Minnesota's Impaired Waters and TMDLs
TMDL Project: Redwood River — Fecal Coliform
Background
The project is sponsored by the Redwood-Cottonwood Rivers Control Area (RCRCA). RCRCA is responsible for completing 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 Redwood River and the watershed. The Redwood River watershed's 8-digit Hydrologic Unit Code is 07020006.
The following reaches were listed as impaired at the start of the project: the Redwood River from Ramsey Creek to Minnesota River, the Redwood River from below trout stream above Marshall to Three Mile Creek (both listed in 1992), the portion of the Redwood from Clear Creek to Lake Redwood, and all of Threemile Creek (both listed in 2006). 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. Current monitoring showed that four additional reaches that were assessed are impaired and will be included in the TMDL final assessment report (see table below). This TMDL plan will assess the fecal coliform concentrations and load reductions needed for the Redwood River to meet Minnesota water quality standards.
