Project: Los Vaqueros Expansion

Description: The Los Vaqueros Reservoir Expansion project follows the new era approach to project formulation by emphasizing environmental water supply uses, as well as, municipal water supply reliability and quality. The existing Los Vaqueros Reservoir could be expanded by up to 275 thousand acre-feet to take full advantage of the existing state of the art fish screens currently in use in the Delta.  These fish screens have proven effective at protecting Delta Smelt, Longfin Smelt, and other species of concern from the effects of water pumping from the Delta. The Study has taken a two-step approach. Los Vaqueros Reserrvoir was expanded by 60 TAF in 2012, and can now store up to 160 TAF. With additional funding, local, state, and federal partners may study and implement a further raise to 275 TAF within the context of other Delta initiatives to improve Delta conveyance and better protect Delta fisheries, including long-term programs being explored in the BDCP. The larger reservoir expansion study is put on hold due to lack of State funding.
