San Pablo Creek is an 18.7-mile-long (30.1 km) creek in Contra Costa County, California, United States, which drains the canyon or valley between the San Pablo Ridge and the Sobrante Ridge, parts of the Pacific Coast Ranges east of San Francisco Bay.
The creek runs from the southeast to the northwest, originating near Orinda and flowing into San Pablo Bay. It drains one of the largest watersheds in the East Bay, comprising some 41 square miles (110 km2). The creek has 34 named tributaries. The creek was dammed in 1919, forming the San Pablo Reservoir. Briones Reservoir, constructed in 1964, dams the Bear Creek tributary. San Pablo Reservoir essentially splits the creek in two, with about half of the creek and its related feeder creeks on either side of the artificial lake; for much of its course, it runs parallel to Wildcat Creek, which drains from Wildcat Canyon, the next valley to the west. The East Bay Municipal Utility District (EBMUD) gets less than 10% of its water from the creek.
The tributaries are as follows: Appian Creek, Baden Creek, Barn Creek, Bear Creek, Big Oak Creek, Briones Reservoir, Cascade Creek, Castro Creek, Coal Mine Creek, Clark Creek, Dutra Creek, El Toyonal Creek, Greenridge Creek, Inspiration Creek, Kennedy Creek, La Colina Creek, Lauterwasser Creek, Leastrot Creek, Lila Creek, Miner Creek, Newell Creek, Oak Creek, Oursan Creek, Overhill Creek, Rose Creek, Russel Creek, San Pablo Reservoir, Sather Creek, Schoolhouse Creek, Siesta Valley Creek, Tarry Creek, Tin House Creek, Wagner Creek, Wilkie Creek and Wire Ranch Creek.
The creek is helped by many community organizations. The city of San Pablo has organized cleanups, as has the Friends of Orinda Creeks. The San Pablo Watershed Neighbors Education and Resources Society (SPAWNERS) goes further than just garbage and weed cleanups and includes restoration efforts and watershed studies. SPAWNERS has built and maintained a creek bank restoration site and California native plant demonstration gardens at the El Sobrante Library adjacent to downtown El Sobrante since 2000. SPAWNERS also maintains a creek re-vegetation site at the El Sobrante Boys and Girls Club as well as an outdoor classroom project along Wilkie Creek (a tributary of San Pablo) behind De Anza High School. The damming of the creek has limited threatened steelhead spawning sites but has allowed it to continue to survive there. Native Ohlone shell mounds were once found along the creek, especially near San Pablo Bay.
