When you’re looking for a perfect day trip close to home, it’s hard to beat the natural beauty and peaceful setting of Los Vaqueros Reservoir and Watershed. Whether you’re in the mood to fish, hike, bike, or simply enjoy wide open space, Los Vaqueros is one of East Contra Costa’s true hidden treasures. It offers both recreation and a glimpse into the vital natural resources that help sustain our community.
A Look Into the History of Los Vaqueros Reservoir
Part of the Contra Costa Water District, Los Vaqueros Reservoir was built not only for recreation but to protect drinking water quality in the Delta and provide reliable water to more than 500,000 residents. Voters approved the project in 1988, and construction wrapped up in 1998. The dam was later raised in 2012, expanding its capacity to store over 160,000 acre-feet of water. In addition to its critical role in water supply and emergency storage, the reservoir offers flood control, environmental protection, and year-round recreation opportunities.
Start at the Interpretive Center
Before you head out on the trails or cast your fishing line, the John Muir Interpretive Center is a great place to learn more about the watershed. Open to the public on weekends, the center features exhibits about the cultural history of the area, local wildlife, and how the reservoir helps ensure clean water for surrounding communities. During the week, the center welcomes more than 30,000 students annually through educational field trips, hands-on programs, and Delta Discovery Voyages that explore local ecology aboard a research vessel.
Interactive exhibits like the Augmented Reality Sandy Box and water flow table offer a fun and educational way to learn about topography, hydrology, and the importance of preserving our watershed.
Fishing at Los Vaqueros Reservoir
With its calm waters and well-stocked fishery, Los Vaqueros Reservoir is a favorite spot for anglers year-round. The reservoir is home to trout, largemouth bass, stripers, and catfish. Whether fishing from shore or renting a boat, there’s plenty of opportunity to reel in your catch of the day.
Fishing licenses are required for anyone 16 and older, and licenses can be purchased on-site at the bait shop. Size limits apply to certain fish species to help preserve the population, so be sure to review the latest regulations before heading out.
Rental boats are available by the hour, half-day, or full day. Private watercraft are not allowed. For the best chance at snagging a boat rental, weekdays (Tuesday through Thursday) offer discounted rates and lighter crowds. Weekends tend to fill up fast, so plan ahead if boating is part of your visit.
Hiking and Biking the Trails
Los Vaqueros Reservoir offers over 60 miles of trails, providing hikers and bikers a variety of routes through scenic hills, ridgelines, and open grasslands. The reservoir’s trail system includes detailed maps, difficulty ratings, and elevation guides online to help you plan the perfect outing. From leisurely strolls to more challenging hikes, there’s a trail for every skill level.
With hot summer temperatures, visitors are strongly encouraged to bring plenty of water, wear appropriate clothing, and pack snacks or a picnic to enjoy along the way. Emergency call boxes and horse watering spots are located throughout the watershed for added safety.
Wildlife Preservation at Its Core
As California’s first major water project designed with environmental protections from the very beginning, Los Vaqueros continues to be a success story in balancing water supply needs with habitat preservation. The Contra Costa Water District has worked to protect native wildlife, plants, and ecosystems. Species like bald eagles, California tiger salamanders, mountain lions, golden eagles, and the San Joaquin kit fox thrive alongside the reservoir.
Visitors may also encounter California red-legged frogs, rattlesnakes, and countless native wildflowers, oaks, and grasses that call the watershed home. Every hike or day on the water becomes an up-close experience with nature.
