Enjoying beach activities at Contra Loma
The reservoir contains catfish, black and striped bass, bluegill, trout, and red-eared sunfish for fishing.
From Contra Loma there are trail connections to Black Diamond Mines Regional Preserve.
- The lake's swim lagoon, with lifeguards in the summer, has a sandy beach with changing rooms and a refreshment stand. Shady picnic areas on a green lawn are accessible to the disabled. Swimming is permitted throughout the year, but only in the designated swim area, and at your own risk when no lifeguards are on duty.
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.
The park is open from 5 AM to 10 PM unless otherwise posted. Fees apply to parking, fishing, and dog admittance.
Recreation - Fun seekers find a host of water-related sports including swimming and wind surfing. Anglers enjoy catching several species while picnickers find a number of reservable sites.
Climate - Climate in the San Francisco Bay area varies greatly with elevation and the amount of coastal influence. Areas with more coastal influence experience moderate temperatures year round with fog likely from June through mid-August. Plan your coastal visit in the late summer or fall to ensure the best conditions for viewing the scenery. Also, occasional clear days between winter and spring storms are incomparable. Areas further inland experience greater temperature extremes, with relatively cooler winters and hot summers. Inland areas often receive frost on winter nights. As throughout most of California most of the precipitation comes in the winter months, with April through October normally very dry.
To reach Contra Loma from Highway 4 in Antioch, exit on Lone Tree Way, go right on Golf Course Road and right on Frederickson Lane to the park.
