Lower Mississippi River regional fecal coliform TMDL

Image

This TMDL addresses 39 stream and river reaches in the Lower Mississippi and Cedar River basins that are impaired due to fecal coliform levels that violate Minnesota water quality standards. The initial report, including 20 reaches, was approved by the EPA in November 2002. Additional reaches were added and a revised TMDL report was approved by the EPA on April 5, 2006. A wide range of efforts to reduce fecal coliform bacteria in the rivers and streams of the basin is underway.
