El Sobrante Reservoir (San Pablo Dam)

The San Pablo Reservoir is an open cut terminal water storage reservoir owned and operated by the East Bay Municipal Utility District (EBMUD). It is located in the valley of San Pablo Creek, north of Orinda, California, United States, and south of El Sobrante and Richmond, east of the Berkeley Hills between San Pablo Ridge and Sobrante Ridge.
The earthen San Pablo Dam, built in 1919, is located at the El Sobrante end of the reservoir, above Kennedy Grove. The reservoir has a total capacity of 38,600 acre-feet and a watershed of 23.37 square miles. A water tunnel runs under the hills to the west from the reservoir to a pumping plant in Kensington. The San Pablo Dam Road runs along the west side of the reservoir. EBMUD's Briones Reservoir is in the hills southeast of the San Pablo Reservoir and drains into the reservoir.
Although the dam impounds the waters of San Pablo Creek, the great bulk of its water is imported via the Mokelumne Aqueduct from Pardee Reservoir located over a hundred miles to the east in the Sierra Nevada foothills.
