Contra Costa Water District (CCWD) is proposing a surface storage project, the Los Vaqueros Reservoir Expansion Project (LVE Project). The LVE Project would enlarge the existing reservoir, an offstream reservoir located in southeastern Contra Costa County, from 160 thousand acre-feet (TAF) to 275 TAF. The LVE Project would upgrade existing conveyance facilities, construct new conveyance, and re-operate existing facilities to achieve the intended objectives. The LVE Project would divert water from the Sacramento-San Joaquin Delta at CCWD’s Rock Slough, Old River, and Middle River intakes, and at the Freeport Intake on the Sacramento River. The LVE Project would deliver water to agencies within CCWD’s service area, the Bay Area, the Delta, neighboring regions, and the south-of-Delta wildlife refuges.
