1. What is the general layout of the watershed?

The watershed has two entrances. There is a north entrance on Walnut Boulevard near Brentwood and a south entrance off of Vasco Road near Livermore. See Directions to Los Vaqueros.

2. 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.

3. Can I bring my dog?

No. Dogs and other pets are not allowed in the Los Vaqueros Watershed. This protects the multitude of small animals, some of which are endangered, that live in this protected watershed environment. Many of these endangered animals are easily disrupted by both the presence and scent of dogs. This rule also protects public safety and water quality. 

The Round Valley Regional Preserve, which borders Los Vaqueros, is also under this rule. At Morgan Territory Regional Preserve, which is located above the Marina, dogs are allowed.

4. Are there any parking fees?

Parking fees are $6 for the general public, $5 for seniors, and $4 for those who live in the Contra Costa Water District Service Area. See more detailed information about Fees.

5. How much does it cost to fish?

There is a $6 per person daily permit fee for fishing on site at Los Vaqueros.
