This Gualala River Total Maximum Daily Load (TMDL) for sediment is prepared as part of a Clean Water Act program to assure that State water quality standards are achieved and beneficial uses protected. Protection of cold water fish such as coho and steelhead from human caused erosion of sediment is the primary concern of this TMDL. . .

The Gualala River Watershed Technical Support Document (TSD) for Sediment is intended to guide landowners, land managers, and resource protection agencies in the protection of water quality in the Gualala River watershed. The primary objective of the Gualala River Watershed TSD for Sediment is to identify and initially quantify sources of sediment delivery in a way that allows a relative comparison of those sources and to provide information required for non-point source implementation and planning. A secondary objective of the Gualala River Watershed TSD for Sediment is to identify sediment loading allocations that, when implemented, are expected to result in the attainment of the applicable water quality standards for sediment to protect beneficial uses. The key beneficial uses of concern are associated with cold water fisheries, particularly the coho salmon (Oncorhynchus kisutch) and steelhead trout (Oncorhynchus mykiss) fisheries. . .
