About Los Vaqueros

Los Vaqueros is a nearly 20,000 acre protected watershed that offers outstanding fishing, challenging hikes and an opportunity to learn about the fascinating history of the area. CCWD's Los Vaqueros Reservoir was expanded in 2012, and can now store up to 160,000 acre-feet of high quality water for the District's customers. It's the largest reservoir in the Bay Area. 


There are two entrances to the watershed. The north end of the watershed near Brentwood, includes the updated John Muir Interpretive Center. You can hike to the top of the dam, and there are a variety of challenging trails available with rewarding views.

The south end of the watershed near Livermore is open with trails, boat rentals and shoreline fishing. The Marina has moved, and has complete fishing supplies and and electric boat rentals. No private boats are allowed on the reservoir.
