Subject: Packwood and Cameron Creeks Pool and Basin Reconnaissance Study Date: August 10, 2010
BACKGROUND
The Kaweah Delta Water Conservation District (KDWCD ) is working with the City of Visalia, CalWater and Tulare Irrigation District to develop a groundwater recharge program in the Visalia region. As part of this eff ort the agencies are considering using Packwood and Cameron creeks to convey water from th e Kaweah or St. Johns rivers (originating from either the Kaweah River or CVP Fr iant-Kern Canal) to one or more basins for groundwater recharge. In-channel check structures could also be used to store water in the creeks to increase recharge.
A hydraulics and capacity analysis was previously p erformed on both Packwood and Cameron creeks along their alignments near and thro ugh the City of Visalia. A HEC- RAS model was developed for each creek to determine anticipated water surface elevations at various flow rates. In conjunction w ith the HEC-RAS models, profiles of each creek were developed to show potential capacit y and freeboard issues at various flow rates.
PURPOSE AND SCOPE
KDWCD and the City of Visalia are considering the u se of these two creeks for groundwater recharge and/or conveying surface water to recharge basins located along the creek alignments. By using existing check stru ctures or constructing new ones at strategic locations along the creeks, pools could b e developed to temporarily store water and to allow it to percolate into the aquifer or to allow the water to be diverted into adjacent basins for recharge.
A pool capacity analysis was performed for several pool alternatives along each creek alignment. Potential pool locations were identifie d that maximize the pool depth and length of pool upstream of the check structure. Fo r each pool alternative, a conceptual opinion of probable construction cost was developed to weigh the cost and benefit of each pool alternative. The data used for the analy sis was based on work developed from the previous hydraulic capacity analysis. In addition, existing and new basins were considered for recharge outside of the creek channe ls, and estimates of recharge capacity were determined.

ANALYSES
The analyses utilized the profiles developed from t he previous topographic survey and HEC-RAS modeling. In addition, all estimates of re charge rates assume, for the limited purposes of this study, a continuous percolation rate of one-half foot per day and that all percolation occurs at the floor of the channel or b asin, not on the embankments. This percolation rate is only an estimate to provide a s ense of relative benefits between alternatives studied and should not be used for any other purpose until verified through actual field tests and studies. The pools, check s tructures, and recharge basins considered for this study along each creek are show n in the attached creek plan and profile drawings.
Pool Location Selection
The portions of each creek modeled in HEC-RAS were reviewed for suitability for water storage pools. Check structures were assumed to be required to create the pools. For the purposes of this study, “check structures” coul d refer to new concrete structures, existing concrete structures, temporary earthen dam s, or existing bridges or culverts with new or existing board guides. It was assumed that the check structures should be located in areas easily accessed by District or Cit y staff for operations and maintenance purposes. Other considerations for locating the ch eck structures were the available channel freeboard, high water levels determined fro m the HEC-RAS model, depth of channel upstream of the potential check structure a nd the proximity of the site to provide benefits to the City’s groundwater.
To determine estimated pool volumes, channel cross sections from the HEC-RAS model were reviewed along with pool water surface e levations. Pool water surface elevations were selected to maintain at least one-f oot of freeboard (when possible) in the channel. Channel cross-sectional areas were es timated every 1,000 feet along each pool, with most pools being approximately 6,000 to 8,000 feet long.
Seven potential pools were identified for Packwood Creek and four were identified for Cameron Creek. See the attached pool volume calcul ations for each creek. The pools identified in this study are summarized in the tables below:

Basin Location Selection
In addition to utilizing pools within the creek cha nnels, basins near the creeks were also considered for recharge. A check structure would a gain be required to back water up to be diverted into conveyance facilities leading to t he basins. Several existing basins (shown in light blue) along the Packwood Creek alig nment that may be utilized for recharge, while it appears Cameron Creek has no exi sting adjacent basins. For purposes of estimating costs, it was assumed that a new connection facility between a creek and basin would be required, even if there is an existing connection facility, due to capacity limitations or original intended use. Sev eral existing basins currently used as parks (shown in green) within the City of Visalia a re either adjacent to or near Packwood Creek. However, these were not considered for recharge in all cases because of their current use as parks.

For the purposes of this study, it was assumed new basins would only be constructed on undeveloped land of “significant” size.
Packwood Creek
There is a storm drain line that leads from the Sto nebrook Park drainage facilities to Packwood Creek. It should be fairly easy to tie in to this line and divert water from Packwood Creek into Stonebrook Park. The park woul d need to be reconfigured to allow a significant portion of the park to be flood ed in the summertime. Clearly an effort would need to be made to mitigate the loss of park land. Some mitigation could be as park improvements incorporating the regular presenc e of water as an added park feature.
The new potential Packwood Creek basin at station 2 08+00 listed above is located on a large parcel near an existing mobile home park and railroad tracks which was previously a site of an olive processing plan. The owner of t his parcel already has plans to develop this property but may be willing to conside r a sale alternative in this down development economy. He has not been contacted.
V:\Clients\Kaweah Delta WCD - 1225\12250901-SUR\_DOCUMENTS\Reports\2010-08-10 Creek Pool and Pond Memo.doc The potential to expand the existing Blain Basins u p to 100 acres has greater potential given the City of Visalia already owns this propert y. It is slated to be developed into a regional sports park, but given its prime location from a groundwater recharge standpoint, consideration should be given to using it as a recharge site, at least for interim use. It is also well located for potential use for storm water layoff for either Packwood Creek or Mill Creek.
Cameron Creek
Data from the topographic survey indicates that Cam eron Creek is shallower than Packwood Creek, often making it more difficult to form a pool of significant volume using a check structure. However, the portion of Cameron Creek considered for this study is primarily within rural agricultural areas, allowing flexibility in selecting locations for siting and sizing recharge basins. Ideally, the connectio n facility between the creek and any recharge basin would be immediately upstream of a c heck structure to maximize water depth in the basin. General areas to consider rech arge basins along Cameron Creek include immediately east of Lovers Lane to near sta tion 330+00 just downstream of the creek’s headgate. Those areas would also allow for deeper pools when backed up with a new check structure.
A new basin location was selected near a new check structure (near station 325+00) that would put the additional recharge site in good proximity to the City’s current urban boundary. No contact with the current landowner has been made.
SUMMARY
Based on the available data and information, concep tual opinions of construction costs were developed for each check structure and pool op tion considered in this study (see the attached cost breakdowns for further details). A summary of pool improvement alternatives are shown in the tables below for each creek.

“Permanent” check and pool improvements include the construction of a permanent standalone concrete check structure with provisions for board guides. “Temporary” check and pool improvements include the constructio n of an earthen dam with a corrugated metal pipe (CMP) water control structure located within the dam. This control structure would likely consist of a large d iameter CMP vertical riser half pipe with board guides, with a horizontal outlet pipe that wo uld have the capability to convey nominal creeks flows without removing the dam. An example of such a structure is shown in Figure 1 below.
Figure 1 – CMP Half Pipe Structure
In addition, it is estimated that most tie-in facil ities used for connecting a creek to an adjacent basin would likely have construction costs in the range of $100,000 to $150,000, depending on size and capacity requirements.

NEXT STEPS
Additional work to further investigate the feasibil ity of creek and/or basin recharge activities includes:
• Performing geotechnical, insitu seepage, and/or fl ow measurement tests to verify the percolation rates within the creek channels and basins considered in this study in order to refine estimates of the amount of potential recharge capacity of the creeks and basins considered in this study;
• Refine construction estimates for check structures and basin tie-ins and prioritize projects to pursue and construct.
Additional topics to be explored include the need t o meet the future conveyance demands of Tulare Irrigation District for these cre eks and to assist the City of Visalia in utilizing these creeks as storm water control facilities:
• Reviewing how these creeks can best be used to all ow Tulare Irrigation District to meet their future conveyance demands and identify n ecessary improvements.
Some of this is expected to be accomplished as part of the Tulare Irrigation District’s System Optimization Review Study currently underway;
• Reviewing how these creeks can best be integrated in the City of Visalia’s storm water master plan.
