Bluff Creek


The federal Clean Water Act requires states to prepare a list of impaired surface waters every even numbered year. This act requires states to adopt water quality standards to protect lakes, streams, and wetlands from pollution. The standards define how much of a pollutant (bacteria, nutrients, turbidity, mercury, etc.) can be in the water and still meet designated uses, such as drinking water, fishing, and swimming. A water body is designated “impaired” if it fails to meet one or more water quality standards.

The law requires that these jurisdictions establish priority rankings for waters on the lists and develop TMDLs for these waters. A Total Maximum Daily Load, or TMDL, is a calculation of the maximum amount of a pollutant that a water body can receive and still safely meet water quality standards. For more information please visit Minnesota Pollution Control Agency or Environmental Protection Agency.
