Temperance Flat Projected Timeline

 Temperance Flat Map 
The Temperance Flat Reservoir (TFR) project would be a new reservoir, formed by constructing a new dam within the footprint of the existing Millerton Lake on the San Joaquin River, approximately 20 miles northeast of Fresno, California. The TFR would provide an additional 1.26 million acre-feet of water storage capacity on the San Joaquin River that would manage water supplies stored from inflow that exceeds the operational capabilities of Millerton Lake and exchanged water supplies developed through coordinated operations with statewide water systems. 


In March 2019, the applicant for the TFR project was changed from the San Joaquin Valley Water Infrastructure Authority to the Temperance Flat Reservoir Authority. Please see the related documents for additional information.
