Watershed Explorer

    How to use the Watershed Explorer

    This watershed map has been divided into the watersheds of Marin County. Clicking on a watershed will take you to the watershed page where further information is available. We have compiled information on watershed history, present land use, biology, and watershed processes. Most of the watersheds have been grouped, but information about each of the subwatersheds are available within these pages.

    PDF Maps

    PDFMaps for each of the watersheds are available on the individual watershed pages.
