased if needed.

Surface Water Management
The coequal objectives of the Water Forum are (1) to provide a reliable and safe water supply for the region’s economic health and planned development and (2) to preserve the fishery, wildlife, recreational, and aesthetic values of the lower American River. With the exception of the West Placer service area, California American Water relies primarily on groundwater to serve its customers. However, as a member of three groundwater sustainability agencies (West Placer Groundwater Sustainability Agency, Sacramento Groundwater Authority, and Sacramento Central Groundwater Authority), California American Water must use groundwater responsibly and therefore prioritizes the use of purchased water within the limits of the purchase water agreements when it’s available, plentiful, and economically feasible.

Current Diversions
California American Water’s current diversions from the American River are through the four agencies from which California American Water purchases water . The supply sources from these agencies are described briefly below:
• City of Sacramento’s wholesale supply sources include American River and groundwater, the majority of this being from the American River.
• PCWA supplies water from Pacific Gas and Electric and the Middle Fork American River project and plans to deliver water from the Central Valley Project, supplied by the American River. • SCWA’s supply sources include surface water, groundwater, and non-potable (recycled) water.

Surface water is mainly supplied from the Sacramento River, with some diversions from the American River.
• SSWD relies primarily on groundwater, but imports water from Folsom Reservoir and the Lower American River through water purchases from PCWA and the City of Sacramento.

Table 4 summarizes the amount of water California American Water purchased from these four agencies for the past five years.

Table 4. Purchased Water (MG)
Wholesale Water Agency 2023 2022 2021 2020 2019
City of Sacramento 680.5 339.7 863.0 1481.7 460.9

SCWA 0.3 0.4 0.3 0.4 0.1
SSWD 290.4 0.0 2.0 48.8 482.9
Future Projected Diversions
Projected diversions consider conditions when the Unimpaired Inflow to Folsom Reservoir (UIFR) is above 950 thousand acre-feet (TAF). Under normal conditions, California American Water intends to use surface water as it is available through purchase water agreements with the City of Sacramento, PCWA, SCWA, and SSWD.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 139
Drier Conditions Management
“Drier conditions” is defined as the condition where the UIFR is between 950 TAF and 400 TAF. Supply management includes the following expectations:
• No change is anticipated in the availability of the City of Sacramento’s supply, as indicated in their 2020 UWMP . Regardless, California American Water commits to reducing the amount of purchased water from the City in drier years.
• SSWD has agreed not to use any water from the Lower American River in years other than wet years (when UIFR is greater than or equal to 1,600 TAF), although SSWD still would have groundwater available. Regardless, California American Water’s agreement with SSWD does not guarantee that supply will be available and it is assumed that in drier years, California American Water will plan for this supply source to be unavailable. • While the demand in Security Park can currently be met using groundwater, the service area is expected to grow significantly in the near future due to the Rio Del Oro development. California American Water intends to serve this area primarily with purchased water from SCWA, with groundwater as a back-up source for use during dry conditions. • PCWA does not expect to see a reduction in Middle Fork Project (MFP) supply in a dry year, although Pacific Gas and Electric Company (PG&E) and Central Valley Project (CVP) supplies would be reduced to 50%. Shortfalls in supply would be addressed by PCWA thorough groundwater production.

Driest Conditions Management
“Driest conditions” refers to the condition in which the UIFR is less than 400 TAF. In these conditions, supply will be managed under the following expectations:
• California American Water’s wholesale supply agreement with the City of Sacramento is subject to Hodge Flow Criteria on the Lower American River and inflow to the Folsom Reservoir (i.e., UIFR less than 400 TAF). The firm capacity component specifies a minimum of 2.3 MGD available throughout the year and the non-firm capacity of 3.46 MGD is available during non-peak periods. Although the City’s 2020 UWMP indicates that the City has adequate water supply to meet demands during multiple dry years through the year 2040, it is assumed that only the firm capacity will be available.
• As with the “drier” condition scenario, SSWD water is assumed to be unavailable for purchase during driest conditions.
• Similar to the “drier” year conditions, any reductions in supply from SCWA to serve Security Park will be met using groundwater, to the extent it is available. • PCWA does not expect to see a reduction in MFP supply during the driest conditions, but PG&E water will be assumed unavailable and CVP supplies would be reduced to 25%. Shortfalls in supply would be addressed by PCWA thorough groundwater production.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 140
Critically Low Storage Conditions
In the event of catastrophically low storage at Folsom Reservoir, two conditions must be addressed:

1. Potential operations in spring and summer when Folsom Reservoir storage is forecasted to reach 110 TAF at some point in the next 12 months.

2. Potential operations in summer and fall when Folsom Reservoir storage is below 110 TAF.

In both cases, California American Water will prioritize the use of groundwater wells and greatly reduce or eliminate the use of purchased water to the extent reasonably possible. In the case that purchased water includes groundwater, California American Water will prioritize use of its own groundwater wells to the extent reasonably possible, to allow other users access to wholesale agency groundwater water supplies.

While there are currently restrictions on California American Water’s use of groundwater to supply its service area in West Placer, California American Water’s agreement with PCWA does allow for California American Water to construct and use groundwater facilities, with the requirement that the use of PCWA water be prioritized, when available. The agreement further states that PCWA may instruct California American Water to reduce demand for surface water by up to 25 percent during periods of drought in areas where groundwater is available to ensure supply is available to other areas that do not have access to groundwater. Therefore, it may be feasible to negotiate with Placer County to obtain the ability to develop emergency groundwater sources.

Demand Management
California American Water has been offering conservation and water efficiency programs to its customers since the early 2000s. Conservation and efficiency programs help secure long-term water supply reliability, help with effective water demand management and peak water demand reduction, provide customer education on conservation and efficiency practices, and provide affordability by lowering customers’ water bills.

California American Water’s conservation and efficiency programs are also playing a critical role in the Company’s response to California state regulations and policies pertaining to water efficiency, water loss management, and groundwater management including California's Senate Bill 555 and the Sustainable Groundwater Management Act. Senate Bill No. 606 (2017-2018 Reg. Sess.) (“SB 606”) and Assembly Bill No. 1668 (2017-2018 Reg. Sess.) (“AB 1668”) created a new framework for long-term improvements in water conservation and drought planning commonly referred to as “Making Conservation a California Way of Life” regulation. The two bills strengthen the state’s water resiliency in the face of future droughts with provisions that include establishing water use objectives (“WUO”) and long-term standards for efficient water use that apply to urban retail water suppliers.

Two additional pieces of legislation, Senate Bill No. 555 (2015-2016 Reg Sess.) (“SB 555”) and Senate Bill No. 1157 (2022) together establish the comprehensive legislative framework for the WUO that water purveyors must comply with starting in 2027. The WUO is the sum of a water system’s use of indoor and outdoor residential water uses, commercial landscape irrigation, and distribution system water loss. The regulations also require water agencies to implement extensive non-residential water use performance measures and add substantial reporting requirements for water utilities to the state.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 141
The challenge for utilities will be to make customers adapt to these new WUOs through an increase in conservation and efficiency measures primarily on outdoor water usage.

Meeting the WUOs will require landscape transformation shifting from turf grass to more climate- adapted plant palettes according to the Model Water Efficient Landscape Ordinance (MWELO) Principles, a shift that will be very costly for homeowners and for utilities to incentivize this change.

Many water utility customers still seem mostly unaware of the Making Conservation a California Way of Life regulation and its implications for both residential and non-residential customers.

California American Water has invested greatly in educating its customers on conservation and efficiency matters and will continue to do so and its parent corporation, American Water, received the U.S.

Environmental Protection Agency’s WaterSense Excellence award in 2022 and 2023 for its various water efficiency customer education programs, foremost its webinar series launched for California American Water customers and for its collaboration with other organizations to continuously innovate its conservation programs.

California American Water is committed to its ongoing strong investments in conservation and efficiency programs and initiatives to meet and exceed water conservation regulations, to meet and exceed WUO and Water Loss targets and to assure reliable and safe future water supplies to our customers in the region.

As such, California American Water proposed conservation programs that will put the Company’s various service areas in the best position to comply with state regulations and policies pertaining to water conservation and water loss management as prescribed in the Making Conservation a California Way of Life framework. Additionally, California American Water has sought approval to maintain the Company’s ability to implement successful conservation programs through flexibility and innovation allowing cost- effective and efficient program execution and participation in partnerships, such as the Water Forum, with other agencies’ conservation programs.

As directed by Water Code Section 10632 (a)(3)(A), California American Water maintains a water shortage contingency plan (Rule 14.1) and associated enforcement tariffs (Schedule 14.1 SAC , FRT) that can be implemented upon approval by the CPUC based on operational service conditions and water supply availability.

Project List and Future Water Supply Reliability Efforts It is understood that to support the coequal objectives and mitigate challenges facing the region under future conditions, structural and non-structural projects will be needed. The following projects are anticipated to aid in California American Water’s efforts to implement the proposed commitments outlined in the PSA.

Structural

1. Well Rehabilitation and Replacement Program – California American Water implemented this program to ensure adequate water supply and to maintain or increase the performance of groundwater wells. Because California American Water’s service areas rely heavily on groundwater, this program helps to ensure that customer demands can be met through groundwater, and the purchase of surface water is minimized.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 California American Water PSA 142

2. Pipeline Replacement Program – This program was implemented to replace aging water mains, thereby reducing the risk of pipe leaks and breaks. Leaks and breaks contribute to water loss, increasing overall system demand. By decreasing water loss, California American Water decreases overall demand, including the need to purchase surface water.

3. Advanced Metering Infrastructure (AMI) – California American Water is upgrading meters to AMI. Information collected through this metering system can assist in identifying and reducing system losses.

Non-Structural

1. Water Conservation Program – California American Water encourages water conservation through efforts such as customer education and information, contributions to research on innovative conservation programs and products, and participation in committees that promote conservation measures. These actions help reduce overall demands and especially peak demands, which reduces reliance on surface water.

2. California American Water helped sponsor the River Arc project in the past, and although no longer a project partner, California American Water continues to support the project and believes it is an important project for the future of reliable water supply in the Sacramento area.

Caveats and Assurances

1. The ability for any individual purveyor to implement the surface water diversions principles will depend on their respective opportunities and constraints.

2. In circumstances where excess water is made available by the U.S. Bureau of Reclamation (Reclamation) by Article 3(f) of a purveyor’s Water Repayment Contract or by a Section 215 Contract between the purveyor and Reclamation due to flood control operations at Folsom Reservoir, for the purposes of groundwater recharge, that water would not be counted as diversion water within their PSA, regardless of year type.

3. California American Water is governed by the CPUC. California American Water’s agreed endorsements in, or continued implementation of, this PSA are subject to review by the CPUC.

California American Water may modify or terminate its endorsements agreed to in, or implementation of, this PSA upon receiving an adverse decision relating to said endorsements or implementation by the CPUC.

4. California American Water’s operations, facilities, and contracts as described in this PSA may be modified, revised or amended from time to time, and this PSA is not intended to restrict California American Water’s ability to execute and implement such modifications, revisions, and amendments. California American Water shall not be required to update or otherwise amend this PSA in the event of any such modifications, revisions, and amendments to its operations, facilities, and contracts.

5. As part of the development of their quinquennial UWMPs, purveyor signatories will provide information to Water Forum staff and signatories related to the data and assumptions to be reported in their UWMPs, including; demand projections, current and planned supplies, and

Carmichael Water District
Purveyor Specific Agreement
Updated: November 26, 2025
Purveyor Background
Carmichael Water District (CWD or District), formerly Carmichael Irrigation District, was formed in 1916 to serve water for irrigation and a small but growing township called “Carmichael Colonies”. The District was formed under the California Irrigation District laws but changed its name to Carmichael Water District in the 1980s to reflect its transformation from a primarily irrigation water supplier to an urban water supplier. Today, CWD serves about 11,900 connections with a population of about 40,000 people.

With a history of over 100 years, the District is built out with 90% residential service and a steady decrease in water demand from effective water efficiency campaigns and education.

The District’s water supply portfolio has provided over 100 years of water supply reliability to its customers. The District’s transition from exclusive use of surface water diverted from the American River to groundwater use and then to a sophisticated conjunctive use program, including a state-of-the-art water treatment facility, epitomizes the flexibility and adaptability that the District has displayed throughout its history. Renewed flexibility and adaptability will allow the District to handle climate change, regulatory change, and legislated conservation and water quality protection.

CWD has three main water supplies in its portfolio: surface water rights to divert the natural flows of the American River, groundwater supplies derived from its well system including banked water supplies from its long-term conjunctive use activities, and remediated groundwater supplies from its contract with Aerojet-Rocketdyne Corporation. All these water supplies are collectively managed to meet the District’s demands.

Surface Water Supplies
CWD’s surface water supplies consist of three appropriative water rights derived from the natural flow of the American River where water is normally available under natural conditions, subject to more senior appropriators. The supply is based upon water availability that is tied to the priority dates of these water rights. The State Water Resources Control Board (State Board) determines when there is insufficient water supply in the American River watershed to satisfy CWD’s diversion rate under each water right.

The three appropriate water rights consist of two licensed and one permitted water right providing up to 32,600 acre-feet per year (AFY) with a maximum diversion rate of 50 cubic feet per second, depending

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 Carmichael Water District PSA 145
on the season of use. CWD’s water rights have priority dates after 1914 and are subject to curtailment by the State Board.

Water Right Priority Date Diversion Rate Volume (AFY) Diversion Period License 1387 1915 15 cfs 10,859 Jan – Dec
License 8731 1925 10 cfs 3,669 May – Oct
Permit 7356 1948 25 cfs 18,099 Jan – Dec
The District diverts surface water through three Ranney collector wells in the American River and treats water at the Bajamont Water Treatment Plant (BWTP). The Ranney collectors use a series of laterals extending to the riverbed to gather water and utilize the natural sands and gravel for riverbank filtration.

Water flows from the collectors by gravity to a central collector and then the District conveys it to BWTP through a 48-inch pipeline.

Groundwater Supplies
Groundwater supplies constitute a major component of the District’s water supply portfolio. The District conjunctively manages its surface water and groundwater supplies to optimize the uses of these water assets.

The District currently operates 4 groundwater wells and is in the process of replacing 2 old wells and constructing a new well. These projects are in various stages of construction and are projected to be completed in 2026. The projected capacity for the wells will be about 8,000 to 10,000 gallons per minute (11.5 million gallons per day (MGD) to 14.4 MGD).

The District plans to further its conjunctive use program by utilizing Aquifer Storage and Recovery (ASR) technology to inject treated water from the BWTP when surface water is plentiful to maintain groundwater levels in the basin. The estimated annual capacity for storage is about 1,500 AFY to 3,000 AFY during normal and wet years. The District plans to invest additional resources in conjunctive use and water banking and will continue to implement additional ASR wells when replacing old wells that have reached the end of their useful life.

Alternative Supplies
The District may access remediated groundwater supplies from the Aerojet Groundwater Extraction and Treatment (GET) LA and LB facilities located within the District’s service area. Aerojet makes these water supplies available through the extraction, treatment, and discharge of groundwater into the American River. The District has exercised its option to divert this remediated groundwater when its surface water rights have been curtailed.

Distribution System of Note
The District’s water delivery system consists of both a distributed supply from groundwater wells and a centralized supply from the BWTP . The supply capacity is aided by two ground level water storage tanks, the La Vista Tank and the Dewey Tank, with a combined available storage capacity of 4 million gallons.

The network of distribution pipelines consists of water supply mains ranging in size from 4-inch to 18- inch pipes to larger water mains of 24-inch and 30-inch pipes.

The District also maintains an intertie with Fair Oaks Water District and Citrus Heights Water District and four interties with Sacramento Suburban Water District.

Surface Water and Groundwater Management
The table below summarizes District water demand (by source) from 2006 through 2024. The Purchased Water column indicates additional water acquired and used during surface water right curtailment periods via short-term temporary contracts with Aerojet for additional remediated groundwater, when available, and with San Juan Water District. These contracts were single-year contracts, and the supplies are no longer available. The District’s total demand has decreased significantly since 2006.

Future Projected Diversions
As the District is built out, the future projected diversions are expected to be similar to current conditions. Future in-fill projects will most likely reduce current irrigated areas and comply with regulatory water conservation standards. Future water efficiency measures will also limit additional diversions from the American River.

Future diversions from the American River may increase during normal and wet years by 1,500 to 3,000 AFY for storage of surface water in the groundwater basin via ASR operations.

Wet Conditions Management
Wet conditions occur when the Unimpaired Inflow Folsom Reservoir (UIFR) is greater than 1.6 Million Acre Feet. This threshold is not considered a formal definition of what constitutes a “wet year” or “wet conditions” on the American River but was utilized in the original Water Forum agreement as a basis for surface water commitments. It is expected that additional analysis and discussions will be conducted as part of the American River Climate Adaptation Program (ARCAP) to explore and define what other potential criteria could be used to guide regional operations in wet times. Where possible, the District will expand its conjunctive use operations and increase its diversions to groundwater storage by 1,500 to 3,000 AFY through its ASR wells.

Drier Conditions Management
In drier conditions, when the UIFR is between 950 Thousand Acre Feet (TAF) and 400 TAF, the District will implement water conservation measures to reduce demand by 10% from normal, or as required by the District’s Water Shortage Contingency Plan. Where possible, the District will prioritize groundwater use to leave water in the LAR.

Driest Conditions Management
In the driest conditions, when the UIFR is less than 400 TAF, the District will implement water conservation measures to reduce demand by 10 – 20% from normal or as required by the District’s Water Shortage Contingency Plan. Where possible, the District will prioritize groundwater use to leave water in the LAR.

Critically Low Storage Conditions
In critically low Folsom Reservoir storage conditions, the District would most likely be required to cease water diversions from the LAR per curtailment orders issued by the State Board or terms and conditions in the Healthy Rivers and Landscapes Agreements. If curtailed, the District would use its groundwater resources to meet demands and, if necessary, acquire additional water to supply demands as available.

The District would also implement its Water Shortage Contingency Plan that aligns with a potential water supply shortage and comply with any applicable mandates issued by the State Board.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 Carmichael Water District PSA 148
Demand Management
CWD is committed to abide by relevant water conservation and water use efficiency regulations. At the time of signing, key requirements are associated with the 2024 “Making Conservation a California Way of Life” regulations, Assembly Bill (AB) 1572 related to irrigation of non-functional turf with potable water, and the Model Water Efficient Landscape Ordinance (MWELO), which encourages low water use and native landscaping for new development.

CWD has participated and will continue to participate in the Regional Water Authority’s Water Efficiency Program, especially for regional compliance with the Commercial, Industrial, and Institutional (CII) best management practices and regional non-functional turf outreach, along with regional messaging. CWD also offers water efficiency surveys and rebates for turf replacement, smart sprinkler controllers, and Flume Water’s Smart Home Water Monitor and Leak Detector. Continuation of the rebate program is subject to CWD Board of Directors approval.

Potential demand management actions include:
• Developing programs to assist in the conversion of publicly owned, commercial, and institutional landscaping to low-water-use native landscaping.
• Expand and strengthen regional conservation messaging about plant watering needs. • Provide additional water use efficiency rebates to customers. • Track customer water use and develop targeted outreach opportunities for high-water-use customers.
• Maintain and implement water waste prevention programs. • Maintain customer outreach and communication programs to educate and inform customers of state water use efficiency requirements.
• Maintain customer programs to support the implementation of Best Management Practices for the CII sectors.

Project List
Structural
Rehabilitation, modernization, or replacement of existing infrastructure as outlined below:
• Rehabilitation and replacement of Ranney collector laterals to maintain capacity and infrastructure integrity.
• Replacement of existing wells at the end of their useful life and modernize with ASR capabilities. • Replacement of existing pipelines in poor condition to improve water transmission reliability. • Distribution pressure zone modifications for efficient water use and energy management. • New groundwater facilities consistent with the adopted Groundwater Sustainability Plan. • Projects and programs to ensure success of the Healthy Rivers and Landscapes Program or a similar tributary-specific program that improves the ecosystem, protects local water entitlements, and maintains better cold water pool conditions in Folsom Reservoir and the LAR.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 Carmichael Water District PSA 149
Non-Structural
• Water transfers when available consistent with the Groundwater Sustainability Plan and the Water Code.
• Additional groundwater storage opportunities in the Sacramento Regional Water Bank. • Support and participate in regional partnership opportunities with other water purveyors that provide reliability to regional water supply systems and benefits to the LAR. • Agreements with neighboring purveyors for conjunctive use opportunities. • Extension and/or license of water entitlements.
• Regional water efficiency and conservation campaigns.

Caveats and Assurances

1. CWD was established over 100 years ago and is mostly built out. Structural projects listed above for rehabilitation, modernization, or replacement of existing infrastructure are key for water supply reliability to its customers. CWD seeks support in implementation of rehabilitation, modernization, and replacement of old infrastructure for supply reliability, operational efficiency, and water conservation objectives.

2. The District uses surface water supplies, when possible, to protect its groundwater supplies and prevent migration of contaminant plumes associated with the Aerojet facilities in Sacramento County. The District will continue to practice conjunctive use to meet existing and future needs and manage dry and critically dry conditions as they arise in the future.

3. Acknowledge that the duty of a water purveyor is to simultaneously provide an affordable, reliable, and high-quality water supply to its customers. Proposals that favor one of these goals over another could threaten a water purveyor’s ability to achieve all goals simultaneously.

City of Folsom
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
The City of Folsom (City) is a public agency that provides potable water directly to its residential and business customers. The City’s boundaries are not coterminous with the City’s water service area. The City’s water system is divided into five (5) distinct water service areas. The water service areas are listed below and shown in Figure 1.
• Folsom West Service Area
• Folsom East Service Area
• Nimbus Service Area
• Folsom Plan Area Service Area
• Ashland Service Area
The City obtains its surface water supply directly from a diversion point in Folsom Reservoir. The City’s water service contracts allow it to develop an intake facility at the Folsom South Canal, but the City has not yet done so. For areas south of the American River, the City takes deliveries from the Natoma Pipeline, a 42-inch steel pressure pipe that originates at Folsom Dam. The Natoma Pipeline splits into two separate lines: one line to the Folsom Prison water treatment plant (WTP), and one line to the Folsom WTP . At the inlet to the Folsom WTP , the raw water line splits. A portion of the raw water is delivered to the Willow Hill Reservoir. This portion of the water has served non-potable industrial uses on the Aerojet Industrial Property (Aerojet). The balance of the water is delivered to the Folsom WTP .

After treatment at the Folsom WTP , water is stored and pumped through a system of reservoirs and pumping stations to seven pressure zones. Groundwater Extraction and Treatment (GET) A and B facilities are now being used to serve most of Aerojet’s non-potable water needs, which has allowed the City to reduce surface water diversions from Folsom Reservoir since 2015.

For the Ashland Service Area, water is diverted from the Folsom Reservoir and piped to the Sydney N.

Peterson WTP , which is owned and operated by San Juan Water District (SJWD). After treatment, water is stored in Hinkle Reservoir until SJWD releases and pumps it to the Ashland Service Area. While SJWD provides wholesale water supplies to the Ashland Service Area, it is conveyed to customers through City infrastructure, including service connections with meters. The water delivered to Ashland Service Area derives from SJWD’s water entitlements and contracts.

Water Forum Agreement 2050
February 2026 City of Folsom PSA 152
The City previously delivered raw water supplies to Aerojet at its industrial facilities; however, remediated water derived from GET A and GET B is now directly plumbed into Aerojet facilities for non- potable purposes. Even though the City does not deliver remediated water to Aerojet, the City does have rights to the remediated water, which they can utilize for non-potable use within the City’s water service areas. This remediated supply could offset raw or potable water demands on the City’s water system that are derived from its water entitlements and contracts and delivered from Folsom Reservoir.

The City’s 2023 demands from its own surface water entitlements and contracts are approximately 17,700 acre-feet. At the peak of the City’s surface water diversions from its own entitlements and contracts in 2008, total surface water diverted was 29,560 acre-feet serving a population of approximately 53,375. The 2023 population served using the City’s entitlements and contracts was approximately 71,550. The overall water use reduction from 2008 to 2023 is approximately 40% while the population increased by approximately 34% during that same period.

The City’s projected build-out demands derived from the City’s water entitlements and contracts are approximately 25,500 acre-feet per year in 2045 to serve a population of approximately 108,530. For the Ashland Water Service Area, from San Juan Water District’s water entitlements and contracts, 2023 demands were approximately 1,100 acre-feet and build-out demands are approximately 1,120 acre-feet per year. Table 1 summarizes the City’s water entitlements and contracts. The Ashland Water Service Area is mostly built-out with a 2023 population of approximately 3,400 with an expected population of 3,600 at build-out.

Surface Water and Groundwater Management36
Some of the City’s water supplies are subject to reduction under certain conditions. These conditions may manifest through (a) hydrological circumstances, like a drought; (b) the City’s regional relationships, like the Water Forum; and (c) legal and regulatory constraints, like species protection in the Sacramento- San Joaquin Bay Delta, curtailment orders from the State Water Resources Control Board, or an Executive Order from the Governor. Water supply reductions impact the availability of each water asset in a different way that may impact the City’s operations and long-term planning. These aspects of the City’s water supplies are outlined below. The City does not currently pump any groundwater and does not have any groundwater pumps or related infrastructure to pump groundwater.

Pre-1914 Rights for 22,000 AFY
The City’s 22,000 acre-feet per year (AFY) entitlement is based on a pre-1914 appropriative right from the South Fork of the American River established by the Natoma Water Company in 1851. The Natoma Water Company’s original pre-1914 water right established a maximum diversion rate “to fill a Canal Eight feet wide and Four feet deep with a current running ten miles per hour.” This correlates to a diversion rate of 60 cubic feet per second (cfs) and a maximum allocation of 32,000 AFY . This right is held jointly with Golden State Water Company (GSWC) pursuant to a co-tenancy agreement. The co-tenancy agreement means that both the City and GSWC have the right to use the water to the fullest extent possible as desired by the respective entities. The City and GSWC have allocated the supplies under the entire 32,000 AFY water right. The City unilaterally controls 22,000 AFY and GSWC controls the remaining 10,000 AFY .

The 1851 filing is the earliest in priority of perfected appropriative rights on the South Fork of the American River and is recorded. The entire 22,000 AFY of this water right is formally recognized in the settlement agreement between the U.S. Bureau of Reclamation (Reclamation) and the City. Under this agreement, Reclamation delivers this entire water supply without reduction on a permanent basis. This water asset may be diverted at its point of diversion in the water right itself, as well as Folsom Reservoir and Folsom South Canal pursuant to the settlement agreement between Reclamation and the City. The settlement agreement also requires Reclamation to deliver the entire supply under this water asset in all year types.

Pre-1914 Rights for 5,000 AFY
The City’s 5,000 AFY entitlement is also based on Natoma Water Company’s pre-1914 appropriative water right from the South Fork of the American River. In November 1994, the City executed a contract with Southern California Water Company-Folsom Division (SCWC) under which the City acquired the right to lease 5,000 AFY of water per year. As described above, SCWC controlled the remaining 10,000 AFY of the 32,000 AFY total water right under the original co-tenancy of the Natoma Water Company purchase. As such, the basis of this water asset is held with GSWC pursuant to the co-tenancy agreement, but the lease of the water asset to the City is pursuant to a lease agreement. This water right is also formally recognized in the settlement agreement between Reclamation and the City.

36 The City of Folsom does not currently pump any groundwater. Although the City does not currently pump any groundwater, the City is a member of the Sacramento Groundwater Authority and the Sacramento Central Groundwater Authority.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Folsom PSA 154
This water asset for 5,000 AFY has the same diversion provisions as the 22,000 AFY diversion right above since both assets are derived from the same water right. Moreover, this water asset has the same priority as the 22,000 AFY water asset which makes it extremely resilient against drought conditions and regulatory curtailment.

Central Valley Project Repayment Contract for 7,000 AFY On April 8, 1999, Reclamation entered Contract No. 6-07-20-W1372 with the Sacramento County Water Agency (SCWA) under Section 206 of Public Law 101-514, which was sponsored by Representative Vic Fazio. The contract dedicated 22,000 AFY of water, commonly called “Fazio Water,” to SCWA. The City was specifically named in the SCWA-Reclamation contract as a subcontractor to gain benefit of a portion of the Fazio Water supply. On April 25, 2000, SCWA entered a separate contract with the City to provide the City with 7,000 AFY of the 22,000 AFY of Fazio Water.

The Fazio Water supply is a standard Central Valley Project (CVP) “Project Supply” water entitlement – derived entirely from federal CVP water supplies. The sole source of supply for the Fazio Water is the American River water rights held by Reclamation for diversion and storage at Folsom Reservoir.

Reclamation’s CVP rights to divert water are junior to the water rights that existed prior to the development of the CVP . The Fazio Water contract entitlement for the City is fairly reliable. In normal and wet years, the City may call upon the supply for delivery and should receive 100% allocation. In dry years, the water supply is subject to Reclamation’s Municipal and Industrial (M&I) Water Shortage Policy.

In December 2016, the City became a direct CVP Contractor, and no longer a sub-Contractor to SCWA, through a partial assignment of the City’s 7,000 AFY under Contract No. 6-07-20-1372B with Reclamation. The purpose of this assignment is to consolidate the City’s water assets derived from the City’s relationship with Reclamation to better facilitate administration of those water assets. In February 2020, the City and Reclamation executed a contract (Contract No. 6-07-20-W1372B-P) to convert 37 the
CVP water service contract into a CVP repayment contract as authorized under the Water Infrastructure Improvements for the Nation Act.

Current Diversions
Table 2 summarizes the annual pre-1914 and CVP diversions made by the City from 2013 to 2023. These diversions all occurred from Folsom Reservoir and include both potable and non-potable uses. These totals do not include water delivered to the Ashland Service Area as that area is supplied from the SJWD water supply portfolio and not from water diverted by the City.

Future Projected Diversions
The future projected diversions under “normal” conditions (as shown below) are for when the Unimpaired Inflow to Folsom Reservoir (UIFR) is above 950 TAF. The City’s 2020 Urban Water Management Plan (UWMP) identified these diversions in five-year increments to 2045, which is also the planning date for build-out of the City. The current 5-year UWMP projections will serve as the basis of diversions when the UIFR is above 950 TAF. Diversions will derive from a combination of the City’s pre- 1914 and CVP water supplies. Table 3 shows the diversions under this condition.

Wet Conditions Management
Wet conditions will be assumed to be when the UIFR is greater than 1.6 MAF. This threshold is not considered a formal definition of what constitutes a “wet year” or “wet conditions” on the American River but was utilized in the original Water Forum agreement as a basis for surface water commitments.

It is expected that additional analysis and discussions will be conducted as part of the American River Climate Adaptation Program (ARCAP) to explore and define what other potential criteria could be used to guide regional operations in wet times. Where possible, the City will support the use of regional surface water supplies to assist in regional groundwater recharge.

Drier Conditions Management
When the UIFR is between 950 TAF and 400 TAF, the City will reduce surface water diversions up to 10 percent or as required by the City’s Water Shortage Contingency Plan 38, whichever is greatest. The City
will also reduce CVP diversions (included in the overall 10%) as required by the CVP M&I Water Shortage Policy.

Driest Conditions Management
When the UIFR is less than 400 TAF, the City will reduce surface water diversions up to 20 percent, as required by the City’s Water Shortage Contingency Plan, or as required by any mandates issued by the State of California, whichever is greatest. The City will also forego scheduling any CVP Repayment water during these conditions (included in the overall 20% or more). The City can offset surface water

38 The City’s Water Shortage Contingency Plan is based on water shortage events that directly impact the availability of the City’s water supplies. The Plan is not based on the UIFR.

reductions through conjunctive use opportunities with neighboring purveyors or through water stored in existing or future surface water storage.

As an example, if the City is able to bank water in the groundwater basin and another purveyor with access to surface water and groundwater can extract the banked groundwater and use this banked water to meet their demands while at the same time reducing their surface water diversions, the City will be able to deliver this surface water to meet its customer demands. Under these arrangements, other purveyors will use groundwater in lieu of surface water equivalent to the amount that the City would continue to divert.

However, it is recognized that in years when the projected UIFR to Folsom is less than 750,000 AF there may not be sufficient water to provide the purveyors with driest year quantities specified in their agreements and provide the expected flows to the mouth of the American River. In those years, Folsom will participate in a conference year with other stakeholders on how the available water should be managed. The conferences will be guided by the conference year principles described in the Water Forum Agreement.

Critically Low Storage Conditions
The City’s sources of water are all delivered through an M&I intake in Folsom Dam, which is at an elevation that would be subject to air entrainment at approximately 110,000 AF of storage in Folsom Reservoir. Because this entrainment could result in significant damage to the impellers of the pumps that Reclamation uses to pump the supplies brought through the intake to Folsom, Reclamation will install 10 floating pumps with a total capacity of 30 cfs. This arrangement will allow delivery of emergency supplies in extreme conditions even when the storage level is as low as 60,000 AF. The 30 cfs capacity of these emergency pumps is half the flow rate Reclamation is required to deliver to the City under its pre-1914 settlement agreements.

The City completed a Water Vision planning study that is a comprehensive 50-year strategy designed to secure and strengthen the City’s long-term water supply. This included an analysis of risks and vulnerabilities associated with infrastructure failure and a changing climate. The primary objective was to evaluate and recommend ways to improve the reliability and redundancy of the City’s water supplies, including but not limited to, a scenario of not having access to water supplies from Folsom Reservoir.

Ultimately, the Water Vision developed a phasing plan with recommended projects that would diversify the City’s water supply portfolio if access to current water supplies from Folsom Reservoir could not be achieved.

The City could also work with neighboring water purveyors to deliver treated groundwater through existing or new interties with the City. The City would also have to implement its Water Shortage Contingency Plan that aligns with a potential water supply shortage and would have to comply with any applicable mandates issued by the State of California.

City of Roseville
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
The City of Roseville Environmental Utilities Department (Roseville) is a public utility owned and operated by the City of Roseville, providing drinking water, wastewater, recycled water, and waste services to the Roseville community.

Roseville recognizes that climate change, population growth, and regulatory requirements are creating increasing challenges in balancing water supply and demand. Groundwater and surface water alike are under pressure, and Roseville is committed to advancing sustainable solutions that protect both resources for future generations, while maintaining our commitment to the health of the lower American River (LAR).

To address these challenges, Roseville participated in the American River Basin Study (ARBS) that was completed in 2022. The study was developed by the U.S. Bureau of Reclamation (Reclamation) in partnership with Roseville and other regional water agencies. Building on earlier statewide studies, the ARBS focused specifically on the American River Basin; developing tools, analyses, and climate adaptation strategies to strengthen water supply reliability, protect endangered species, and support sustainable reservoir operations. Roseville’s participation reflects our awareness of climate change challenges and our commitment to working collaboratively with local, state, and federal partners to bring forward long-term, regional water solutions for our community, the region, and the LAR.

In addition, Roseville has embraced the requirements of the Sustainable Groundwater Management Act (SGMA) and is an active member of the West Placer Groundwater Sustainability Agency (WPGSA), which manages a portion of the North American Subbasin alongside Placer County, the City of Lincoln, Placer County Water Agency (PCWA), and California American Water. Through this partnership, Roseville and our Groundwater Sustainability Agency Partners are implementing a Groundwater Sustainability Plan (GSP) that protects against groundwater overdraft, supports reliable supplies for residents, agriculture, and businesses, and contributes to land and habitat conservation.

Roseville also continues to expand our Aquifer Storage and Recovery (ASR) program as part of a conjunctive use strategy, which is further discussed in this Purveyor Specific Agreement (PSA). This innovative approach safeguards our groundwater basin, improves regional resilience, secures reliable

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 161
water supplies and can be used in a conjunctive way to benefit the LAR, particularly during the driest years.

Together, these efforts underscore Roseville’s commitment to climate change adaptation, groundwater sustainability, and regional collaboration, helping to ensure a resilient water future for our community, the region, and the LAR.

With these challenges, Roseville has developed diversity in its water supply and its water infrastructure over the past three decades to become more resilient and positioned to meet the Water Forum’s coequal objectives of water supply reliability and river corridor health.

The primary water supply for Roseville is surface water diversions from Folsom Reservoir. Roseville has contracts with Reclamation for up to 32 thousand acre-feet (TAF) of water per year, and PCWA for up to 34 TAF per year. Raw water from Folsom Reservoir is conveyed to Roseville’s water treatment plant in the Granite Bay area and is then distributed through Roseville’s 600 miles of water mains to customers.

Current surface water entitlements total around 66 TAF per year. Roseville maintains options for an additional 10 TAF of water supplies from PCWA, and although those options are contractually available, they have not yet been exercised.

Roseville also currently has 7 Aquifer Storage and Recovery (ASR) wells providing a maximum extraction capacity of 23.5 TAF/year. Roseville is planning to expand their groundwater program to have a more robust water supply available in the event of a water shortage. Roseville’s ASR program also has the capacity to inject approximately 11 TAF of treated water back into the groundwater basin.

Roseville has a Recycled Water Program with source water from two regional wastewater treatment plants that operate with an annual production rate of approximately 3.8 TAF of recycled water annually.

This water serves the landscape watering needs of parks, golf courses, and medians in the newer western section of Roseville.

Roseville has 17 interties with the surrounding purveyors including PCWA, San Juan Water District (SJWD), California-American Water Company, Citrus Heights Water District, and Sacramento Suburban Water District (SSWD).

Roseville has invested heavily in long-term water efficiency efforts over the last couple of decades, and, as per capita water use has declined, water demands have remained relatively stable despite population growth in the area.

Surface Water and Groundwater Management
The following sections outline the opportunities for Roseville to contribute to both of the Water Forum coequal objectives, while adhering to the guiding principles for surface water diversions.

1. Roseville intends to prioritize alternative water supplies to surface water supplies from the American River system in dry conditions to provide flow and water quality 40 benefits for the LAR,
such as:
• Pursuing opportunities for increased groundwater pumping to allow surface water to remain in the LAR.

40 Including temperature, dissolved oxygen, and potentially other characteristics.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 162
• Pursuing opportunities for increased diversions from the Sacramento River as an alternative to surface water from the American River system.

2. Ensure surface water commitments are in balance with regional efforts for groundwater sustainability.
• Prioritize surface water diversions in wet conditions to allow groundwater recharge.

3. Protect regional surface water entitlements to ensure local control of water to benefit the coequal objectives, with the following benefits:
• Enabling contributions to river corridor health.
• Reducing surface water diversions from Folsom Reservoir in the driest conditions. • Contributing to water supply reliability.
• Enabling the expansion of groundwater infrastructure to allow for conjunctive use.

Current and Projected Surface Water Diversions
Current Roseville demands are approximately 32 TAF per year, including ASR, and are expected to grow to just under 63 TAF per year in 2040.

Wet Conditions Management
Roseville’s intent for managing surface and groundwater under wet conditions is to follow the groundwater management guiding principles in the Water Forum Agreement 2050 (WF2050), as follows:
• Support conjunctive management of regional groundwater basins with surface water supplies to enhance water supply reliability and provide flow and water quality benefits to the LAR. • Prioritize use of groundwater in dry conditions to help mitigate the impacts to surface water shortages in the LAR by supplementing Central Valley Project (CVP) water allocations from the American River with groundwater using our existing and planned aquifer storage and recovery wells.
• Work with Reclamation to maximize groundwater recharge with Repayment Contract Article 3(f) water
41 during wet years42 with the goal of minimizing impacts to the LAR. • Participation with our regional partners in the Sacramento Regional Water Bank Project. • Continued investments in Aquifer Storage and Recovery (ASR) facilities. • Commitments related to reduced surface water diversions that are based on hydrologic conditions.

41 Article 3(f) water is what Reclamation provides currently, when available, based on Reclamation’s preference.

Section 215 water has been available to Roseville by Reclamation in the past. As such, the source of the water made available for recharge purposes has varied and may vary in the future. 42 Wet conditions will be assumed to be when the Unimpaired Inflow Folsom Reservoir (UIFR) is greater than 1.6 MAF.

This threshold is not considered a formal definition of what constitutes a “wet year” or “wet conditions” on the American River but was utilized in the original Water Forum agreement as a basis for surface water commitments. It is expected that additional analysis and discussions will be conducted as part of the American River Climate Adaptation Program (ARCAP) to explore and define what other potential criteria could be used to guide regional operations in wet times.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 163
Drier Conditions Management
The sections below describe the proposed commitments in Baseline (Normal), Dry, and Driest conditions. The proposal follows the existing Water Forum Agreement structure with Unimpaired Inflow to Folsom Reservoir (UIFR) as the index. The levels of surface water diversions are proposed to be updated based on 5-year projections for demand estimates as reported in Roseville’s Urban Water Management Plan (UWMP). These diversions would be updated based on each 5-year update to the Roseville UWMP .

Normal Conditions
Normal conditions would be defined as when the UIFR is projected to be greater than 950 TAF. In normal conditions, Roseville’s surface water diversions would be defined by the most recent UWMP’s 5- year projected demand. Roseville’s strategy in normal years is to not pump groundwater from groundwater wells in excess of what was injected, thus creating a bank of water for future use.

Dry Conditions
Dry Conditions could be defined as when the UIFR is between 950 TAF and 400 TAF. In the first Water Forum Agreement, surface water commitments during these conditions generally follow a “wedge” shape (decreasing linearly from normal levels to the driest conditions). Per Roseville’s 2020 Water Shortage Contingency Plan (WSCP), if a significant drought stage is reached, Roseville can pump additional groundwater to augment its surface water supply and make up for deficits of the surface water supply. Roseville continues to invest in development of groundwater infrastructure to increase supply reliability in times of drought, however in any given year type, Roseville must make determinations of drought stage without consideration of groundwater supplies, per the terms of the Roseville Municipal Code.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 164
In both Dry and Driest hydrological year types, Roseville committed to forego 4,460 AF of surface water in 3 out of 8 years to support the health of the LAR. The American River Terms for Ecosystem Support and Infrastructure Assistance Needs (ARTESIAN) project agreement with the Regional Water Agency (RWA) was created to govern the administration of California Department of Water Resources (DWR) funds provided to RWA on behalf of the participants for early implementation of the American River region’s 2019 Voluntary Agreement proposal.

In consideration of the funding provided by DWR under this Funding Agreement, the American River water suppliers who receive that funding agreed to jointly provide 30,000 acre-feet of groundwater- substitution water to augment, through Reclamation's operation of Folsom Dam and Reservoir as part of coordinated CVP and State Water Project (SWP) operations, stream flows in the LAR in each of three out of eight 8 years beginning in 2025. Each of those three years will be either a critical or dry year on the Sacramento Valley Index under the State Water Resources Control Board's Revised Decision 1641. This commitment is referred to as the "Flow Contribution" and each annual contribution is referred to as an "Annual Flow Contribution." Roseville, as a Participant in the RWA joint powers agreement and a recipient of grant funding, has committed to 4,460 AF.

Driest Conditions
The driest conditions are proposed to be defined as when the UIFR is 400 TAF or lower. In the driest conditions, Roseville proposes to reduce surface water diversions from Normal Diversions by 20%. This proposal is specific to surface water diversions and is not to be confused with demands. Roseville’s WSCP guides operations and demands based on expected supply availability. Per Roseville’s 2020 WSCP , if a significant drought stage is reached, Roseville can pump additional groundwater to augment its surface water supply and make up for deficits. Roseville continues to invest in development of groundwater infrastructure to increase supply reliability in times of drought, however in any given year type, Roseville must make determinations of drought stage without consideration of groundwater supplies, per the terms of the Roseville Municipal Code.

Critically Low Storage Conditions
Roseville’s sources of surface water are all delivered through a municipal and industrial (M&I) intake in Folsom Dam, which is at an elevation that would be subject to air entrainment at approximately 110,000 AF of storage in Folsom Reservoir. Because this entrainment could result in significant damage to the impellers of the pumps that Reclamation uses to pump the supplies brought through the intake to Roseville, SJWD, and the city of Folsom, this level of storage is likely to cause “dead pool” conditions, which to date, has never occurred.

If the water level drops below the M&I intake, Reclamation would use an emergency pump on one of the three power penstocks in the dam to deliver water to Roseville and SJWD and floating barges to deliver water to Folsom. The emergency pump has a capacity of 60 cfs (43,500 AF/yr), and the barges have a capacity of 30 cfs. These facilities would allow Reclamation to access water in Folsom Reservoir between the 110,000 AF at which the M&I intake goes dry and the approximately 53,000 AF storage level at which the power penstocks go dry.

To further prepare for and mitigate this possible “dead pool” scenario, below are the current and future emergency plans on how Roseville would navigate a “dead pool” scenario at Folsom Reservoir.

Additional information is provided in the Project List and Future Water Supply Reliability Efforts.

Summary of Dry Conditions Management
Roseville has strategically positioned itself to meet current and buildout water demands while enhancing supply reliability and supporting environmental stewardship of the LAR. Through a combination of diversified water sources, infrastructure investments, and collaborative regional planning, Roseville demonstrates its commitment to long-term water sustainability.

Current Demand & Supply Capacity:
• MDD: 55 MGD
• For Critically Low Storage Conditions
o With a planned 20% target demand reduction via water conservation (Revised MDD:

44.0 MGD)
• Available Supply
o Emergency pump at Folsom Reservoir: 19.4 MGD
o ASR Extraction Capacity: 16.7 MGD

43 Roseville’s Municipal Code requires water conservation levels for each drought stage; from 10% for a stage one drought and up to 50% for a stage five drought.
44 Currently, Roseville has 7 active ASR wells with a production capacity of 16.7 MGD. 45 Four additional ASR wells are planned by 2028 increasing the production capacity to 25.9 MGD of groundwater to serve to our customers’ demands under mandatory water conservation.

o Emergency interties: 17.3 MGD
o TOTAL Projected Available Supply = 19.4 + 16.7 + 17.3 = 53.4 MGD This summary reflects a supply capacity that exceeds projected demand, which Roseville plans to leverage as a key strategy for mitigating critically low storage conditions.

Buildout Demand & Supply Capacity:
• MDD: 100 MGD
• For Critically Low Storage Conditions
o With a planned 20% target demand reduction via water conservation (Revised MDD: 80 MGD)
• Available Supply
o ASR Extraction Capacity (11 wells): 25.9 MGD
o Raw Water Pipeline (MFP Supply) via PCWA: 10 MGD
o RiverArc Project: 57 MGD
o TOTAL Projected Available Supply = 25.9 + 10 + 57 = 92.9 MGD This summary, a conservative approach (without the emergency pump at Folsom, and without supply from emergency interties) reflects a supply capacity that exceeds projected demand, which Roseville plans to leverage as a key strategy for mitigating critically low storage conditions. These enhancements create resilience during critical shortage conditions such as droughts or potential “dead pool” scenarios at the Folsom Reservoir.

Through these efforts, the City of Roseville continues to be a regional leader in integrated water resource management, supporting both water supply reliability and the ecological health of the LAR.

Demand Management
Roseville understands that Water Code Section 10632 (a)(3)(A) requires purveyors to plan for reductions of 10%, 20%, 50%, and beyond. Roseville’s current Water Shortage Contingency Plan (WSCP), as approved by the City Council, stipulates a 20% reduction in demand at a Stage 2 shortage level (when annual supplies are expected to meet 80% of the expected demand). The WSCP also includes shortage levels up to Stage 5 when supplies are only projected to meet 50% of the demands. The WSCP would continue to guide Roseville’s operations and if supplies were projected to be reduced to a level requiring greater reductions, those reductions would be implemented.

To meet long-term water use targets associated with the 2024 “Making Conservation a California Way of Life” regulations and other state ordinances and ensure a sustainable supply, Roseville implements a comprehensive set of Demand Management Measures (DMMs) as outlined in its UWMP .

Core DMMs per Water Conservation Act of 2009 (Senate Bill X7-7) Requirements • Water Waste Prevention Ordinance: Enforced through patrols and public reporting to curb non- essential use.
• Metering Program: Allows for efficient usage tracking and leak detection. • Conservation Pricing: A uniform rate structure reflects true water cost and encourages efficient use.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 167
• Public Education & Outreach: Ongoing campaigns, school programs, and exhibits at the Utility Exploration Center, a facility that focuses on educating Roseville customers, promote water- saving behaviors.
• System Loss Management: Annual audits, in-house and third-party leak detection, and potable water pipeline rehabilitation projects help reduce water loss. • Program Coordination & Staffing: Certified staff manage and implement conservation programs and customer engagement initiatives.

Current Residential & Commercial Conservation Programs
• Residential: Includes Water Wise House Calls, toilet replacement rebates, turf replacement (“Cash for Grass”), irrigation rebates, and landscape water budget tracking. • Commercial: Offers irrigation budgets and surveys, customized rebates for irrigation and appliances, and interior water use audits.
• Additional Measures
o Water waste investigations
o Advanced Metering Infrastructure (AMI) program monitoring o High water use investigations
Other Ongoing Conservation Efforts
• Monthly water use reporting (SB 606 & AB 1668)
• Ban on wasteful practices (SB 606 & AB 1668)
• Leak reduction initiatives (SB 606 & AB 1668)
• Model Water Efficient Landscape Ordinance (MWELO) enforcement and annual reporting to DWR
• Developing policy for non-functional turf (AB 1572) compliance • Ongoing Roseville Municipal Code revisions to align with state water use regulations (AB 1572) • Cross-departmental collaboration to ensure compliance with non-functional turf requirements (AB 1572)
Regional Collaboration
• RWA Partnership: Continued expansion of education and awareness through the Regional Water Efficiency Program (WEP) - Roseville participates in outreach, rebates, events, and award- winning campaigns such as “Summer Strong” and “Your Weekend, Your Rules,” reaching millions across the region.

Future Plans
To continue to ensure that Roseville is meeting the goals and targets of the 2024 “Making Conservation a California Way of Life” regulations, Assembly Bill (AB) 1572 related to irrigation of non-functional turf with potable water, and the Model Water Efficient Landscape Ordinance (MWELO), the following proposed combination of strategies are future considerations. • Expand customer access to real-time water use data through AMI portal enhancements to continue to create awareness of water use and consistently influence behavior for lower water use.

• Enhance outdoor water education efforts via the Inspiration Garden for both residential customers and commercial businesses.
• Continuously adapt programs based on effectiveness, funding availability, and community needs.

Caveats and Assurances
• If, and when, the City of Roseville exercises all or part of the additional 10 TAF of PCWA water, Roseville’s PSA and all information herein will be updated upon written notice to the Water Forum.
• In circumstances where excess water is made available by Reclamation by Article 3(f) of Roseville’s Water Repayment Contract or by a Section 215 Contract between Roseville and Reclamation due to flood control operations at Folsom Reservoir, for the purposes of groundwater recharge, that water shall not be counted as diversion water within this PSA, regardless of year type.
• Future projects and investments are described in a point in time and project aspects and details may be subject to change, at Roseville’s sole discretion, to meet its water supply reliability objectives.
• Roseville and other signatories to this agreement, via the RiverArc Project, have proposed to divert water from the Sacramento River rather than diverting from the American River under certain hydrologic conditions. This would allow water to continue to flow down the LAR.

Signatories conceptually endorse this RiverArc Project, subject to environmental analysis of the impact to the Sacramento River. This RiverArc Project will require certain changes to Roseville’s CVP contract, including an additional point of diversion on the Sacramento River. Roseville’s CVP place of use is unchanged at this point in time and still remains within the limits of Roseville.

Signatories will endorse these changes to Roseville’s CVP contract subject to continued endorsement of the RiverArc Project.

Project List and Future Water Supply Reliability Efforts The following projects are key to Roseville looking out to 2040 and are designed to increase water supply reliability for Roseville and have the potential to support the Water Forum’s coequal objectives.

Additional ASR Wells
Additional construction of ASR wells, with four additional ASR wells planned to be completed by the late 2020’s or early 2030’s, which would add 9.2 MGD to Roseville’s groundwater production capacity available for emergency use; with current efforts underway to identify additional infill property that could house more ASR wells in the future. Addition of ASR wells to the service portfolio can be constrained by available land, suitable hydrogeology, and water quality. The number of additional wells, beyond the additional four planned, will be determined based on these constraints, among others.

Raw Water Pipeline
With a joint venture project between PCWA, the U.S. Army Corp of Engineers (USACE), and the City of Roseville, Roseville intends to utilize the Raw Water Pipeline to access the Roseville’s existing American River Middle Fork Project (MFP) raw water supply by constructing a direct pipeline from PCWA’s Foothill Raw Water Pipeline to Roseville’s Barton Road Water Treatment Plant (reducing reliance on the water

intake at Folsom Reservoir). Roseville anticipates earliest completion of this facility will be the late 2030’s or beyond. This project is intended as a redundant way to access already contracted MFP water supplies and mitigate the potential future risk of “dead pool” conditions at Folsom Reservoir’s intake structure where almost all Roseville’s surface water conveyance capacity is for both CVP and PCWA MFP surface water supplies.

Preliminary feasibility assessments are being conducted to evaluate future treated water capacity improvements in PCWA’s and Roseville’s systems, including shared interties to build more capacity to serve water demands to Roseville, in case there is an emergency, or in the event that Roseville experiences a constriction of water supply deliveries due to “dead pool” conditions at Folsom Reservoir.

This denotes the project in a point in time and project aspects and details may be subject to change to meet this water supply reliability objective.

Projects at Folsom Reservoir
Support water access projects at Folsom Reservoir that increase intake infrastructure redundancy and reduce the risk posed to water supplies by potential future “dead pool” conditions.

The Folsom Reservoir Raw Water Delivery Reliability Project seeks to improve the reliability of delivery of senior water rights by Reclamation pursuant to settlement contracts for CVP water from Folsom Dam to the City of Folsom, Roseville, and SJWD. These three entities (collectively, Partners) share a single municipal and industrial (M&I) water supply intake within Folsom Dam that can become inoperable because of mechanical/structural failure, disaster, or low reservoir water levels. The ARBS, recently prepared by Stantec in collaboration with Reclamation and water purveyors in the region, projected that climate change will likely worsen with associated impacts to the American River watershed, including deterioration of water supply and delivery reliability for the Partners.

The project objectives are to develop engineering alternatives to secure a reliable water delivery system from Folsom Reservoir under a wide range of hydrologic conditions and emergencies to meet the Partners’ demand requirements during:

1. Planned outages for maintenance of Reclamation facilities,

2. Unplanned outages, and

3. Low lake levels potentially occurring under drought conditions.

The Partners have been evaluating multiple alternatives for redundant intake structures and pump stations or siphons located at/or in the vicinity of the Folsom Reservoir. Additional future meetings and efforts between the stakeholders and Reclamation are necessary to arrive at the best-fit solution for the stakeholders, which would further clarify project concepts, implementation logistics, potential cost optimization, funding opportunities, and proponent responsibilities.

RiverArc Project
With investment in the RiverArc Project, Roseville intends to secure 20 MGD (22,403 AFY) of Sacramento River surface water in the 2030’s; and an additional 37 MGD (41,445 AFY) in the 2040’s, as an alternative to diverting water from the American River in dry or drought conditions. Once operational, this project

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Roseville PSA 170
could significantly reduce diversions from the American River by up to 57 MGD (63,848 AFY). This alternative CVP supply diversion will be delivered via new transmission mains to Roseville’s potable water distribution system in the western side of Roseville. The current project partners are in the very early stages of the project, developing the Environmental Impact Report (EIR) and project description.

An analysis to determine whether Sacramento River water will be available for diversion at this facility under a wide range of hydrologic conditions will be conducted as part of the CalSim modeling portion of the EIR. CalSim is the model used to simulate SWP and CVP operations. These findings from the EIR should also be incorporated into the ARCAP analysis. The final project size and scope will depend on EIR findings, project costs, and Roseville’s water reliability needs at the time of project implementation.

City of Sacramento
Purveyor Specific Agreement
Updated: December 19, 2025
The City of Sacramento (City) is committed to supporting good stewardship of the American River watershed and recommits its membership in the Water Forum as a model for this effort. The City will continue its advocacy for the health of the river through actionable, meaningful efforts supporting cold water carry-over at Folsom reservoir, the Modified Flow Management Standard (MFMS), habitat restoration efforts, a new temperature control device at Folsom, and advocacy at the federal level with our U.S. Bureau of Reclamation (Reclamation) partners to balance the Water Forum coequal objectives.

Achieving the co-equal objectives requires action every year. The City will also continue its commitment to water affordability, water efficiency and to “house” the many administrative functions of the Water Forum as a City entity to support the greater good of a healthy watershed. The Water Forum has endeavored to provide “peace on the river” while knowing that a healthy water supply is reliant upon a healthy river.

Purveyor Background
Service Area
The water system began providing service in the City in approximately 1854. Today, the City’s retail water service area covers approximately 63,182 acres within a boundary that is largely contiguous with the City limits. The Sacramento Suburban Water District (SSWD) serves a small portion of City residents and businesses on the eastern side of the City, and the water system serves a number of customers in the unincorporated portion of the County of Sacramento (County) adjacent to the service area of California American Water (Cal Am). The population within both areas is roughly equivalent. The City wholesales water to Cal Am, SSWD, Natomas Unified School District (NUSD), and Sacramento County Water Agency (SCWA) for service to Sacramento International Airport and Metro Air Park, a 1,320-acre business park, and wheels water to the SCWA for the South Sacramento Zone 40 service area. The differentiation between the terms “wholesale” and “wheeling” are a function of water rights accounting. In either case, the City is treating and delivering potable water through its distribution system to those customers. In addition to SSWD, Cal Am, and SCWA, additional water agencies such as Tokay Park Water Company, Golden State Water Company, and Florin County Water District share (in whole or in part) the approved place-of-use (POU) to receive surface water from American River entitlements through potential wholesale arrangement.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Sacramento PSA 172
The City uses the same surface water treatment facilities, groundwater wells, storage tanks, pumping facilities, and distribution/transmission pipelines to deliver water to retail, wholesale, and wheeling customers. The water system operates as a single network, with supplies from one source of water being interconnected within the system to meet demands.

Water System Facilities
The water system includes two surface-water treatment facilities, groundwater wells, storage facilities, pumping facilities, and distribution/transmission pipelines. The City maintains eight metered wholesale/wheeling connections to adjacent agencies and 21 emergency interties.

Water Treatment Plants
The City treats surface water diverted from the Sacramento and American Rivers through the Sacramento River Water Treatment Plant (SRWTP), while the E.A. Fairbairn Water Treatment Plant (FWTP) treats surface water diverted from the American River.

Sacramento River Water Treatment Plant
Water diversion and treatment from what is now known as the SRWTP began in the early 1900’s. By 1924, with improvements to filtration and chlorination, the capacity was 32 million gallons per day (MGD), followed by a near-term doubling to 70 MGD. The facility treats water diverted approximately one-half mile downstream of the American River confluence with the Sacramento River. A new intake structure was completed in 2004. The most recent major project in 2016 returned SRWTP peak capacity to 160 MGD. The project included rehabilitation and replacement work on the sedimentation basins, high-service pump station, filters, solid dewatering facilities, and electrical switchgear. Operation of SRWTP at 160 MGD is limited to the period from May 15 to September 30 of each year, which includes the warmer summer months when peak capacity is needed. At other times of the year the treatment is limited to 120 MGD. The actual available capacity of SRWTP may also be adversely affected by drought conditions if low river elevations reduce the operating efficiency of supply pumps. A project to rejuvenate aging infrastructure and potentially add advanced water treatment technology to adapt to climate-induced water quality changes is being planned and environmental documentation is being developed, along with potential expansion to meet future demands.

E.A. Fairbairn Water Treatment Plant
The FWTP is located on the American River approximately seven miles upstream of the confluence of the American and Sacramento Rivers. The FWTP began operation in 1964 and has a current design capacity of 200 MGD following an expansion completed in 2005. Currently, the State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW) permitted the FWTP with a capacity of 160 MGD. The facility is further constrained by “Hodge” and “Conference year” conditions (described in greater detail later in this document) that the City agreed to in the original Water Forum Agreement and subsequently added to its binding water rights documentation with the SWRCB. Currently, pursuant to the City's capital infrastructure planning schedule, facility production is maintained at 100 MGD or below. A project to rejuvenate aging infrastructure and potentially add advanced water treatment technology to adapt to climate-induced water quality changes is currently being planned and environmental documentation is being developed.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Sacramento PSA 173
Groundwater Wells
The City currently has 22 wells permitted by DDW in the North American Subbasin and the South American Subbasin that are connected to the potable water system, with a current production capacity of approximately 5-20 MGD. The majority of these wells have been in service for 50-80 years and are nearing the end of useful life. The range in capacity is largely a function of recurring maintenance and adaptation to evolving water quality standards. Between 2015 and 2024, the City completed a groundwater infrastructure master plan and Environmental Impact Report for the systematic replacement of nearly all its well inventory. That information is incorporated into approved Groundwater Sustainability Plans in the North and South American Subbasins. Capacity and flexibility of operations is expected to change over time as facilities are replaced. These forecasted changes are also included in the relevant Groundwater Sustainability Plans and developing programs like the Sacramento Regional Water Bank.

The City maintains a policy that irrigation areas of greater than 5 acres consider utilizing non-potable irrigation wells or recycled water for dedicated irrigation purposes. Examples of this can be found at locations such as William Land Park, Sacramento Historic City Cemetery, or Bartley Cavanaugh Golf Course. A small number of City residents and businesses own and operate private wells for onsite use.

The City does not manage, test, control, or meter privately owned wells.

Additional Sources of Water
Two of the City’s previously described wholesale interties are designed to allow both the delivery of water from the City to the adjacent water agency and the receipt of potable water from those agencies to the City. Both facilities are permitted by the State of California. The first is with SSWD, which can deliver up to 17 MGD of potable groundwater to the City. The second intertie is with SCWA which can deliver up to 10 MGD of groundwater. The City would look to these facilities to support programs that leave water in the river during periods of water scarcity such as groundwater substitution transfers, leaving surface water in the ecosystem without rediversion under an agreement with the State of California, to augment City-operated supply facilities in the event of an emergency, and to support the development of more robust region-wide conjunctive use programs (e.g., Sacramento Regional Water Bank).

Surface Water Supplies
Between the City’s various surface water entitlements and agreements with other parties, the following table identifies the volumetric limits of its water supplies per City contract with Reclamation. The City also maintains a history of diverting water from the Sacramento River under “Pre-1914” entitlements, but that is exclusive to the Sacramento River. American River entitlements can be taken at the FWTP or the SRWTP facilities. The Sacramento River permit (Permit 992) and two of the four American River permits (Permits 11358 and 11361) provide for the direct diversion of water. Two of the four American River permits (Permits 11359 and 11360) provide for both direct diversion as well as rediversion of previously stored water in various reservoirs from Nimbus to the upper reaches of the American River Basin.

Independent of the Sacramento River and American River permits, the City claims and maintains a Pre- 1914 entitlement for 75 cubic feet per second (CFS) with a priority date of 1849. The POU for Pre-1914 rights is not limited in the same fashion as other City permits.

Reclamation Operating Contract
The City’s ability to use its permits for the Sacramento and American Rivers is subject to the provisions of the “Operating Contract Relating to Folsom and Nimbus Dams and Their Related Works and to Diversions of Water by the City of Sacramento,” Contract No. 14-06-200-6497, entered in 1957 by the City and Reclamation. Under the contract, the City agreed to limit its combined diversion under its American River water right permits to a maximum rate of 675 CFS, and a maximum amount that may scale up to 245,000 acre-feet (AF) a year by the year 2030. The City also agreed to limit diversion under its Sacramento River post-1914 water right permit to a maximum rate of 225 CFS and a maximum amount of 81,800 MG per year. This limits the City’s total diversions of Sacramento and American River water under the contract to 326,800 AF per year. In return, the Operating Contract requires Reclamation to operate its facilities to make enough water available in the rivers to enable the agreed-upon diversions by the City. The agreement is permanent and not subject to renewal.

Surface Water and Groundwater Management
The production facilities in the water system are interconnected and operated in a dynamic fashion. The City utilizes its various facilities to meet demands and other water resources mandates. Operational limitations to meet minimum levels of service (e.g., water pressure, water quality, fire suppression support) for customers do exist. So, while certain flexibility exists to shift between sources, it is not without limit.

Generally, the City equally balances surface water operations between the SRWTP and FWTP to optimize level of service delivery to customers and reduce the need for any one facility to operate at unusually high energy load. That said, the City has, and intends to continue, a practice of preferentially shifting from either SRWTP or FWTP to maintain the level of service needs, if one river or another is under pressure, or if raw water quality is notably different. The need to deliver clean, safe drinking water with an adequate level of service per all legal, permit, and policy direction of the Sacramento City Council will remain at the forefront of operational decisions of the water system.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Sacramento PSA 175
The City includes the instantaneous (Hodge) and annual diversion limitations (Unimpaired Inflow to Folsom Reservoir (UIFR) < 400TAF) at FWTP as part of its long-range infrastructure planning.

When conditions allow, the City will reduce overall surface water operations and preferentially shift to groundwater. Drivers for this action may be overall poor surface water hydrologic conditions, opportunities for groundwater substitution transfers that leaves surface water in the ecosystem until delivered to a downstream user, managed actions as part of the Sacramento Regional Water Bank whereby the City will extract groundwater that has previously been recharged and stored in the basin, or a recently approved set of agreements with the State of California to provide the additional surface water for ecosystem benefits without a downstream diverter. To provide a sense of scale, in the drier periods of 2018 and then 2020-2022, City water demand served by groundwater rose from a historic 15- 20% to approximately 35%. This shift benefits the achievement of the coequal objectives and all steps to expand on the ability to make this shift are a priority.

In any set of conditions that indicate a preference to shift toward groundwater, the City engages with local Groundwater Sustainability Agencies to ensure the extraction pattern (either from its own wells or through receipt of groundwater from others) is consistent with local Groundwater Sustainability Plans.

Groundwater substitution transfers and Sacramento Regional Water Bank actions require additional groundwater monitoring to ensure no other user of groundwater is impacted and to further ensure consistency with local groundwater sustainability plans.

With the Regional Water Authority as the leading voice, the City of Sacramento, along with other local purveyors, is supporting the statewide Healthy Rivers and Landscapes Proposal (HRLP) to provide increased river flows during Dry and Critically Dry periods (Sacramento Valley Index D1641) and expand habitat in the Sacramento and San Joaquin Rivers and Bay-Delta. The proposal, if approved by SWRCB, would serve as an implementation pathway for an updated Bay-Delta Plan and would present itself as a priority for the City of Sacramento. In absence of that approval, the City of Sacramento remains obligated to provide environmental flows after a series of agreements were executed in 2023 and 2024 that guarantee a shift from surface water to groundwater when called upon by the State for ecosystem benefits.

In acknowledging the potential benefits of leveraging groundwater as a resource during periods of surface water scarcity, the City also supports maintaining a sustainable groundwater basin in the North and South American Subbasins. Seeking opportunities to recharge that resource requires equal focus if groundwater is to be present when most needed. Maintaining consistency with local Groundwater Sustainability Plans and meeting the requirements of the Sustainable Groundwater Management Act present legal boundaries that the City remains cognizant of.

The City is also an active supporter and participant of the developing “Sacramento Regional Water Bank”, with the Regional Water Authority as the lead organization. The stated goals of the Water Bank program at the writing of this Purveyor Specific Agreement (PSA) are as follows:
“The GOAL of the Water Bank is to expand conjunctive use, thereby increasing water banking operations throughout the region to:
1) Improve long-term regional reliability and provide statewide water supply opportunities when possible; and

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 City of Sacramento PSA 176
2) Support healthy ecosystem function on the lower American River” Given the totality of anticipated climate change pressures on water resources, the anticipated need to respond more dynamically to hydrologic conditions, participate in opportunities to leave surface water in the ecosystem until diverted elsewhere, and to ensure the success of the recently executed agreements to make environmental water available without a downstream diverter through shifts to groundwater, the City is taking the following steps:
• Expanding the capacity of City groundwater infrastructure through a comprehensive groundwater well replacement program and identifying connections to others that can assist in leveraging groundwater as a strategic resource to enhance water supply reliability and to provide ecosystem benefits.
• Within the Hodge or Conference year constraints, ensure groundwater recharge actions are occurring in the basin to maintain readiness for the turn to groundwater in the poorer surface water conditions.

To the degree that extremes in weather from wet and cold to dry and hot presented by climate change occur, so too do the needs for flexible operations to adapt to such changing conditions.

The City anticipates future additions to surface water infrastructure. As part of the 2000 Water Forum Agreement, and the expansion of FWTP , the City also committed to the construction of other facilities such as expansion/rehabilitation of the Sacramento River Water Treatment Plant and river intake to assure that a reliable alternative supply (groundwater, pump back, and/or diversion from the Sacramento River) is available whenever it is needed. The City completed a rehabilitation project at SRWTP in 2007, which set aside land for future expansion, and has initiated environmental review for the expansion of SRWTP and other projects (see “Water+” below). Extensive evaluations on the viability of a previously contemplated “pump-back” project, which would have entailed a new intake on the Sacramento River and a large raw water pipeline connecting the new intake with FWTP have identified that project as infeasible.

Demand Management
The City’s baseline water usage per capita for the purpose of compliance with SBX 7-7 was 282 gallons- per-capita-per-day (gpcd) (years 1996-2005), with a 2020 target of 225 gpcd. At the SBX7-7 compliance date of 2020, the City customer usage was down to 169 gpcd, thereby meeting legislative mandates. For the last several years, the City has hovered around 150 gpcd. This was achieved through a variety of means including an accelerated Advanced Metering Infrastructure (AMI) metering program and expanded water conservation incentive and outreach efforts.

Moving forward, through the Long Term Water Conservation Framework legislation (SB 606 and AB 1668), the State of California has created real-time targets for water suppliers, including the City, that involve a dramatic water use reduction target over the next 15 years tied to a residential indoor water use reduction as well as a landscape water efficiency target that involves reporting on landscape water demand as compared to landscape water need as calculated by the State. This system-wide budget- based approach also includes a reduction in water suppliers’ system water loss (gallons per connection per day). To achieve these targets, the City anticipates that it will need to dramatically expand customer participation in its programs and anticipates making refinements to existing programs as well as adding programs that will achieve these requirements. An analysis and prioritization of these potential

programs is underway and engagement with Water Forum membership is ongoing. Draft and final work products will be provided to the Water Forum membership.

Current City conservation programs elements are advertised on the City web page. https://www.cityofsacramento.gov/utilities/water-conservation While subject to change as program effectiveness is evaluated, examples of likely program enhancement beyond existing include:
• Monitoring and analysis of meters dedicated solely to irrigation • High efficiency toilet retrofit programs
• Landscape rebate programs
• Enhanced leak repair incentive programs
• Enhanced water and energy partnership rebates
• Enhanced residential water surveys
Water+
https://www.cityofsacramento.gov/utilities/projects/waterplus The Department of Utilities in 2021 launched Water+, a program designed to help ensure safe, high- quality drinking water supply for customers. The program will help protect long-term drinking water reliability, resiliency to climate change, and help meet future retail and wholesale water demands of the City of Sacramento POU.

Water+ has several goals, which include:
• Improving water treatment methods to meet changing water quality in the Sacramento and American rivers as well as changing drinking water regulations. • Improving the safety and reliability of the City’s surface water treatment plants -- the E.A.

Fairbairn Water Treatment Plant and the Sacramento River Water Treatment Plant. • Providing consistent drinking water treatment and distribution to City customers. • Increasing water treatment supply and capacity to meet future water demands. • The program will replace and expand aging facilities, improve water treatment methods to be safer and more environmentally friendly, and make overall system improvements.

The first phase of Water+ includes the Treatment Plants Resiliency and Improvements Project, which will help improve the long-term safety, reliability and resiliency of the City’s water supply, and address several issues defined in the City’s 2035 General Plan.

The project will feature several water treatment improvements, including:
• Replacing aging infrastructure and facilities that are reaching the end of their useful lives • Improvements to the treatment process at both water treatment facilities • A new Sacramento River water intake structure and new pipelines to SRWTP to allow for increased future diversions and greater reliability of existing diversions • Improvements to water transmission and distribution systems near SRWTP

River Arc
Concurrent with the planned expansion of SRWTP , a group of local water agencies with the support of select Water Forum environmental members have initiated early planning for a new facility on the Sacramento River. The RiverArc Project is an ecosystem, capacity, and resiliency project that will provide significantly improved backup and flexibility to water sources available for City customers, and to surrounding communities. The project would divert water through an existing water intake structure on the Sacramento River to offset water currently planned to be diverted from Folsom Reservoir or from the American River at the Placer County Water Agency (PCWA) pumping plant near the Auburn Dam site.

Reduction of draws from the American River has been identified as a potential adaptation measure for climate change impacts to the lower American River ecosystem and water supply reliability in the American River watershed as described in the 2022 American River Basin Plan. In 2015 and 2021, Folsom Reservoir levels were very close to not being able to meet minimum municipal water supply intake elevations. The flow of the Sacramento River, which is many times the size of the American River, has the capacity to reduce reliance on the American River.

The RiverArc Project presents a more complex governance structure with multiple participating agencies, is located further from the City’s core water transmission infrastructure, requires additional staffing, and may present a reduced financial economy of scale that a SRWTP expansion could offer. However, the City recognizes the potential benefits to the region RiverArc could bring to the Water Forum coequal objectives and the potential to support the Water Forum 2050 initiative. At present, the City is focusing on RiverArc as the next diversion and treatment capacity project, ahead of a SRWTP expansion with the understanding and expectation of ongoing Water Forum signatory support.

Drier Conditions Management
In all years when the California Department of Water Resources (DWR) annual projected unimpaired runoff into Folsom Reservoir is greater than 550,000 AF, or the March through November projected unimpaired inflow into Folsom Reservoir is greater than 400,000 AF, the City may divert water at FWTP in accordance with the following criteria.

1. Diversion up to 310 cfs (200 million gallons per day [MGD]) so long as the flow bypassing the diversion at FWTP is greater than the Hodge Flow Criteria46.

Table 4. Hodge Flow Criteria
Period American River Hodge Flow Criteria, cfs
October 15 through February 2,000

City water diverted at FWTP in drier conditions in accordance with the foregoing limitations could be used anywhere within the City’s authorized POU as it exists now and in the future.

Provision for Use of FWTP Design Capacity Over 100MGD
The City added the Hodge restrictions to FWTP to its surface water entitlement in October 2010 following approval of the original Water Forum Agreement. The goal of these restrictions was to ensure adequate flow for the fishery at certain times of the year. This goal is embedded in the Flow Management Standard. The prior Water Forum effort also anticipated a potential pathway for collective support of all caucuses for the removal or amendment of these terms.

If the City and the ongoing Water Forum successor efforts agree that some combination of actions could provide a net benefit to the lower American River and allow for better use of the capacity added to FWTP (over the 100 mgd prior to the first Water Forum Agreement) in 2000, the City will have the

The implementation of the MFMS is actively planned into Reclamation’s operations and augments D893-flows as being protective measures consistent with Water Forum coequal objectives and provides an example of improved conditions.

Driest Conditions Management
In extremely dry years (i.e., years in which the DWR annual projected unimpaired inflow into Folsom Reservoir would be 550,000 acre-feet annually [AFA] or less, also referenced as the March through November projected unimpaired flow into Folsom Reservoir being less than 400,000 AF) the City would limit its diversions of city water at the FWTP to not greater than 155 cfs and not greater than 50,000 AFA.

Any additional water needs would be met by diversions at other locations and/or other sources.

City water diverted at the FWTP in extremely dry years in accordance with the foregoing limitations could be used anywhere within the City’s authorized POU as it exists now and in the future.

Critically Low Storage Conditions
In conjunction with aforementioned commitments to reduce diversions at FWTP when Hodge Flows are present (see drier year actions) or the March through November projected unimpaired flow into Folsom Reservoir being less than 400,000 AF (see driest year actions), the City will continue to support infrastructure at the FWTP intake structure that will allow operation near the low minimum flow requirement of the MFMS at 500 cfs. 500 cfs passing the FWTP is understood to correlate with the river elevation necessary to meet the minimum design of the intake pumps to avoid adverse operation. The City is committed to this balanced approach which is intended to support conservation of storage in Folsom and a minimum release pattern for ecosystem needs.

Project List
It is understood that to support the coequal objectives and mitigate challenges facing the region under future conditions, structural and non-structural projects will be needed. The City must prioritize projects that maintain the affordability of water in advancing the coequal objectives. The experience of the last couple of decades has shown that the extremes of climate change are the biggest threat to the coequal objectives and that the ability of the City to advocate for improved operations of the State and Federal projects, both internally and through local partnerships to advance conjunctive use, will be the most effective way from a cost and sustainability standpoint, to enhance the achievement of the coequal objectives. Actions can be taken in all years to improve water reliability from the most environmentally beneficial source.

Structural
The following infrastructure projects will support efforts to implement the City’s proposed PSA, and to support the coequal objectives.
• New or improved interties with other purveyors, in particular ones that promote groundwater recharge and conjunctive use and water supply reliability • Rehabilitation and modernization of existing water facilities

03/10/2026 Item No.11.

• New or expanded facilities on the Sacramento River (e.g., RiverArc or SRWTP expansion) and treatment, storage, and conveyance systems necessary to provide clean, safe, potable water • New groundwater facilities consistent with adopted groundwater sustainability plans and the City of Sacramento’s completed California Environmental Quality Act (CEQA) process to modernize its groundwater facilities
• Expanded groundwater monitoring infrastructure and data transparency platforms • Projects as defined in basin groundwater sustainability plans • Structural and Non-structural projects and programs to ensure success of the Healthy Rivers and Landscape Program (i.e., Voluntary Agreement) for the American River region or a similar tributary-specific program that improves the ecosystem, protects local existing water entitlements for participants in that program, and maintains better cold water pool conditions in Folsom and the lower American River.

Non-Structural
• Agreements with neighboring purveyors for conjunctive use opportunities and water supply reliability
• Continued water use efficiency programs and funding support for the City, including expanded relationships and/or agreements to facilitate the City’s Climate Action Plan and successful implementation of water use efficiency targets
• Water transfers consistent with groundwater sustainability plans and the California Water Code • Points of diversion on Sacramento River for City of Sacramento • Implementation of longstanding contractual agreement for water exchange between City and the Sacramento Municipal Utility District (SMUD) for SMUD’s Rancho Seco water demands • Extension and/or License of Existing Water Entitlements for the City of Sacramento • Support for identifying underground storage as a beneficial use of surface water • Changes in water rates and fees, as compliant with legal requirements to support projects consistent with the coequal objectives (e.g., water efficiency, climate change adaptation projects, and water supply reliability projects)
• Continued staffing support, when requested, for implementation of lower American River ecosystem projects (e.g., Machine Operators)
• Additional funding support from the City for science and ecosystem benefits as part of the 2024 Healthy Rivers proposal to SWRCB or a tributary-specific alternative for the American River region
• Local and Statewide advocacy for the MFMS on the lower American River and improved carryover storage within Folsom Reservoir

3. All signatories conceptually support (as defined in the Process for Project Endorsement section of the Water Forum 2050 agreement) all other structural and non-structural projects contained within this PSA and the funding and processes necessary to implement them with the exception of two non- structural projects identified above: 1) Groundwater Substitution Transfers, and 2) Implementation of contractual agreement for water exchange between City and SMUD.

4. Endorsement of water entitlements in this PSA means that signatories will expend reasonable efforts to:
a. Speak before stakeholder boards and regulatory bodies, b. Provide letters of endorsement,
c. Provide supportive comments to the media

5. The City of Sacramento acknowledges concern of some signatories that voluminous requests for endorsement for routine operational and maintenance activities could apply pressure to limited resources. The City of Sacramento does not expect to pursue full endorsement for all projects with conceptual endorsement per this PSA. The City will maintain sensitivity to fellow members’ capacity and will limit requests for full endorsement to the most impactful matters contained with this PSA and the related work of the Water Forum.

6. All signatories will support the funding of the City’s water utility operations and capital investment/reinvestment. Endorsement of funding in the context of this PSA is not intended to limit future Water Forum engagements on how rates and fees are determined within applicable laws.

7. Any solution that provides for future needs will have costs. New diversion, treatment, and distribution facilities, wells, conservation programs, and required environmental mitigation will be needed. This PSA identifies that these solutions must be equitable, fiscally responsible, and make the most efficient use of the public’s money. Prioritizing affordability of these programs and alignment with state laws surrounding appropriate use of water rate-payer dollars is supported by all signatories.

8. Water suppliers have both capital costs for facilities and operations and maintenance costs. This PSA recommends that charges imposed to recover capital costs associated with water acquisition, treatment, or delivery be equitable. Any costs for facilities funded through bonds will be recovered as provided by law. In addition, signatories to the Water Forum Agreement agree that operational, maintenance, and replacement costs should be recovered from beneficiaries of the system in accordance with California Government Code Sections 53720 to 53730 (Proposition 62) and California Constitution, Articles XIII, C and XIII, D (Proposition 218) and other laws to the extent they are applicable.

9. All parties acknowledge that language or commitments within this PSA may find themselves in conflict with other documents or regulatory proceedings/direction. Where inconsistencies occur, legally binding documents (e.g., water rights) or direction from regulatory bodies shall govern.

Additionally, the Water Forum and versions of the Water Forum 2050 Agreement do not supersede local, state, or federal boards, councils, commissions, or regulatory entities governing water suppliers, or does it present itself as a regulatory body or legally binding agreement.

East Bay Municipal Utility District
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
East Bay Municipal Utility District (EBMUD) supplies water and provides wastewater treatment for a large part of Alameda and Contra Costa counties. Based on 2010 census data and Association of Bay Area Government’s (ABAG) Projections 2040, approximately 1.4 million people are currently served by EBMUD’s water system in a 332-square-mile area extending from Crockett on the north, southward to San Lorenzo and portions of Hayward (encompassing the major cities of Oakland and Berkeley), eastward from San Francisco Bay to Walnut Creek, and south through the San Ramon Valley (including Alamo, Danville, and San Ramon). The wastewater system serves approximately 740,000 people in an 88- square-mile area of Alameda and Contra Costa counties along the Bay’s east shore, extending from Richmond in the north, southward to San Leandro. EBMUD water customers include residential, industrial, commercial, institutional, and irrigation water users. A map of EBMUD’s service area is included in Figure 1, sourced from EBMUD’s 2020 Urban Water Management Plan (UWMP).

Surface Water and Groundwater Management
Supply Portfolio
In non-drought years, EBMUD primarily serves its customers using Mokelumne River water, local runoff collected in the East Bay reservoirs (San Pablo, Upper San Leandro, and Briones), and recycled water for non-potable uses. During droughts, EBMUD’s water supplies are supplemented by diversions from the Freeport Regional Water Authority (FRWA) Intake on the Sacramento River.

Mokelumne River
The Mokelumne River serves a variety of uses, including agriculture, fisheries, hydropower, recreation, and municipal and industrial use. EBMUD has water rights that allow for delivery of up to a maximum of 325 million gallons per day (MGD) from the Mokelumne River, subject to the availability of Mokelumne River runoff and numerous flow release obligations. EBMUD’s Mokelumne River flow commitments are determined by hydrology, water rights priorities, agreements with state and federal regulatory agencies, California State Water Resources Control Board (SWRCB) orders and decisions, federal directives, court decrees, and numerous agreements between EBMUD and other Mokelumne River users, both upstream and downstream of EBMUD’s Mokelumne River facilities.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 190 To comply with the requirements of the 1998 Joint Settlement Agreement (JSA) among EBMUD, U.S. Fish and Wildlife Service (USFWS), and the California Department of Fish and Wildlife (CDFW), EBMUD continues to meet its flow commitment to protect the lower Mokelumne River by providing in-stream flow releases from EBMUD’s Camanche Dam to improve fishery conditions. The Mokelumne River provides important habitat for fall run Chinook salmon, which migrate from the ocean and reach the Mokelumne in late summer and early fall to spawn. In the spring, the juvenile salmon then migrate to the ocean, grow, and ultimately return to the Mokelumne two to three years later to spawn. Salmon spawn in the river below Camanche Dam and many also enter the Mokelumne River Fish Hatchery located at the base of EBMUD’s Camanche Dam, where eggs are collected, fertilized, incubated, and raised for release in the spring. The Mokelumne River also supports a population of Federally Threatened Central Valley Steelhead. Both the River and Hatchery support the listed population, and based on a robust science plan in recent years steelhead numbers have been trending upward, signifying successful management of the species through collaboration between EBMUD and the fish agencies.

In collaboration with the CDFW , the USFWS, and the National Marine Fisheries Service, EBMUD uses many strategies to protect and enhance Mokelumne River fisheries resources. These strategies include spawning and rearing habitat restoration, screening riparian diversions, conducting a comprehensive science program, and investing in one of the most modern and productive salmon hatcheries in the Central Valley. Additionally, Mokelumne origin salmon comprise approximately 20% to 50% annually of the recreational and commercial catch off the California Coast.

Since implementation of the JSA flow releases and temperature management practices, the Mokelumne River’s average salmon returns to the river have more than doubled from 3,636 (1940 to 1997 average) to 11,164 (1998 to 2024 average). Figure 2 shows the increase in returns of fall-run Chinook Salmon over time, with a record of over 35,000 fish in the 2024 season.

Figure 2. Returns of fall-run Chinook Salmon over time
East Bay Area Watershed and Hydrology Runoff Characteristics EBMUD’s secondary water supply source is local runoff from the East Bay area watersheds, which is stored in the terminal reservoirs within EBMUD’s service area. The availability of water from local runoff depends on two factors: hydrologic conditions and terminal reservoir storage availability. In dry and critically dry years, evaporation can exceed runoff, resulting in net loss of local supply. Local runoff supplies the East Bay, on average, 23 MGD during normal hydrologic years.

Recycled Water
EBMUD’s recycled water program has grown significantly since EBMUD began using recycled water at its Main Wastewater Treatment Plant (MWWTP) in 1971. The program has expanded to provide more recycled water to a diverse array of customers for a variety of non-potable uses. EBMUD has also worked to develop partnerships with other wastewater treatment entities to make recycled water available more broadly in its water service area. Regional partnerships like the Dublin San Ramon Services District– EBMUD Recycled Water Authority have broadened the recycled water customer base, and EBMUD has led or participated in research studies related to recycled water.

In calendar year 2020, EBMUD provided approximately 8.3 MGD of recycled water to customers for a variety of non-potable uses. Based on EBMUD’s current assumptions about which projects it is likely to implement, Table 1 (from EBMUD’s 2020 UWMP) shows the projected quantity of recycled water use by specific type for the years 2020-2045.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 196 Sustainable Groundwater Management Act (SGMA)
EBMUD has interests in two groundwater subbasins: the East Bay Plain Subbasin and the Eastern San Joaquin Groundwater Subbasin. Details are provided below.

East Bay Plain Subbasin
As a result of three legislative bills (Assembly Bill 1739, Senate Bill 1168, and Senate Bill 1319) signed into law in September 2014 and collectively known as SGMA, EBMUD initiated stakeholder outreach efforts in 2015 to identify eligible local agency interests in the formation of a Groundwater Sustainability Agency (GSA) for the East Bay Plain Subbasin. Stakeholders requested EBMUD to take the lead in SGMA compliance efforts and form a GSA as EBMUD was deemed suited to undertake the SGMA compliance responsibilities. On November 29, 2016, EBMUD became an exclusive GSA for the portion of the East Bay Plain Subbasin which underlies its service area pursuant to Water Code §10723.8(c) and (d). The City of Hayward is the GSA for the portion of the East Bay Plain Subbasin that underlies its service area.

In January 2022, EBMUD and City of Hayward collectively adopted and submitted the East Bay Plain Subbasin Groundwater Sustainability Plan (GSP), fulfilling the requirements established under SGMA.

The GSP establishes management actions that ensure the East Bay Plain Subbasin is sustainable within 20 years of implementation. EBMUD and the City of Hayward are responsible for implementing the GSP management actions.

Eastern San Joaquin (ESJ) Groundwater Subbasin
EBMUD and partners in Eastern San Joaquin County completed the DREAM Pilot Project, a pilot groundwater banking project, to determine whether a larger groundwater banking project is feasible in the ESJ Subbasin. A larger groundwater banking project has been identified in the ESJ Groundwater Sustainability Plan as a Potential Project to achieve groundwater sustainability.

Groundwater Banking
Groundwater banking efforts are currently focused in Eastern San Joaquin County where the DREAM Pilot Project was located.

The DREAM Pilot Project provided North San Joaquin Water Conservation District (NSJWCD) with up to 1,000 AF of EBMUD surface water from the Mokelumne River that participating landowners used for irrigation in lieu of pumping groundwater from the ESJ Subbasin; thereby, storing groundwater for future use. During dry years, EBMUD could recover up to half of the banked groundwater for use within its service area. The DREAM Pilot Project provided multiple benefits, including replenishment of the critically-over drafted ESJ Subbasin and dry year supplemental water supply for EBMUD. See Figure 3 for a visual depiction of the DREAM Pilot Project.

Pending further evaluation of the results of the DREAM Pilot Project and planning level evaluation for an expanded groundwater banking project, EBMUD, NSJCWCD, San Joaquin County, and the Eastern Water Alliance may pursue a larger, longer-term groundwater banking project. The expanded project capacity is currently planned for EBMUD to deliver up to 3 to 8 TAF Mokelumne River water to project partners for recharge depending on EBMUD water supply conditions. Due to the project location, the American River watershed is not anticipated to be impacted by the expanded project.

Demand Management
EBMUD commits to meeting the current conservation and water use efficiency regulations, which include the 2024 “Making Conservation a California Way of Life” regulations, Assembly Bill (AB) 1572 related to irrigation of non-functional turf with potable water, and the Model Water Efficient Landscape Ordinance (MWELO) which encourages low-water use and native landscaping for new development.

EBMUD will meet the aforementioned requirements by continuing to implement a combination of customer education, incentive programs, and efficiency improvements.

The Water Conservation Strategic Plan will guide EBMUD over the next few decades to encourage water conservation and invest in solutions which boost water conservation. The key components of its demand management portfolio are:
• Supply Side Conservation (leak detection, water loss reduction, pressure management, replace leaky pipes)
• Water Management Services (Online water consumption portal for customers, water budget reports, single family and multi-family housing consultations, WaterSmart certifications, and more)

• Rebates and Incentives (low-flow plumbing hardware, landscape conversion, irrigation equipment, flowmeters, grey-water, landscape design assistance grant, mulch coupons, custom rebates for large projects)
• Education and Outreach (EBMUD website education materials, marketing, community events, WaterSmart Gardener program and demonstration garden grants, K-12 classroom materials) The estimated water conservation through 2050 by implementing the Water Conservation Strategic Plan is shown below in Figure 4.

Figure 4. Forecasted EBMUD Water Conservation (Million Gallons per Day) Climate Change
EBMUD recognizes climate change is a growing threat to the reliability of water resources. In preparation for the future uncertainties associated with climate change, EBMUD has undertaken a rigorous evaluation of potential impacts.

EBMUD continually considers climate change impacts and takes actions to understand, mitigate, and adapt to those impacts. EBMUD maintains a Climate Change Monitoring and Response Plan (CCMRP) to inform planning efforts for future water supply, water quality, and infrastructure, and to support water and wastewater infrastructure investment decisions. Assessments were made to identify potential impacts to EBMUD in the areas of water supply and demand, water quality and the environment, flood control management, infrastructures, and energy:
• In water supply, decreased runoff and timing of runoff poses impacts to carryover storage.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 199 • Water demand and usage could increase as a result of warmer climate, as well as result in increased frequency of rationing due to water supply shortages. • Water quality could decrease as a result of warmer air temperatures shifting in spring runoff, and increasing peak runoff. Managing cold water pool levels in Camanche and Pardee Reservoirs becomes more challenging with more frequent dry water year types and warming rivers and reservoirs. Any modifications to temperatures in the river could lead to impacts to fisheries. • Rising sea levels could lead to increase in storm surge flood events, thereby posing challenges for flood control management due to the timing of the runoff and increased peak runoff. Sea level rise could damage infrastructure in the Delta and near the shore; primary concerns for EBMUD include the potential inundation of the Mokelumne Aqueducts from levee failure/overtopping in the Delta.
• Lastly, climate change could negatively affect hydropower generation as a result of changes in runoff timing and patterns, and management of cold water pool. The electricity transmission lines could lose transmitting capacity in high air temperatures, and there is an increase in the probability of wildfire exposure for some major transmission lines.

Managing Severe Droughts
EBMUD’s Drought Management Program (DMP) provides a framework to manage customer demand and pursue a diversified portfolio to reach a goal of providing 85-percent reliability for customers in EBMUD’s service area while continuing to meet all stream flow obligations on the lower Mokelumne River. The DMP guided EBMUD in managing demand and supply during the 2014-2016 and 2020-2022 droughts when mandatory and voluntary rationing was imposed, and water supplies were limited. During both the 2014-2016 and 2020-2022 droughts, EBMUD faced unanticipated constraints and updated and implemented measures to assist with demand and supply management. The DMP was revised to reflect lessons learned and actions that were taken.

The triggers to implement water shortage response action are defined by the Total System Storage (TSS) as illustrated in Figure 5. Table 6 shows the types of programs and actions that EBMUD might undertake at each stage of drought.

Note:

This table is based on the Drought Management Program adopted by EBMUD’s Board of Directors on 06/22/2021 and revised on 07/01/2025. EBMUD may revise the DMP elements from time to time.

The availability of water to EBMUD may be impacted depending on the nature of an emergency. In such cases, EBMUD would determine the applicable shortage response actions with reference to its Water Shortage Contingency Plan.

For example, the shortfall in Year 3 of a drought at 2050 demands as presented earlier in the Supply & Demand Assessment results on Table 5 would be mitigated by a combination of water transfers, San Joaquin County groundwater banking (potential expanded DREAM project), and future non- potable/potable reuse. This is in addition to demand rationing and EBMUD's CVP contract. EBMUD is

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 202 currently updating the Need for Water as part of the 2025 Urban Water Management Plan. Updates to this PSA document will be made as needed during the Water Forum 2050 comprehensive 5-year reviews.

Water Code Section 10632 requires water shortage contingency plans to provide water supply shortage levels at 10, 20, 30, 40, 50, and >50 percent thresholds. Urban water suppliers with existing water shortage contingency plans may meet this requirement by cross-referencing the water utility’s existing water shortage stages to the State of California’s six standard water shortage levels. In general, EBMUD brings in supplemental supply water and requests customers to reduce demand when the total operational storage is reduced by almost one-third. Table 7 presents EBMUD's water shortage levels cross-referenced with the State’s new standardized water shortage levels. EBMUD's water shortage levels for this cross-referencing are determined by the total operational storage available.

Table 7. Shortage Levels Cross-Referenced With State’s Shortage Stages

It is difficult to quantify the reduction in gap between supplies and demand due to the implementation of the response actions as outlined in Table 6. The response actions would be adjusted based on the level of rationing that is achieved and to meet EBMUD's policy of providing 85% reliability to its customers. At each stage, EBMUD will consider augmenting its supplies as outlined in Figure 5 with the quantities determined based on antecedent conditions and projected demand. The response actions to close the gap between supply and demand as well as the augmented supplies needed that year are outlined in the annual water supply availability assessments.

EBMUD CVP Contract
In years when EBMUD is authorized to take water under the terms of its CVP contract, which is limited only to specified water storage conditions, Reclamation allocates the water in the same manner as it does for other north-of-Delta American River Division municipal and industrial contractors. Like other CVP contractors, EBMUD’s service area is included within the consolidated place of use for all the CVP

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 203 water rights. EBMUD is willing to discuss this matter further during the American River Climate Adaptation Program process if requested by the Environmental Caucus.

Management and Protection of the Mokelumne River
As part of its Strategic Plan, EBMUD has committed to manage the Mokelumne and East Bay watersheds to ensure a high-quality water supply and protect natural resources while providing appropriate public access. EBMUD has several ongoing and planned actions to meet this goal, including Mokelumne River water temperature management, EBMUD’s pending Healthy Rivers and Landscapes (HRL) proposal, and forestry health work with the Upper Mokelumne River Watershed Authority (UMRWA).

Existing Water Temperature Management
The JSA includes a provision for cold water management to support downstream temperatures. It requires EBMUD to use its best efforts to maintain Pardee and Camanche Reservoir stratification with a minimum of 28,000 acre-feet of hypolimnetic volume (the volume of water colder than 16.4℃) in Camanche Reservoir through October, whenever Pardee Reservoir volume exceeds 100,000 acre-feet.

This provision for temperature management necessitates adaptive, flexible operations of both Pardee and Camanche reservoirs.

This water temperature requirement and other water quality requirements were established to support fall run Chinook salmon and Steelhead in the Mokelumne River during the critical fall spawning and incubation period. To manage the system to achieve that volume, or a comparable adaptive approach to ensure cold water for salmon in the fall, there are multiple actions that EBMUD can take. These include the following:
• Joint operation of Pardee and Camanche reservoir releases to maximize cold water transfer efficiency from Pardee to Camanche and minimize cold water losses within the system • Releasing warmer surface water from the Camanche Reservoir high level outlet in place of cold water releases from the bottom of the reservoir when acceptable downstream (typically April through September) to conserve cold water for fall
• Minimizing cold water diversions into the Pardee Reservoir Tower (which serves the aqueducts to the service area) to preserve cold water in Pardee for supporting the downstream cold-water pool in Camanche Reservoir
Mokelumne River HRL Flow Proposal
The goal of the Mokelumne River HRL Flow Proposal is to build on the JSA successes in the Lower Mokelumne River through a mix of flow and non-flow measures that benefit anadromous fish. If the EBMUD HRL Flow Proposal is accepted by the SWRCB, spring flow contributions will be increased without any significant effect on Camanche Reservoir release temperatures.

The Mokelumne HRL Flow Proposal was developed to provide biologically beneficial flow regimes below Camanche Dam based on ambient conditions and when those flows are most beneficial to Mokelumne River fisheries. The proposal provides that the entirety of the obligated block flow (except in offramp years) will be released during the designated year. The Mokelumne River Proposal anticipates 70 to 90 percent of full annual volume to be released in the March through May period for fry and juvenile

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 204 rearing and outmigration, and 10 to 30 percent to be released in October for adult migration, spawning, and incubation.

In summary, the Mokelumne River HRL flow proposal has been designed to build on the substantial fishery benefits achieved with the JSA over the past 26 years, providing enhanced ecosystem conditions through a combination of flow and non-flow measures while maintaining the ability to manage temperatures in the Lower Mokelumne River.

Mokelumne River HRL Non-Flow Proposal
If EBMUD’s HRL proposal is accepted by the SWRCB, 25 acres of new floodplain rearing habitat enhancement measures will be created. In addition, EBMUD has committed to the annual maintenance of a restored 1-mile (15 acres) spawning reach. No designated spawning habitat is required under minimum required habitat goals, but EBMUD has implemented 1.27 acres of new spawning habitat and

2.67 acres of maintenance of existing habitat as early implementation actions and will continue to implement habitat improvements above the minimum required as landowner and funding opportunities allow. One acre of suitable instream rearing habitat will be implemented through screening diversions and providing habitat complexity during spawning habitat restoration work. Habitat enhancement measures will be implemented in accordance with the design criteria established for habitat restoration projects under the HRL Non-Flow initiatives, as outlined in Table 15 in the Water Quality Control Plan for the San Francisco Bay/Sacramento–San Joaquin Delta Watershed (CSWRCB, 2025).

Watershed Forestry Health
EBMUD and its partners in UMRWA are implementing forest health projects that improve wildfire resiliency and protect water quality, particularly in areas along roadways where wildfires are most likely to ignite. Catastrophic wildfires in the Mokelumne Watershed would significantly impact the quality and reliability of EBMUD’s supply. Forest thinning, meadow restoration, and related projects reduce that threat.

UMRWA is a Joint Powers Authority comprised of six water agencies and three counties working collaboratively to address natural resource issues in the Upper Mokelumne watershed in Alpine, Amador, and Calaveras counties. UMRWA was formed in 2000. Over its 25-year existence, UMRWA has facilitated solutions to a variety of water, forest, and associated watershed issues. Since 2011, UMRWA has secured and administered nearly $40M in state and federal grants for water and forest projects in the watershed.

UMRWA is currently seeking a contractor for the El Dorado National Forest Projects Plan–Phase 1. The Forest Projects Plan–Phase 1 is a 25,671-acre timber stand and wildlife habitat improvement and protection project located on lands administered by the Eldorado National Forest (ENF) Amador Ranger District, within the upper Mokelumne and South Fork American River watersheds. The Phase 1 project is designed to help prevent high-intensity, large-scale wildfires, improve forest conditions, and protect important wildlife habitat and other resources. Non-commercial actions to reduce forest fuels are presently underway on 7,900 acres within the Phase 1 project area. The 11,695 +/- Phase 1 acres remaining to be treated are shown in Pending Projects Map, Forest Projects Plan–Phase 1. UMRWA has an annual fuel treatment goal of 4,000 acres per year.

Water Forum Agreement 2050
February 2026 East Bay Municipal Utility District PSA 205 Historical EBMUD Contributions to the Co-Equal Objectives Although EBMUD would be a new signatory to the Water Forum Agreement, EBMUD has financially contributed to the success of the co-equal objectives. The investment and continued partnership with Sacramento County Water Agency in the FRWA intake on the Sacramento River and accompanying Folsom South Canal Connection (FSCC) system was a significant investment to convey EBMUD’s supplemental supplies. In total, EBMUD spent approximately $500 million to construct the FRWA/FSCC systems. The FRWA intake is located downstream of the American River confluence and, when opportunities arise, allows for American River water to be diverted after it has traveled the full distance of the Lower American River (LAR), thus providing potential benefits for LAR corridor health.

EBMUD has also been an integral partner to PCWA’s PSA by purchasing the Water Forum releases during dry years. PCWA’s releases to the LAR provide both flow and temperature benefits to anadromous fish during the late summer/fall months of the driest years when the flows are most important to fish survival. Since EBMUD and PCWA began their partnership in 2013, EBMUD has purchased approximately 37 TAF for $20.4 million from PCWA.

In addition to EBMUD’s specific investments, EBMUD has indirectly supported LAR habitat enhancement through contributions to the Central Valley Project Improvement Act (CVPIA) Restoration Fund. Since 2013, EBMUD has contributed approximately $1.8 million to the CVPIA Restoration Fund.

EBMUD Surface Water Framework
This section summarizes the EBMUD proposal for Water Forum 2050 commitments related to surface water diversions in terms of their contributions to the coequal objectives and proposed investments (Projects).

Contributions to River Corridor Health
• Minimize direct surface water diversions on the LAR by taking water at Freeport. o EBMUD’s intake facility at the Freeport project offers a unique opportunity in dry years.

When water resources are scarce, and other purveyors may be letting water flow down the American River for out-of-basin transfers and/or relying more heavily on groundwater resources, EBMUD can continue to take water at Freeport to alleviate drought conditions while also allowing surface water to provide flow and temperature benefits for the LAR.
• Contribute to the CVPIA Restoration Fund pursuant to EBMUD’s CVP contract ($1.8 million to date).
• Long-term commitment, pursuant to contract between PCWA and EBMUD, to purchase PCWA Water Forum releases intended for the flow and temperature benefit of the LAR during dry years.

El Dorado Irrigation District
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
El Dorado Irrigation District (District) provides water, sewer, recycled water, and water-related recreation services within its service area. The District is the major water supplier located on the western slope of the Sierra Nevada Mountains in El Dorado County. The contiguous service area of the District spans approximately 220 square miles and includes a variety of urban, suburban, and rural communities and land uses. The population of the District’s service area is approximately 130,000, accounting for approximately two thirds of the total population of El Dorado County.

The District operates over 1,119 miles of water pipe, 27 miles of ditches, 5 water treatment plants (WTP), 4 sewage treatment facilities, 456 miles of sewer lines, 60 lift stations, 36 water and 5 recycled water storage and regulating reservoirs, and 38 water and 5 recycled water pump stations. The District’s WTPs have a total treatment capacity of approximately 102.6 million gallons per day (mgd).

The District also owns and operates a 21-megawatt hydroelectric generation project (Project 184) licensed by the Federal Energy Regulatory Commission (FERC) which consists of 4 reservoirs (Echo Lake, Lake Aloha, Caples Lake, and Silver Lake), dams, a forebay, a penstock, a powerhouse, and approximately 22 miles of flumes, canals, siphons, and tunnels located in the Sierra Nevada Mountains east of Placerville in the counties of El Dorado, Alpine, and Amador. The District acquired this hydroelectric generation project from Pacific Gas and Electric Company (PG&E) in 1999. The District operates the hydroelectric generation facilities, including recreational features, incidental to delivery of water and sells the generated power on the wholesale market. While the District generates revenue from operating Project 184, the project was purchased primarily to preserve the pre-1914 water rights associated with the facilities and to facilitate the acquisition of additional water rights thereafter obtained by Permit 21112 (described in more detail below).

Water Supply
The District’s primary supplies come from tributaries to the American and Cosumnes Rivers as described below.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 209
Jenkinson Lake
The District owns, operates, and supplies water from Jenkinson Lake through licensed appropriative water rights on Camp and Sly Park Creeks, both tributaries to the North Fork Cosumnes River. The available consumptive supply from Jenkinson Lake is approximately 23,000 acre-feet annually.

Folsom Reservoir
Pursuant to a permanent repayment contract between the District and the United States Bureau of Reclamation (USBR) (the Folsom Reservoir Repayment Contract), the District can divert up to 7,550 acre- feet per year of Central Valley Project water from Folsom Reservoir to serve the El Dorado Hills and western Cameron Park area. Additionally, in August 2010, the District and USBR executed a long-term Warren Act Contract (the Ditch/Weber Warren Act Contract) to enable the District to utilize up to 4,560 acre-feet of water per year at Folsom Reservoir from four pre-1914 water rights formerly associated with historic District ditches.

The District also has an appropriative water right (Permit 21112) to make consumptive use of 17,000 acre-feet annually of the water previously used only for Project 184’s hydroelectric power operations.

Pursuant to this right, water may be taken from Folsom Reservoir. On August 3, 2016, the District and USBR finalized and signed a long-term Warren Act Contract for use of the full 17,000 acre-feet until 2030, after which the contract is eligible for renewal.

Finally, pursuant to Public Law 101-514 (enacted in 1992), El Dorado County Water Agency (EDCWA) and USBR signed a long-term water service contract on October 23, 2019, for 15,000 acre-feet per year of water from Folsom Reservoir. Though the District and EDCWA have not yet negotiated a contract that will enable the District to utilize this supply, the District expects that, pursuant to a prior contract with the EDCWA, the District will receive at least one-half, or 7,500 acre-feet, of the water subject to future negotiation of repayment costs. This contract entitlement, if secured, will be in addition to the current Folsom Reservoir Repayment Contract entitlement of 7,550 acre-feet of water, the Ditch/Weber Warren Act Contract entitlement of 4,560 acre-feet of water, and the Permit 21112 Warren Act Contract entitlement of 17,000 acre-feet of water.

Forebay Reservoir
Forebay Reservoir is part of Project 184. Water stored in Silver, Caples, and Echo lakes and Lake Aloha is released and then diverted, along with natural river flows, into the El Dorado Canal near Kyburz and Highway 50. The El Dorado Canal conveys up to 165 cubic feet per second (cfs) approximately 22.5 miles to Forebay Reservoir in Pollock Pines. At the Forebay Reservoir, the District diverts up to 15,080 acre-feet per year for drinking water treatment at Reservoir 1 WTP .47 The balance of the flows entering Forebay Reservoir is utilized for power generation at Project 184’s El Dorado Powerhouse.

Crawford Ditch
The District has pre-1914 water rights to 5,000 acre-feet of water annually from both the North Fork Cosumnes River and Clear Creek points of diversion into the Crawford Ditch, a Gold Rush era ditch.

47 The District also delivers some water originating in the District’s Project 184 facilities into Jenkinson Lake via its Hazel Creek Tunnel.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 210
Water from Crawford Ditch is available only as raw water for irrigation and agricultural customers located along the Crawford Ditch and none of this supplemental supply is included in the District’s system firm yield water supply calculations.

In 2021, the calculated system firm yield from the first three of the sources of water supply described above totaled 63,500 acre-feet. Current surface water entitlements from both the American River and Cosumnes River total around 81,500 acre-feet, with 44,200 acre-feet originating in the American River and its tributaries.

The District has no interties with surrounding purveyors although the District’s connectivity to Folsom Reservoir provides connection to other purveyors that receive Folsom Reservoir supplies. The District does, however, have multiple interties between the American and Cosumnes basins internal to both the District’s raw water intake system and treated water distribution system.

The District currently does not use groundwater as a source of supply, nor does it overlie any groundwater basins identified by DWR Bulletin 118. Given the lack of any groundwater basins on the western slope of El Dorado County, it is extremely unlikely that the District will ever utilize groundwater as a supply in the future. While the District remains open to considering opportunities for conjunctive use projects within or outside of its service area, no such projects have been identified at this time.

However, the District is participating in the Regional Water Authority’s Sacramento Groundwater Bank.

The District also has a recycled water system with source water from two regional wastewater treatment plants that operate with an annual production rate of approximately 3,500 acre-feet. The District has used recycled water to meet non-potable demands such as industrial processes and irrigation of golf courses, landscaping, outdoor residential irrigation, and road medians within the El Dorado Hills service area. Potable water has been used to supplement the recycled water system since 2002 to meet peak demands. Construction of seasonal storage for recycled water would reduce or eliminate the need to supplement the recycled system with potable water, but the estimated costs to construct seasonal storage make it infeasible at this time.

Surface Water Management
Current and Projected Demands
The District has invested in long-term water efficiency efforts that have kept water demands relatively stable despite population growth in El Dorado County. Current District demands are on average approximately 35 thousand acre-feet (TAF) annually. This is down from approximately 45 TAF in 2008 but demands are expected to return to approximately 40 TAF by 2045. See Figure 1, below, for historic District diversions from both the American River and Cosumnes River to meet customer potable demand at WTPs.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 211

Figure 1. District American River and Cosumnes River Diversions to Meet Customer Potable Demand The percentage of water demands met by the American River or Cosumnes River supplies described above varies with hydrologic conditions and the operational constraints of the District’s water delivery system. Recent hydrologic modeling indicates that hydrologic conditions affecting Cosumnes River supplies during dry and critically dry water years will limit the District’s ability to meet increased customer water demands through increased reliance on Cosumnes River supplies. During such dry conditions with future water demands, the District proportional reliance on American River supplies may increase if Cosumnes River supplies are inadequate. As described in more detail below, there may be opportunities for the District to shift from one source of supply (i.e., American River) to another (i.e., Cosumnes River) during certain times to help meet the Water Forum’s coequal objectives.

Notably, the District has invested heavily over the last decade in infrastructure improvements that help meet the Water Forum’s coequal objectives. Examples include the $50-million construction of a temperature control device at the District’s Folsom Lake intake, the $25-million piping of an open and unlined ditch, and the recently awarded $50-million contract to construct the Sly Park Intertie pipeline between the District’s two primary supply sources on the American and Cosumnes Rivers.

El Dorado Irrigation District Surface Water Management Proposal In service to the Water Forum’s coequal objectives, and subject to all of the terms and conditions of the Water Forum 2050 agreement, including the caveats and assurances described herein, the District offers the following proposal. Commitments are discussed generally and in four different sections specific to:
• Normal (Most) and wet conditions
• Drier conditions
• Driest conditions
• Critically Low Folsom Reservoir Storage conditions
This proposal was prepared with the following guiding principles in mind:

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 212

1. Reduce surface water diversions from the Lower American River (LAR) in dry conditions to provide for river health.

2. Prioritize surface water diversions in wet conditions to allow groundwater recharge.

As presented in detail above, the District meets customer demand with supplies deriving from both the American River and Cosumnes River watersheds. Consistent with the guiding principles listed above, the District will reduce surface water diversions from the American River in dry conditions by adhering to its then-adopted Drought Action Plan and Water Shortage Contingency Plan. The Drought Action Plan includes specific actions for the management of the District’s water supply and demand, addresses the impacts associated with drought, and facilitates the timely implementation of effective drought responses. When and to the greatest extent possible, the District will rely upon Cosumnes River supplies to meet customer demand.

The District does not have access to groundwater and is, therefore, unable to substitute surface water diversions with groundwater extraction in times of surface water scarcity. However, as an operator of reservoirs upstream of Folsom Reservoir, the District is capable of releasing water from storage in Normal (Most) and Wet years for affordable transfer to LAR purveyors, which would allow purveyors that would otherwise need groundwater to forgo groundwater pumping in wet years and thereby promote groundwater recharge. The District is also able to provide additional transfer water in Drier and Driest years – amounts subject to hydrologic conditions and potential curtailments to District entitlements. The District is currently participating in the Regional Water Authority’s Sacramento Groundwater Bank and through that venue will seek partnerships with LAR purveyors for the transfers described above.

Normal (Most) and Wet Conditions Management
In normal (most) and wet conditions, the District will use American River supplies to meet up to 50% of its forecasted 5-year total potable demand and potentially provide transfer water for conjunctive use to improve groundwater conditions.
• Normal conditions exist when the forecasted unimpaired inflow into Folsom Reservoir (UIFR) is greater than 950 TAF.
• Wet conditions exist when the forecasted UIFR is greater than 1.6 MAF.

In normal and wet conditions, the District’s surface water diversions would be defined by the forecasted 5-year total potable demand in the most recent Urban Water Management Plan (UWMP). Because the District meets customer demand from both the American and Cosumnes River supplies, the forecasted total potable demand must be reduced to account for only the diversions from the American River. The reduction would be informed by recent diversion patterns in the preceding 10-year period with the maximum single-year ratio of demands met with American River supplies being applied to normal conditions (up to 50%). This 10-year maximum ratio of demand met by American River supplies would be applied to the UWMP forecasted 5-year total potable demand.

Below is a theoretical example:
• UWMP Forecasted 5-year Total Potable Demand: 40 TAF
• 10-year maximum ratio of American River-derived supplies to meet demand: 50% • Total American River Surface Water Diversions: 40 TAF * 0.50 = 20 TAF

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 213
In addition to the commitments for surface water diversions in normal and wet conditions, the District proposes to provide transfer water to LAR purveyors when the UIFR is above 950 TAF and supplies allow.

The transfer of water could improve groundwater conditions in the lower reaches of the watershed through direct groundwater recharge or wheeling of water to users that are traditionally served by groundwater in these year types.

Drier Conditions Management
In drier conditions, the District will implement the conservation measures required by its adopted Drought Action Plan, limit use of American River supplies to meet up to 70% of UWMP forecasted 5-year total potable demand, and potentially provide transfer water for conjunctive use to improve groundwater conditions.
• Drier conditions exist when the forecasted UIFR is between 400 TAF and 950 TAF.

In drier conditions, the proportion of diversions from the American River will increase relative to normal and wet conditions due to limited Cosumnes River supplies. Instead of surface water diversion reductions, the District proposes to provide downstream benefits through the reoperation and transfer of stored supplies and entitlements to LAR purveyors. The quantity of water available in drier conditions will be dependent on watershed conditions and reservoir storage. The commitment of potential volumes available for transfer to LAR purveyors or south of the Sacramento-San Joaquin Delta (south-of-Delta) demand and the source of this water can be defined at a later stage.

Driest Conditions Management
In driest conditions, the District will implement the conservation measures required by its adopted Drought Action Plan, limit use of American River Supplies to meet up to 75% of forecasted 5-year total potable demand, and potentially provide transfer water for conjunctive use to improve groundwater conditions.
• Driest conditions exist when the forecasted UIFR is less than 400 TAF.

In driest conditions, the proportion of diversions from the American River will increase relative to drier, normal, and wet conditions due to increasingly limited Cosumnes River supplies. Instead of surface water diversion reductions, the District proposes to provide downstream benefits through the reoperation and transfer of stored supplies and entitlements to LAR purveyors. The quantity of water available in driest conditions will be dependent on watershed conditions and reservoir storage. The commitment of potential volumes available for transfer to LAR purveyors or south-of-Delta demand and the source of this water can be defined at a later stage.

Critically Low Storage Conditions in Folsom Reservoir
Climate change is expected to greatly increase the frequency of critically low storage in Folsom Reservoir.

Below characterizes potential District operations that might help the American River under the following two conditions:

1. Potential operations in spring and summer when Folsom Reservoir storage is forecasted to reach 110 TAF at some point in the calendar year:
• Rely on Cosumnes River supplies to meet customer demand to the greatest extent possible

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 El Dorado Irrigation District PSA 214
• Conserve water as described in the District's Drought Action Plan • Potentially provide transfer water stored higher in the watershed • Plan for the potential installation of temporary barge and pumps at Folsom Lake

2. Potential operations in summer and fall when Folsom Storage is below 110 TAF:
• Rely on Cosumnes River supplies to meet customer demand to the greatest extent possible
• Conserve water as described in the District's Drought Action Plan • Potentially provide transfer water stored higher in the watershed • Potentially install temporary barge and pumps at Folsom Lake Demand Management
As noted above, the District invested in long-term water efficiency efforts that successfully reduced demands notwithstanding population growth within its service area. Current District demands are on average approximately 23% lower than the peak demand of 45,000 acre-feet in 2008.

In 2019, the District converted its Main Ditch into an underground pipeline, at a cost of approximately $20 million, to reduce system water losses. That project resulted in annual savings of approximately 1,500 acre-feet of water from seepage and evaporation. The District successfully defended a lawsuit brought by local opposition under the California Environmental Quality Act—see Save the El Dorado Canal v. El Dorado Irrigation District (2022) 75 Cal.App.5th 239 (upholding El Dorado Irrigation District’s Environmental Impact Report and denying the petition for writ of mandate).

The District’s Office of Water Efficiency offers several programs and services to commercial and residential customers to help conserve and achieve higher water efficiency. For example, District water efficiency staff perform water audits for homes and businesses to evaluate irrigation systems, plumbing retrofits, and detect system leaks. The District also offers rebates for qualifying purchases of water- efficient appliances.

The District is committed to abiding by current and future relevant conservation and water use efficiency regulations. At the time of signing the Water Forum 2050 agreement, key requirements are associated with the following: 2024 Making Conservation a California Way of Life regulations, Assembly Bill 1572 related to irrigation of non-functional turf with potable water, and the Model Water Efficient Landscape Ordinance (MWELO) which encourages low-water use and native landscaping for new development.

The District’s anticipated approach to comply with current water conservation efforts remains under development. On September 22, 2025, the District awarded a contract to Hoch Consulting to assist the District in developing a compliance and reporting plan to implement the Making Conservation a California Way of Life regulation. The approach will be guided by input from District staff, members of the communities we serve, and regional partners through the Water Forum. A similar process will be employed to roll out programs and actions to meet future regulatory calls for conservation. District staff will leverage the Water Forum to engage and update the region as progress is made.

Contributions to River Corridor Health
To contribute to the co-equal goal of river corridor health, the District will take the following actions:
• Release water below District reservoirs (Lake Aloha, Caples Lake, Silver Lake on the South Fork American River and Jenkinson Lake on the Cosumnes River) that provide downstream benefits to aquatic resources year-round. On the South Fork American River and its tributaries, the District’s minimum instream releases are set forth in its FERC license for Project 184 and streamflow is measured at USGS reviewed gaging stations. On the Cosumnes River, minimum instream releases are included in the District’s licensed water rights for Camp and Sly Park Creeks. Bypass flows are maintained through an 8” pipe at the Camp Creek diversion dam and release requirements to Sly Park Creek below Sly Park Dam (Jenkinson Lake) are maintained and measured by the District. The instream releases described above in both the American River and Cosumnes River are ongoing and will continue to promote and protect watershed health. • Conserve water as described in the District's Drought Action Plan to increase instream flows both above and below Folsom Reservoir.
• Make payments to the Central Valley Project (CVP) Restoration Fund. As conditions under its CVP contract, and as a requirement to divert water from Jenkinson Lake (previously considered a CVP facility), the District pays a per-acre foot restoration fee, as authorized by the Central Valley Project Improvement Act. Annual payments depend on hydrology and customer demand in any given year. In 2023, the District paid over $500,000 in restoration payments to USBR. • Release additional water from storage for instream flow as part of the American River Tributary portion of the proposed Intra-Tributary Agreement to Implement Healthy Rivers and Landscapes, an alternative to the unimpaired flow approach recommended by the State Water Resources Control Board in the proceedings to update Bay-Delta Water Quality Control Plan. • Operate its Folsom Lake intake to maximize the benefit of its temperature control device, diverting water above 60 degrees Fahrenheit while USBR is managing the cold-water pool (which may occur annually April through November, depending on conditions). • Rely on Cosumnes River supplies to meet customer demand to the greatest extent possible, effectively reducing surface water diversions from Folsom Reservoir and the South Fork American River.
• Pursue a feasible alternate supply for customers served by upper Crawford Ditch. Presently, the District diverts up to 15 cfs (closer to 6 cfs on average) from the North Fork Cosumnes River under Pre-1914 water rights from May through October to supply non-potable uses for a small number of customers. If the District can identify a feasible alternative, it could refrain from diverting the water, leaving the water in the North Fork Cosumnes to contribute to in-stream beneficial uses.
• Potentially provide transfer water in normal/wet years for groundwater recharge through the Sacramento Groundwater Bank and during drier/driest years to meet LAR and south-of-Delta demand to increase instream flows below Folsom Reservoir.

Contributions to Water Supply Reliability
To contribute toward the co-equal goal of water supply reliability, the District will take the following actions:
• Continue investing in water supply reliability by adhering to its annually adopted 5-year capital improvement plan. Notable projects in that plan include:
o Construction of the Sly Park Intertie (currently under construction in 2025) o Replacement of wooden flumes with concrete
o Replacement of hypalon water storage reservoirs with concrete o Replacement of the Silver Lake Dam (scheduled to begin in 2027) • Expand its water treatment and transmission facilities as described in its then current Water and Recycled Water Master Plan (adopted on June 24, 2024).
• Potentially provide transfer water in normal years (groundwater recharge) and during drier/driest years (meet LAR demand) to increase instream flows below Folsom Reservoir.

The final section of this document includes a list of completed and ongoing District projects.

Caveats and Assurances

1. The signatories hereby acknowledge that the District’s existing Urban Water Management Plan forecasts an increase in future customer potable water demand. The signatories further acknowledge that (1) the District will need to ensure that it has sufficient available water supplies to meet forecasted future water demands throughout the District’s service area; and (2) ensuring sufficient available water supplies may require the District to undertake infrastructure and non-infrastructure projects that impact District water rights and supplies.

2. Without foregoing any current or future rights or remedies with respect to any project in particular, the Signatories hereby commit to work in good faith toward understanding each party’s respective interests and to seek to resolve any concerns regarding present and future water rights projects.

3. In the event of unforeseen circumstances, the District must be relieved of the commitments included herein. Unforeseen circumstances include, but are not limited to, curtailment of senior water rights, unanticipated infrastructure failures, forecasted carryover storage that falls below historical averages, changes in statute or regulation that inhibit the District’s ability to meet commitments, etc.

Project List and Future Water Supply Reliability Efforts The following projects and initiatives are key to the District meeting the commitments contained herein and its water supply reliability in 2030 and beyond:

Golden State Water Company
Arden System and Cordova System
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
Golden State Water Company (GSWC) is a subsidiary of American States Water Company, an investor- owned utility dedicated to increasing value through the expert management of utility assets and services. GSWC, then known as Southern California Water Company, was formed in 1929. In the 1960’s, GSWC purchased multiple water systems in Sacramento County to form the GSWC Cordova and the GSWC Arden systems. The two water systems are not hydraulically connected to each other. Today, the GSWC Cordova serves a portion of the City of Rancho Cordova and the unincorporated community of Gold River. In 2023, GSWC Cordova served approximately 15,424 connections. GSWC Arden serves a portion of the unincorporated community of Arden within the political jurisdiction of the County of Sacramento. In 2023, GSWC Arden served approximately 1,770 connections.

Supply Portfolio
GSWC Cordova’s water supplies have been augmented over time to adapt to changing conditions and provide a diverse and flexible water supply portfolio.
48 GSWC Cordova’s primary water supply consists of
groundwater pumped from the Sacramento Valley Groundwater Basin through GSWC-owned wells, and surface water from the American River that is treated at the Coloma Water Treatment Plant. Water assets include a pre-1914 appropriative water right, Aerojet GET (Groundwater Extraction and Treatment) water supplies from a remediation agreement, and native groundwater supplies. GSWC Cordova also maintains emergency connections with neighboring agencies that allows it access to additional sources of water in emergency conditions.

GSWC Arden derives its supply from the Sacramento Valley Groundwater Basin through GSWC-owned wells. GSWC Arden also maintains emergency connections with neighboring agencies that allow it access to additional sources of water in emergency conditions.

Surface Water Supplies49
For GSWC Cordova, GSWC possesses a pre-1914 appropriative right from the South Fork of the American River established by the Natoma Water Company in 1851. Natoma Water Company’s original pre-1914 water right established a maximum diversion rate “to fill a Canal Eight feet wide and Four feet deep with a current running ten miles per hour.” This correlates to a diversion rate of 60 cubic feet per section (cfs) and a maximum allocation of 32,000 acre-feet per year. This water right is held jointly with City of Folsom pursuant to a co-tenancy agreement. The co-tenancy agreement means that both the City of Folsom and GSWC have the right to use the water to the fullest extent possible as desired by the respective entities. The City of Folsom and GSWC have allocated the supplies under the entire 32,000 acre-foot water right. The City of Folsom unilaterally controls 22,000 acre-feet and GSWC controls the remaining 10,000 acre-feet of which 5,000 acre-feet is under contract. In November 1994, the City of Folsom and GSWC executed a contract under which the City of Folsom acquired the right to lease 5,000 acre-feet of water per year. As such, the basis of this water asset is held with GSWC pursuant to the co- tenancy agreement but the lease of the water asset to the City of Folsom is pursuant to a lease agreement. The 1851 filing is the earliest in priority of perfected appropriative rights on the South Fork of the American River and is recorded.

GSWC Cordova’s surface water supply is diverted from the Folsom South Canal and is treated at the Coloma/Pyrites Water Treatment Plant.

GSWC Arden does not rely on surface water supply.

Groundwater Supplies50
Groundwater supplies constitute a major component of the GSWC Cordova’s water supply portfolio. The groundwater supplies for GSWC Cordova are derived from the South American Subbasin of the Sacramento Valley Groundwater Basin. The aquifers in the area are recharged from rainfall, applied irrigation water, streambed recharge, and irrigation channel recharge. The American River provides substantial stream channel infiltration.

GSWC Cordova has eight active groundwater wells. These wells are located throughout GSWC Cordova’s service area and include both typical wells and those with wellhead treatment to address the Aerojet contamination issues in the service area.

Groundwater supply constitutes the entirety of the GSWC Arden’s water supply portfolio. The groundwater supplies for GSWC Arden are derived from the North American Subbasin of the Sacramento Valley Groundwater Basin. GSWC Arden has six active groundwater wells.

Aerojet GET Water Supply51
As of 2015, GSWC had nine wells in GSWC Cordova. Prior to 2015, fourteen wells had to be destroyed due to contamination, and another was transferred to Aerojet for use as a remediation well. As part of a settlement agreement, Aerojet is obligated to deliver 5,000 AF of granted water to GSWC each year.

Water Forum Agreement 2050
February 2026 Golden State Water Company PSA 220
This water is discharged by Aerojet remediation wells into the American River for extraction and treatment at the Carmichael Water District (CWD) water treatment plant. The treated water is then pumped under the American River and into the GSWC Cordova service area. This agreement with CWD allows GSWC to divert and use the Aerojet GET Water replacement supply.

Per GSWC’s 2020 Urban Water Management Plant (UWMP), it should be noted that additional groundwater wells may be taken offline in the future due to contamination. GSWC’s Settlement Agreement requires Aerojet to supply up to an additional 10,200 acre-feet of water per year.

Distribution System of Note
GSWC Cordova maintains an intertie with CWD, an intertie with Sacramento County Water Agency (SCWA), and emergency interconnections with SCWA, the City of Folsom, and two locations with California American Water. GSWC Arden maintains two emergency connections with Sacramento Suburban Water District (SSWD).

Current and Projected Demands
GSWC Cordova
Table 1 summarizes the GSWC Cordova demand over the last 10 years. The current GSWC Cordova service area is primarily characterized by low- to medium-density residential land use, with some mixed use, commercial, and light industrial land use also present, mostly along Sunrise Boulevard and Coloma Road.52 There is a corridor of parks and open space along the American River Parkway in the northern portion of the service area. Most development in the service area existed prior to 2015 and is not expected to change significantly through 2045 (2020 UWMP planning period).

Development and redevelopment in the existing GSWC Cordova service area, where expected, will consist mostly of incremental infill that does not significantly change existing land uses. Transit Oriented Development and mixed-use infill along Folsom Boulevard and the Gold Line light rail route will likely be among the most significant changes from current conditions within the existing service area.

unincorporated community of Gold River is primarily residential and near full build-out; future land use is expected to closely resemble current land use in this portion of the service area.

Projected water demands (Table 2) are from GSWC Cordova’s 2020 UWMP for the planning period of 2025 through 2045.53 GSWC may expand its service area boundary in the future to serve the proposed Westborough Development Project (Westborough Project) which is planned to be developed on land southeast of the current service area, east of Sunrise Boulevard and south of Folsom Boulevard. The Westborough Project site is located on lands that were once part of the Aerojet-Rocketdyne facilities and would consist of 1,665 acres of new residential, mixed-use development including 7,072 dwelling units, a town center and commercial area, parks, a school, water delivery facilities, and open spaces. The Westborough Project could potentially begin construction within the next five years and may reach full buildout by 2040.

GSWC Arden
Table 3 summarizes the GSWC Arden demand over the last 10 years. The current GSWC Arden service area is primarily characterized by low- to medium-density residential land use, with some commercial land use. The GSWC Arden System is considered near build-out. Most new connections are likely to be generated by redevelopment rather than new development. Preparation of a UWMP is not required for GSWC Arden; for the planning period of 2025 through 2045, projected demands are expected to be relatively constant compared to the existing demands.

Future Projected Diversions
GSWC Cordova will continue to use its pre-1914 appropriative right from the South Fork of the American River.

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 Golden State Water Company PSA 223
Drier Conditions Management
The fundamental management tenet for GSWC Cordova’s water service reliability in dry periods is to coordinate with the City of Folsom and United States Bureau of Reclamation (Reclamation) for its pre- 1914 appropriative surface water rights, Sacramento Central Groundwater Authority for groundwater management, and CWD for the treated Aerojet supply.54 Discretion over the amount of groundwater pumped allows GSWC Cordova to match its total supplies to meet annual demands which increases GSWC Cordova’s dry year resilience.

In 2015, the driest year in the last 100 years in California, the State Water Resources Control Board curtailed some pre-1914 appropriative water rights with priority dates as early as 1903. The 1851 water right was protected from curtailment because of its seniority. As such, the entirety of this water right was available to GSWC in all year types which makes it extremely resilient against drought conditions and regulatory curtailment.

In February 2024, the California Public Utilities Commission (CPUC) approved GSWC’s request to enter into the American River Terms of Ecosystem Support and Infrastructure Assistance Needs (ARTESIAN) Project Agreement. The ARTESIAN Agreement would require GSWC to forebear the use of up to 763 acre-feet of its surface water rights from the South Fork of the American River during three dry or critical years from 2025 through potentially 2036. In exchange, GSWC would receive grant funding to upgrade its interconnections with SCWA. This Agreement to intermittently encumber water will be similarly followed by eight other entities, working together through a Department of Water Resources (DWR) endeavor to reduce diversions from the Lower American River during dry years and increase instream flows necessary to support ecosystems and fish species, by encumbering a total of 30,000 AF of water each of those years.

GSWC acknowledges and supports the goals and general framework of the Sustainable Groundwater Management Act (SGMA) and intends to operate its surface water and groundwater supplies in a manner broadly consistent with SGMA objectives, to the extent applicable to the company and subject to regulatory and contractual obligations.

Driest Conditions Management
See previous section for Drier Conditions Management.

Critically Low Storage Conditions
See previous section for Drier Conditions Management.

Demand Management
From the perspective of GSWC, demand management is a critical strategy for ensuring long-term water supply reliability, regulatory compliance, and operational efficiency while staying committed to customer service and environmental stewardship. By offering programs such as conservation incentives, employing tiered rate structures, performing reoccurring leak detection efforts, and engaging in public education, GSWC can more effectively manage consumption, especially during drought or peak demand periods

Caveats and Assurances

1. The ability for any individual purveyor to implement the surface water diversions principles will depend on their respective opportunities and constraints.

2. In circumstances where excess water is made available by Reclamation by a Section 215 Contract between the purveyor and Reclamation due to flood control or "uncontrolled season" operations at Folsom Reservoir, for the purposes of groundwater recharge, that water would not be counted as diversion water within their Purveyor Specific Agreement (PSA), regardless of year type.

3. Protection of purveyor’s water entitlements. This Agreement shall not modify or diminish any vested water rights, including GSWC’s pre-1914 appropriative right on the Lower American River.

Use of surface water for the purpose of maintaining hydraulic control to prevent groundwater contaminant migration resulting from basin pumping shall remain a fully protected and recognized exercise of GSWC’s water entitlements.

4. Support aquifer storage and recovery for the purposes of groundwater recharge and surface banking within purveyors’ water entitlements.

5. Water demands in future UWMPs shall be re-visited and updated in the surface water diversions table.

6. GSWC is contractually obligated to use its 5,000 acre-feet of surface water rights as the baseline supply for the GSWC Cordova system.

Placer County Water Agency
Purveyor Specific Agreement
Updated: January 8, 2026
Purveyor Background
Placer County Water Agency (PCWA) was created in 1957 by a special act of the California Legislature known as the Placer County Water Agency Act. The boundaries of PCWA are coterminous with the boundaries of Placer County. PCWA has a five-member board of directors elected in each of the county’s supervisorial districts for four-year terms.

PCWA carries out a broad range of responsibilities including water resource planning and management, wholesale and retail supply of water, and hydroelectric energy production. PCWA has access to stored surface water appropriative rights and contract entitlements totaling roughly 500,000 acre-feet per year (AFY), with about half this amount being planned for consumptive use. PCWA also has access to a regionally managed sustainable groundwater supply.

PCWA currently delivers approximately 100,000 AFY of treated and untreated water to retail customers and approximately 30,000 AFY to neighboring water suppliers for resale, serving a total population of over 250,000 people in Placer County directly or indirectly. In addition, PCWA regularly makes surface water available through transfers to assist fishery protection goals in the lower American River while simultaneously providing water supplies to water purveyors across the state with limited access to water in dry years and periods of drought.

In the future, it is anticipated that PCWA will have a buildout water demand of approximately 253,000 AFY . PCWA is actively engaged in regional water planning, such as conservation and conjunctive use, to ensure sufficient water supply is available to meet demands.

Service Area
In accordance with its act, PCWA’s district boundary overlays the entire area of Placer County. However, PCWA formed Zone 6 as a boundary to reflect its practical service area under current planning in western Placer County (Figure 1). The Zone 6 service area is a financial and operational amalgamation of four separate systems acquired or developed over time. Each of these underlying systems is designated as a PCWA Zone; numbered 1, 2, 3 and 5.55 PCWA refers to Zone 6 as the “Western Water System.”

55 Previously, PCWA served an area called Zone 4. Zone 4, located in Martis Valley near Truckee, California, is now served by Northstar Community Services District.

Water Forum Agreement 2050
February 2026 Placer County Water Agency PSA 227
The Zone 6 service area extends from the community of Alta on the east, westward down the Interstate 80 corridor, and bounded by the Nevada Irrigation District to the north, the South Sutter Water District to the west, Sacramento County to the south, and El Dorado County to the east. The service area includes retail treated water deliveries to the communities of Alta, Monte Vista, Applegate, Colfax, Auburn, Loomis, Rocklin, and much of the surrounding unincorporated areas within Placer County. PCWA also provides wholesale treated water to the City of Lincoln and California American Water for use in their franchise area west of Roseville and south of Baseline Road, and to other relatively small community water systems throughout PCWA’s service area.

In addition to treated water service, PCWA provides untreated water through its extensive canal system to individual customers and water for treatment and resale by other retail water purveyors. Untreated water comprises more than half of PCWA’s delivery by volume.

PCWA also provides untreated water under its North Fork American River water rights into Folsom Lake for delivery to the San Juan Water District (SJWD), the City of Roseville, and Sacramento Suburban Water District (SSWD). Thus, PCWA’s place of use for its American River water rights extends outside of its district boundary (Figure 2).

Supply Portfolio
PCWA uses surface water as its primary water supply for delivery to its wholesale and retail customers.

PCWA may also use groundwater in dry hydrologic conditions to meet demands and may use recycled water – produced by the cities of Roseville and Lincoln – to meet demands in the future. Existing and planned supplies are described below and summarized in Table 1.

Surface Water
PCWA’s surface water supplies consist of water diverted from the Yuba, Bear, and North Fork American Rivers and its tributaries which includes the following:
• Water purchased from Pacific Gas and Electric Company (PG&E) from the Yuba and Bear Rivers (via the Drum-Spauling hydropower system) under the 1982 Zone 3 Contract Purchase Agreement and the 2015 Water Supply Agreement
• Direct diversions from the North and Middle Forks of the American River and water stored in its Middle Fork Project (MFP) under water rights permits 13856 and 13858; • Central Valley Project (CVP) water under CVP Repayment Contract 14-06-200-5082A-IR1- P from the American River
• Surface water from various small creeks under pre-1914 water rights A description of PCWA’s existing surface water supplies is provided below.

PG&E Contracts
PCWA has two water supply contracts with PG&E for the purchase of up to 125,400 AFY for irrigation and domestic purposes—100,400 AFY under an agreement for the “Western Water System” (formerly Zones 1, 2, and 5) and 25,000 AFY under another agreement for Zone 3. The underlying rights for the PG&E supply are PG&E’s pre-1914 appropriative rights to water in the Yuba and Bear Rivers, which were established prior to the time that PG&E developed hydroelectric facilities throughout the Yuba and Bear watersheds and are dedicated to consumptive needs in Nevada and Placer Counties. The water supply that PCWA purchases from PG&E is used to meet both untreated and treated water demands within PCWA’s service area.

PG&E Drum-Spaulding water supplies have historically been very reliable. However, during recent droughts the allocation of this supply has been reduced, and climate change projections indicate that this water supply will not be as reliable due to warming temperatures and reductions in precipitation as snowfall. Additionally, the age of the infrastructure in PG&E’s Drum Spaulding System has resulted in an increase in infrastructure failures and periods of outage for repairs that affect the reliability of this water supply.

American River Water Rights
PCWA holds appropriative water rights on the North Fork and Middle Fork of the American River and various tributaries thereof pursuant to Permits 13856 and 13858 through the California State Water Resources Control Board (State Water Board), Division of Water Rights, and owns and operates the MFP , a multi-purpose water supply and hydroelectric-generation project. Major components of the MFP include two storage reservoirs, five regulating reservoirs and diversion pools, and five powerhouses. The MFP seasonally stores and releases water to meet consumptive water demands within western Placer County and northern Sacramento County while simultaneously generating clean and renewable power for the California electric grid. Currently, PCWA’s use of American River water for consumptive purposes is diverted at two locations: (1) American River Pump Station (ARPS); and (2) Folsom Dam.

The two water rights permits provide water supplies to PCWA’s treated and irrigation water customers from the ARPS and to PCWA’s wholesale customers from Folsom Dam. PCWA may use water under its

03/10/2026 Item No.11.

Water Forum Agreement 2050
February 2026 Placer County Water Agency PSA 230
permitted water rights in western Placer County, as well as portions of northern Sacramento County, including SJWD and its wholesale family, SSWD, and Rio Linda/Elverta Community Water District service areas. PCWA’s wholesale customers with deliveries out of Folsom Dam currently include the City of Roseville, SJWD, and SSWD.

The year of priority for water right Permits 13856 and 13858 is 1958, one year after PCWA was established by the Placer County Water Agency Act. These water rights were originally part of a State Filed Application filed pursuant to California Water Code section 10500 and were released from priority pursuant to California Water Code section 10504. The release from priority operates as a limited exception to the rule of priority, precluding the eventual assignee of the original State Filed Application from asserting priority against PCWA.

The consumptive volume of water available to PCWA from its American River water rights is currently limited by agreement with the U.S. Bureau of Reclamation (Reclamation). This limitation is related to performance by Reclamation in providing an alternate supply to PCWA pursuant to their CVP contract.

The contextual relationship of these supplies is described below.

In November 2007, PCWA timely filed petition for extension of time with the State Water Board requesting an additional 36 years (until the year 2043) in which to put water allocated under these permits to full beneficial use. This petition was supported by members of the Environmental Caucus of the Water Forum. In March 2008, the State Water Board issued a Notice of Petition for Extension of Time (Petition) for Water Right Permits 13856 and 13858. PCWA’s Petition for Extension of Time is pending before the State Water Board.

Central Valley Project Contract
PCWA has a CVP water supply contract with Reclamation for delivery of up to 35,000 AFY for municipal and industrial purposes, including groundwater recharge programs that are consistent with applicable State law. The CVP Repayment Contract 14-06-200-5082A-IR1-P (dated February 28, 2020) remains in effect in perpetuity. Reclamation reserves the right to apportion the available CVP water supply among PCWA and other CVP water contractors under its Municipal and Industrial Water Shortage Policy.

PCWA’s point of diversion for CVP water under the CVP Contract is Folsom Dam, but the contract also includes potential for other points of diversion, including the Sacramento River, if agreed to by the Contracting Officer. PCWA does not currently own or control facilities that are capable of conveying CVP water from Folsom Dam to the PCWA service area. As such, the availability of the water supply is currently affected by physical limitation. PCWA is engaged in negotiations with Natomas Central Mutual Water Company and other regional entities to utilize existing facilities to divert and deliver PCWA’s CVP project water supplies from the Sacramento River.

PCWA is a partner agency on the RiverArc Project, which would diversify water supplies by shifting a portion of regional water demand from the American River and Folsom Reservoir to the Sacramento River. PCWA anticipates the future opportunity to divert all or a portion of its CVP contract water from a diversion on the Sacramento River as part of the RiverArc Project.

Contextual Relationship of American River Water Rights and CVP Contract PCWA completed construction of its MFP in 1967. This project has a current total storage capacity of 342,583 acre-feet (AF) in two major reservoirs and several smaller reservoirs. As originally planned, the
