San Pablo Reservoir

San Pablo Ridge is a small mountain range in western Contra Costa County from Pinole to Orinda between Wildcat Canyon and San Pablo Canyon. The western flank is part of the Wildcat Creek watershed and the eastern flank is part of the San Pablo Creek watershed. To the west are the Berkeley Hills, and to the east, the Sobrante Ridge. The highest point on the San Pablo Ridge is Vollmer Peak (elevation 1,905 feet/581m), formerly called "Bald Peak", located near the point where it meets the Berkeley Hills at the head of Wildcat Canyon. San Pablo Ridge is largely undeveloped, forming part of county lands and open space, with a few privately held ranches remaining.

Wildcat Canyon is a narrow linear valley just east of the Berkeley Hills in the San Francisco Bay Area, situated in Contra Costa County, California. The canyon is bounded on its east side by the San Pablo Ridge, and is drained by Wildcat Creek which runs northwest to its outlet in San Pablo Bay. Two minor lakes or ponds lie along the creek: Jewel Lake and Lake Anza. The latter was enlarged by the construction of a small dam in the mid-20th century. An active tectonic fault, the Wildcat Fault, runs the length of the canyon. Wildcat Canyon was named for the mountain lions which used to be fairly common in the area. The southern end of the canyon adjacent to the city of Berkeley was incorporated into Tilden Regional Park in the 1930s and remains a major recreation area for local residents. Another regional park, Wildcat Canyon Regional Park, is situated at the northern end of the canyon.

Jewel Lake is a former reservoir and artificial lake along Wildcat Creek, a small stream in Northern California in Tilden Regional Park.

A wooden raised walkway built in the 1970s runs over marshland to the south of the lake. The dam and abandoned flood control machinery are visible at the north end of the lake.
