Los Vaqueros Reservoir Expansion Investigation, Contra Costa County, CA
Pursuant to section 102(2)(c) of the National Environmental Policy Act (NEPA), the Department of the Interior, Bureau of Reclamation (Reclamation) will prepare an EIS to evaluate expanding the existing Los Vaqueros Reservoir and alternatives to improve water supply reliability and water quality for Bay Area water users, particularly those receiving water from the Sacramento-San Joaquin Delta; and contribute to lower cost implementation of the CALFED Environmental Water Account (EWA). Pursuant to the California Environmental Quality Act, Contra Costa Water District will prepare an EIR on the proposed project concurrent with the EIS preparation. A joint EIS/EIR document will be prepared. Reclamation was directed in Public Law 108-7, (Omnibus Appropriations Act of 2003) to conduct a feasibility-level investigation of the potential expansion of Los Vaqueros Reservoir.
