Welcome to the Los Vaqueros Reservoir Expansion Project website. This project is evaluating the feasibility of expanding Los Vaqueros Reservoir in Contra Costa County, California to enhance the Delta environment and improve water supply reliability and water quality for San Francisco Bay Area water users.

The U.S. Department of the Interior, Bureau of Reclamation, Mid-Pacific Region (Reclamation) and the Contra Costa Water District (CCWD) have partnered to conduct the environmental review of the project with the participation of the California Department of Water Resources (DWR) in the studies.

Reclamation and CCWD have prepared the Final Environmental Impact Statement/Environmental Impact Report (Final EIS/EIR) in accordance with the requirements of the California Environmental Quality Act and the National Environmental Policy Act. Reclamation and CCWD have reviewed the comments received during the Draft EIS/EIR public review period held from February 20 through April 21, 2009. Those comments have been fully addressed in the Final EIS/EIR, which is now available here.
CCWD Board Approves Los Vaqueros Reservoir Expansion Project!

After review of the Final Environmental Impact Statement/Environmental Impact Report (Final EIS/EIR), the CCWD Board of Directors certified the EIR and approved the Los Vaqueros Reservoir Expansion Project on March 31, 2010.  The CCWD Board of Directors resolusion is available here.  The project includes expanding the current reservoir from 100,000 acre-feet to 160,000 acre-feet.

The project is an important component of California’s long-term plan to fix the San Francisco Bay/Sacramento-San Joaquin Delta (Bay-Delta) ecosystem, while effectively meeting the needs of millions who depend on the Delta for water. In these times of uncertainty in the Delta, an expansion of Los Vaqueros Reservoir would provide reliable water in drought periods, improve water quality, help the environment, and create jobs.

The detailed design of the expansion is moving forward with construction planned to begin in 2011.
