Cottonwood River - Fecal Coliform: TMDL Project

The project is sponsored by the Redwood-Cottonwood Rivers Control Area (RCRCA). RCRCA is the responsible for the completion of the TMDL and implementation plan with the assistance of project participants, a technical committee, and stakeholder meetings.

 
The beneficial use of aquatic recreation is impaired from fecal coliform bacteria on several reaches within the Cottonwood River and the watershed. The following reaches were listed as impaired at the start of the project: the Cottonwood River from Judicial Ditch 30 to Minnesota River was listed in 1994. Five reaches, including two reaches of the Cottonwood River, Sleepy Eye Creek, Dutch Charlie Creek, and Plum Creek, were listed for fecal coliform on the 2006. The Cottonwood River watershed 8-digit Hydrologic Unit Code is 07020008. This Total Maximum Daily Load (TMDL) report will describe the magnitude of the problem and provide direction for improving water quality at the listed reaches, as well as reaches not formally assessed but believed to exhibit similar water quality conditions. Eight reaches will be assessed in the final TMDL assessment report (see table below). This TMDL plan assesses the fecal coliform concentrations and load reductions needed for the Cottonwood River to meet Minnesota water quality standards.
