Eel River, Upper Main TMDL

The Upper Main Eel River Watershed is listed on the Section 303(d) List for impairment or threat of impairment to water quality associated with sediment and temperature.

US EPA is the lead agency for development of the technical TMDL for the Upper Main Eel River TMDLs. The Upper Main Eel River Technical TMDLs for Sediment and Temperature were established by US EPA in December 2004.
