    The entire Middle Fork Eel River Watershed was listed as temperature-impaired in 1994. The USEPA approved the "Middle Fork Eel River Total Maximum Daily Loads for Temperature and Sediment" in December 2003. For the 2008 303(d) List, the watershed was divided into an upper and lower section. The upper section includes the Wilderness HSA and the Black Butte River HSA. The lower section includes the Eden Valley HSA and the Round Valley HSA. This division was made in order to consider sediment data specific to individual HSAs.

    In 2008, the "Klamath River Hydrologic Unit, Wooley Creek Hydrologic Sub-Area" was removed from the "Klamath River Hydrologic Unit, Salmon River Hydrologic Area" in order to consider delisting the Wooley Creek Watershed for temperature as monitoring data indicated there may be different conditions in the Wooley Creek Watershed than the rest of the Salmon River Watershed. Upon review of the available data, there was insufficient information to determined if conditions in the Wooley Creek Watershed were different from the rest of the Salmon River Watershed. Additionally, temperature data in the Wooley Creek Watershed showed an exceedance of the evaluation guideline. Therefore, it was determined that the waterbody-pollutant combination should not be removed from the Section 303(d) List because applicable water quality standards for the pollutant are being exceeded.
