San Pablo Creek is an 18.7mi 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 41sqmi. The creek has 34 named tributaries. The creek was dammed in 1919, forming the San Pablo Reservoir.
