Interactive Map: Alameda County Watersheds

The Alameda County Flood Control and Water Conservation District has created full-featured, interactive maps of every watershed in Alameda County. Hover over each shaded area on this map to see the watershed/subwatershed name. Click a watershed/subwatershed on the map to see its information page. On the watershed page you can read more about its geology, hydrology, creeks, trails, and parks; view its map; and find information on restoration efforts and volunteer opportunities.
