Subject: 2025 Annual Water Shortage Assessment Report
Districts: All
Recommended Action
Adopt a resolution approving the 2025 Annual Water Shortage Assessment Report and authorizing the submittal of the assessment tabular report to the California Department of Water Resources and granting authority to the Executive Manager to incorporate any requested revisions made by the Carlsbad Municipal Water District Board of Directors into the report before its submission.
Executive Summary
California Water Code Section 10632.1 requires urban water suppliers such as the Carlsbad Municipal Water District to conduct an annual water supply and demand assessment and submit this data in an annual water shortage assessment report.
The purpose of this assessment is to determine whether anticipated water supplies will adequately meet anticipated demands under both current and dry-year conditions. The assessment is intended as a tool to help with local and statewide water supply planning to address any anticipated water shortages.
The 2025 annual report, which covers the period from July 1, 2025, to June 30, 2026, (Attachment A to Exhibit 1) must be submitted to the California Department of Water Resources on or before July 1, 2025.
The CMWD’s annual assessment in the 2025 annual report indicates that the current water supplies will adequately meet the demands in fiscal year 2025-26.
To comply with the requirements established in the CMWD’s Water Shortage Contingency Plan, the 2025 annual report must be approved by the CMWD Board.
The CMWD Board approved last year’s assessment on June 11, 2024, with the adoption of Resolution No. 1738.

Explanation & Analysis
The CMWD Board approved the Water Shortage Contingency Plan when it approved the 2020 Urban Water Management Plan on June 8, 2021. The water shortage response actions in the contingency plan determine how to address identified water shortages. Suppliers such as the CMWD use their water supply and demand assessment procedures from the contingency plan, along with supporting information from their management plan, to conduct annual supply and demand assessments to predict potential shortages and submit the results in an annual report to the Department of Water Resources.
Information in the report includes:
• Anticipated demand based on historical uses
• Anticipated supplies based on current sources
• Any identified shortages
• Triggered shortage response actions
• Compliance and enforcement actions
• Communication actions consistent with the supplier’s contingency plan Estimated water demand projections are based on past and current years’ data. They include residential, commercial, industrial, institutional, agricultural, irrigation and fire protection use and expected water losses.
Because the Department of Water Resources requires these demand projections to represent a dry year, an additional 7% of water use is added to the demand calculations, in accordance with the approved management plan procedures. Demand projections also include estimates for expected water distribution system losses based on historical data.
Drought Response Level 1 actions were implemented in fiscal year 2024-25, when the region had normal precipitation. While conservation actions consistent with Drought Response Level 1 continue to be implemented, the projected total demand for FY 2025–26 without conservation efforts and under a dry-year scenario is estimated at 21,213 acre-feet,1 approximately 2,900 acre-feet more than last year’s actual demand.
The CMWD’s projected supplies include:
• 14,476 acre-feet potable water purchased from the San Diego County Water Authority • 2,500 acre-feet desalinated seawater purchased from the Water Authority • 4,237 acre-feet of recycled water total from the CMWD’s two recycled water sources, which are the Carlsbad Water Recycling Facility, and the Vallecitos Water District
The CMWD’s assessment indicates that sufficient water supplies are available to meet customer demands under the Department of Water Resources’ scenarios for dry-year conditions.
Although they are not required to meet the anticipated demands, the CMWD will continue to implement demand reduction actions for Drought Response Level 1, which would likely reduce demand further. The CMWD consistently operates at a Drought Response Level 1 even when there is not a formal drought declaration to encourage best conservation practices in
1 One acre-foot is approximately 325,900 gallons of water, enough to supply 2.5 average families of four for a year.

our region’s arid climate.
Drought Response Level 1 actions are voluntary and include actions such as not washing down hard surfaces, such as driveways, patios, sidewalks and parking lots with a hose, unless necessary for safety or sanitation.
Fiscal Analysis
The 2025 annual report has no financial impact although the projects and policies that are developed from its findings, if any, may have a financial impact. These impacts will be disclosed and brought before the CMWD Board for consideration as the projects or policies are identified or implemented.
Next Steps
With the CMWD Board’s approval, staff will submit the 2025 report to the Department of Water Resources on or before July 1, 2025.
Environmental Evaluation
The proposed action is exempt from the California Environmental Quality Act, or CEQA, under CEQA Guidelines Section 15282(v) and California Water Code Section 10652, which applies to the preparation and adoption of an annual water supply and demand assessment in compliance with California Water Code Section 10632.1.

Notes: List hydrological and regulatory conditions, infrastructure capabilities, and plausible constraints which may impact the water supplies: Our wholesale water supplier, the San Diego County Water Authority, has access to additional supplies through its Carryover Storage Program, which includes in-region surface storage of approximately 40,000 acre-feet at San Vicente Reservoir. The Water Authority’s policy is to limit use of that water to one-fifth of the total per year, if needed. The Water Authority also has access to additional supplies from the Metropolitan Water District of Southern California via its preferential right to purchase water. Under a dry-year scenario, that volume of water is assumed to be at least 300,000 acre-feet per year.
