Our Watershed

The Atascadero / Green Valley Watershed is in western Sonoma County and is part of the larger Russian Russian River watershed.

Atascadero Creek flows north through western Sebastopol and Graton, and into Green Valley Creek, continuing on through Forestville and into the Russian River. 

Native Americans have lived here for over 12,000 years . Coast Miwok and Southern Pomo people still live in our watershed within their ancestral territories.
