Salmon Creek Watershed encompasses approximately 35 square miles in western Sonoma County. Salmon Creek drains directly into the Pacific Ocean at the Salmon Creek Estuary. Salmon Creek has 6 major tributaries and links the towns of Occidental, Freestone, Bodega and Salmon Creek. It was inhabited for at least 8,000 years by Native Americans, most recently Miwok Indians, along the valleys between Freestone and Bodega.
The watershed has a diverse ecology including riparian corridors, coastal grasslands, shore dunes, redwoods, oaks, an estuary and wetlands. It is home to several endangered species, among them are freshwater shrimp, tidewater gobi, northern spotted owls, red tree voles and southern red-legged frogs. Salmon Creek Watershed is one of the few viable habitats for ocean bound steelhead.
