Graham Creek

Graham Creek is a 2.9-mile-long (4.7 km)perennial stream in Sonoma County, California, tributary to Sonoma Creek. Graham Creek rises in the northern Sonoma Mountains and flows generally northeasterly down the northeastern flank of Sonoma Mountain. Historically this watercourse was called Wild Water Creek, a name used in the time of author Jack London, some of whose work was inspired by the stream.Steelhead, Oncorhynchus mykiss, have historically entered Graham Creek via Sonoma Creek for spawning. Stream surveys conducted from 1966 to 1986 indicated significant, but declining populations of anadromous fish. The spawning habitat of Graham Creek is considered medium to high value, with both winter and summer sheltering characteristics.

Land uses in the watershed are primarily open space, agriculture and low density residential uses; waste disposal within the watershed contains no municipal collection system and consists totally of septic and lagoon treatment. Most of the watershed is covered with native California oak woodland habitat populated with a variety of riparian and upland flora and fauna. Historical grazing that began in the 19th century caused certain ecological damage, some of which has been reversed by the present time.
