Lower Wild Rice River - Turbidity: TMDL Project

This TMDL addresses a turbidity impairment in the Wild Rice River, from the confluence with the South Branch of the Wild Rice River to the Red River of the North. The primary contributing sources of the turbidity impairment appear to be upland soil erosion and stream-bank erosion. Land use is dominated by agricultural cropping and is extensively drained for that purpose.  

The Lower Wild Rice River Turbidity TMDL is currently in draft form, and is being re-noticed for a specific portion of the TMDL study. The draft TMDL is available for public review April 20, 2009 - May 20, 2009. After public noticing of the complete TMDL Study (Sept. 15, 2008 - Oct. 15, 2008), the TMDL study was revised to include additional information regarding turbidity. This revision is the only part of the TMDL Study public comment is being requested through re-noticing. The next stage is to begin the public review process.

Other waters within the Wild Rice River watershed listed as impaired will be addressed through subsequent TMDL reports.
