Twenty-five years ago, on December 24, 1997, the Los Vaqueros Dam was officially certified to operate by the California Department of Water, Division of Safety of Dams. This was one of several milestones Contra Costa Water District met to put Los Vaqueros Reservoir in service to improve water quality for our customers. Today, this vital asset brings tremendous value to our customers and the communities we serve. Over the coming months, we will be celebrating this anniversary by recognizing other significant milestones leading up to the original dedication held on May 2, 1998. Happy 25th Los Vaqueros Reservoir!
