Gualala River Watershed Assessment and Monitoring
This report describes a scientific process of monitoring water quality in a California coastal watershed in three sections: Interagency Assessment, Estuary Assessment and Instream Monitoring. The Gualala River is a coastal watershed located north of the San Francisco Bay area, and is listed by the State Water Resources Control Board (SWRCB) as sediment impaired. The key beneficial uses of concern are associated with coldwater fisheries. For the Gualala River, the National Marine Fisheries Service (NMFS) in 1996 listed Coho salmon, and in 2000 listed steelhead trout, as threatened species under the federal Endangered Species Act (ESA). The river flows through 298 square miles of watershed along the coast of southwestern Mendocino County and northwestern Sonoma County, entering the Pacific Ocean near the town of Gualala. Elevations vary from sea level to just over 2,600 feet and terrain is most mountainous in the northern and eastern parts of the basin. Conifer forests of redwood and Douglas fir mixed with hardwoods dominate the coastal watersheds, while oak-woodland and grassland cover many slopes in the interior basin. Coho salmon naturally inhabited the streams flowing from coniferous forest but were likely sub-dominant to steelhead in interior basin areas.
