Unincorporated Area Clean Water Program
Urban runoff is the leading cause of water pollution in the creeks and the San Francisco Bay today. There are several simple changes we can make in our daily lives to improve and protect our local creeks and the San Francisco Bay. Click here to learn more about the history of the Clean Water Act.
What is a watershed?
A watershed is an area of land over which water flows. Watersheds are delineated by topography; ridges and valleys. An example is the San Lorenzo Creek watershed, seen on the attached map (PDF - 366kb)*. There are many small watersheds in the San Francisco Bay Area. The Bay Area is also considered a large watershed with all the water draining into the San Francisco Bay.
The Unincorporated Area of Alameda County has displayed signs depicting the boundaries of the San Lorenzo Creek Watershed, seen on the attached example (JPG - 110kb).
