Klamath River TMDL

Staff of the North Coast Regional Water Quality Control Board (Regional Water Board) are in the process of developing total maximum daily loads (TMDLs) for the Klamath River in California. Pursuant to a consent decree entered into by the U.S. Environmental Protection Agency, the Klamath River TMDLs are scheduled to be approved by December 2010.
