SUBJECT
Title

Body
RECOMMENDATION
The Administration recommends the City Council approve a Memorandum of Understanding (MOU) Regarding Coordination, Cooperation, and Cost Sharing On Preconstruction Activities Related to the Temperance Flat Reservoir (TFR) Project, to be entered into with other San Joaquin Valley public water agencies to conduct technical and financial feasibility studies for the TFR Project.
EXECUTIVE SUMMARY
Friant Dam is owned and operated by the Bureau of Reclamation (Reclamation), and was constructed between 1939 and 1942 to create Millerton Lake, which has a volume of 520 thousand acre-feet (TAF). The 520 TAF storage capacity of Millerton Lake is small relative to the average historical annual inflow to Millerton Lake of approximately 1.8 million acre-feet (MAF), which requires Millerton Lake to be filled and emptied (turned over) approximately five times per year during normal precipitation and snow pack conditions. The construction of additional water supply storage capacity in the Upper San Joaquin River watershed would provide greater operational flexibility to increase water supply reliability for agricultural, and municipal and industrial (M&I) use. The form of the additional water supply storage capacity in the Upper San Joaquin River watershed would be in the form of a new dam and reservoir system designated TFR, which would be constructed at River Mile 274 of the San Joaquin River to provide 1.26 million acre-feet (MAF) of additional storage. While the construction of TFR will only result in additional water supply yield of between 100 and 200 thousand acre-f...
