Note: The Contra Costa Water District, which owns the reservoir, requires that all windsurfers shower a minimum of 2 minutes prior to entering the reservoir and wear at least a short wetsuit. Showers are located outside the restrooms and next to the beach used by windsurfers. Persons using float tubes must wear waders or other wetsuit material to eliminate body contact with the water in the reservoir. People using sea kayaks that self bail must shower prior to entering the reservoir and wear at least a short wet suit. Other dry-type kayaks are permissible with the only restriction being no rollovers or other activities that cause body contact with the water. Back to top

Park Update
- Contra Loma Reservoir
- The fishing docks are closed due to a Contra Costa Water District (CCWD) water drawdown. CCWD is lowering the reservoir elevation to 198 feet and the drawdown should be completed by Tuesday, August 19. Due to the poor water supply outlook the reservoir will not be refilled until December. The lowered reservoir water levels requires that all fishing docks remain closed until further notice.
- Grazing Update
- Cattle are grazing in Los Charros area.
