San Pablo Creek is a creek in Contra Costa County, California which drains the canyon 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 convert|41|sqmi|km2|-1|lk=on.

[http://www.museumca.org/creeks/1080-RescSanPablo.html San Pablo Creek Watershed] , Museum of California] The creek was dammed at two locations in 1919 [http://repositories.cdlib.org/wrca/hydrology/anderson/ An assessment of stream flow and habitat quality for steelhead trout in San Pablo Creek, Contra Costa County ] Water Resources Center Archives, University of California Water Resources Center, May 1, 2004, retrieved August 1, 2007] forming the San Pablo and Briones reservoirs, the latter of which 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 the 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 10% of its water from the creek. [http://www.spawners.net/history.html A History of the Wathershed] , Spawners, retrieved August 1, 2007]

The creek is helped by many community organizations. The city of San Pablo has organized cleanups [ [http://www.ci.san-pablo.ca.us/main/calendar/event_view.asp?EID=313&ID=1&cTYPE=2] City of San Pablo News and Events] 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. [ [http://www.spawners.net/watershedplan/index.html] SPAWNERS] Spawners will begin restoration of the creek's banks at the El Sobrante Library adjcent to downtown El Sobrante in August 2007. [ [http://www.ecologycenter.org/calendar/event.php?eventID=23499] Ecology Center] The damming of the creek has limited the endangered steelhead trout's 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.

San Pablo Creek's delta, located within the city limits of Richmond, is known as San Pablo Creek Marsh and its 300 acres are filled with an abundance of wildlife including endangered species such as the California Clapper Rail, the Salt Marsh Harvest Mouse, the threatened Black Rail, the Salt Marsh Wandering Schrew and San Pablo vole. Other animals present are the shy Salt Marsh Harvest Sparrows which live in the sloughs while Salt Marsh Yellow Throats live amounst the willows that grow along the transition between fresh creekwater and salty bay water.

History

The San Pablo Canyon through which the creek flows was in the early 19th century an open grazing area shared by adjoining Mexican ranch owners. In the latter years of the 19th century, a narrow gauge railroad, the California and Nevada, ran down the canyon. The railroad was plagued by washouts in the canyon every winter, and was relegated to serving weekend picnickers traveling from the cities on San Francisco Bay. The line through the canyon was abandoned upon the acquisition of the California and Nevada by the Santa Fe Railroad.
