Fact Sheets
Gualala River TMDL Overview
The Gualala River is included on the Clean Water Act 303(d) list for impairments associated with excessive sediment and high temperatures. A TMDL addressing sediment impairments was established by the U.S. Environmental Protection Agency (USEPA) in December 2001. The Regional Water Board prepared a Technical Support Document (TSD) that addressed sources of sediment and temperature impairments, loading capacities, and load allocations necessary to restore sediment and temperature conditions supportive of beneficial uses related to the cold water fishery in the Gualala River Watershed. The TSD served as the basis for the USEPA's TMDLs.
The Gualala River Sediment TMDL was included in Resolution R1-2004-0087, Total Maximum Daily Load Implementation Policy for Sediment Impaired Receiving Waters in the North Coast Region, adopted by the North Coast Regional Water Quality Control Board in November 2004. The text of the resolution may be viewed by clicking here.
Regional Water Board staff are currently developing an action plan to address continuing water quality impairments in the Gualala River watershed. The goal of this action plan is to improve the quality of waters in the Gualala River watershed so that water quality standards are attained and beneficial uses of those waters are fully supported.- Final TMDL (PDF) (22 pp, 108K)
