The dam creating this lake was completed, but partialy collapsed before the reservoir could be completely filled. For this reason the reservoir is only partially full and is why the dam is so much higher than the lake surface. This smaller lake is now surrounded by scenic woodland. Rowboats, pedal boats and electric boats are available to rent. Canoes, kayaks and small private sailboats are allowed, but no gasoline motors are permitted.
Group picnicking facilities and a bicycle trail are available.
Chabot Reservoir Open all year with facilites for boat and bank fishing, canoeing, picnicking, and hiking. It is operated by the East Bay Regional Park District under a 32-year contract that expires in 1998. Activities operated by a private concession include fishing, picnicking, boating, and hiking. A large play apparatus for children, group picnic areas, and rental boats are available. In 1974, an 80-mile system of trails was opened for hiking and horseback riding through the District's undeveloped East Bay watershed.
