Salmon River TMDL

The Salmon River Watershed is listed on the Section 303(d) List for impairment or threat of impairment to water quality associated with nutrients and temperature. The North Coast Regional Board is the lead agency for development of the Salmon River TMDLs. North Coast Regional Board staff performed fieldwork in the watershed in 2002. No evidence of impairment from elevated levels of nutrients was observed. As part of the 2004 update of the Section 303(d) List, Regional Board staff recommended to the State Water Resources Control Board that the Salmon River be delisted for nutrients. Regional Board staff completed the analysis and report documenting findings associated with temperature conditions and sources of temperature impairment in the Salmon River watershed. This was prepared as the Salmon River Temperature Total Maximum Daily Load and Implementation Plan. This TMDL and Implementation Plan document, as adopted on June 22, 2005 through Regional Water Board Resolution No. R1-2005-0058, is available below.

Salmon River Memorandum of Understanding

The Salmon River TMDL for Temperature and Implementation Plan (Resolution R1-2005-0058) requires the Regional Water Board and U.S. Forest Service, Klamath and Six Rivers National Forests, to develop a Memorandum of Understanding (MOU) that identifies the elements of U.S. Forest Service plans and commitments that will support achieving TMDL loading capacities and would be expected to lead to attaining temperature water quality standards.
