Welcome to the North Bay Watershed Association

The North Bay Watershed Association is a group of diverse regional and local public agencies throughout the North Bay region working to craft regional approaches to managing our common watershed.

Association members work cooperatively on water resources issues and go beyond traditional boundaries to promote good stewardship of the North Bay watersheds – watersheds that drain 850 square miles of eastern Marin County, Sonoma County, southern Napa county, and portions of Solano County.
