Valley Branch Watershed District Total Maximum Daily Load Lower St. Croix River - Major Watershed

Document
Description
Section 303(d) of the Clean Water Act requires that every two years all states publish a list of streams and lakes that do not meet water quality standards. Waters placed on the list are considered impaired. States are required to set Total Maximum Daily Loads (TMDLs) for impaired waters in order to define the maximum amount of pollutant a waterbody can receive while maintaining water quality standards and to determine the load reductions necessary to achieve water quality standards. A TMDL is divided into a wasteload allocation (WLA) for point sources (permitted sources), a load allocation (LA) for nonpoint sources (non-permitted sources) and natural background, and a margin of safety (MOS). The goal of this TMDL report is to quantify the pollutant reductions needed to meet the MPCA's water quality standards for bacteria in Kelle's Creek and nutrients in Sunfish Lake. This TMDL was established in accordance with Section 303(d) of the Clean Water Act and provides the WLAs and LAs for the impaired water resources. This report outlines the development of the TMDLs for Kelle's Creek and Sunfish Lake and describes best management practices (BMPs) that can be implemented to work towards achieving the required pollutant reductions to these resources.
