Lake Del Valle Professional Review and Guide
"Long, narrow lake in a hilly woodland setting. Operated by the East Bay Regional Park District, the 5,000-acre Del Valle Regional Park offers picnicking, 150 camping sites, swimming, boating, hiking, and horseback riding. The California Department of Fish and Game stocks trout in winter, and bass fishing is excellent in the summer. Wooded hills surrounding the lake rise to the 2,000-foot elevation. Constructed as part of the State Water Project, 700-acre Del Valle Reservoir stores water for the South Bay Aqueduct."
