Is swimming allowed in the reservoir?
No. Body contact is not allowed in Los Vaqueros Reservoir or in any of the streams or ponds in the watershed. The Los Vaqueros Reservoir stores drinking water for 500,000 people in central and east Contra Costa, therefore every effort is made to prevent microbial contamination of the water in order to protect public health.
