Big River TMDL
Federal Status
The Big River Watershed is listed on the 303(d) List due to impairment and/or threat of impairment to water quality by sediment and temperature. The U.S. EPA established the Big River TMDL for Sediment on December 20, 2001. Please refer to the U.S. EPA Region 9 TMDL Webpage for more information, including a downloadable copy of the TMDL. Development of the temperature TMDL for the Big River is not yet scheduled.
State Status
Until recently, Regional Water Board staff planned to add TMDL implementation strategies for the Albion River Watersheds, along with the Big, Noyo, and Ten Mile Rivers, as an Action Plan to the Basin Plan. However, staff have determined that sediment waste discharge reduction and attainment of water quality standards may be more effectively achieved without amending the Basin Plan and by addressing all sediment impaired water bodies in the North Coast Region through the TMDL Implementation Policy for Sediment Impaired Receiving Waters. Please see the TMDL Implementation Policy for more information.
