The Los Vaqueros Watershed consists of 18,500 acres of protected watershed land surrounding the 1,900-acre Los Vaqueros Reservoir. The reservoir stores up to 160,000 acre-feet of water for Contra Costa Water District customers in Central and Eastern Contra Costa County. See our brochure Welcome to the Los Vaqueros Watershed (PDF) for details and a map of the area.
