The Alameda County Flood Control and Water Conservation District has created full-featured, interactive maps of every watershed in Alameda County. Using our website and Google Earth you can select a watershed to find information on its creeks, culverts, and storm drain system, and explore points of interest within your selected watershed. You will need your own copy of Google Earth Pro installed on your computer or electronic device to download the following:
