Expansion of Los Vaqueros Reservoir improves Bay Area water supply reliability and water quality while protecting Delta fisheries and providing additional Delta ecosystem benefits.
The project will include a regional intertie (the Transfer-Bethany Pipeline), improved pump stations and pipelines and increase the reservoir’s capacity up to 275,000 acre-feet.
The project builds upon the successful first phase of expansion from 100,000 to 160,000 acre-feet funded by the Contra Costa Water District and completed in 2012.
Los Vaqueros is one of the projects being evaluated in the context of a broader Bay Area effort to work collaboratively as a region to improve water supply reliability.
