Lower Mississippi River WMO Watershed Restoration and Protection Strategy (WRAPS) Project: TMDL Project

Rogers LakeThe Lower Mississippi River Watershed Management Organization (LMRWMO) is located in the southeastern Twin Cities metropolitan area. The watershed encompasses approximately 35,493 acres and includes 88 lakes and wetlands, four streams, and the Mississippi River. The LMRWMO Total Maximum Daily Load (TMDL) and Watershed Restoration and Protection Strategy (WRAPS) Report is a project that is addressing the water quality and pollution sources of five lakes in the watershed.

Rogers Lake is currently meeting state water quality standards and was included in this study to assess methods for protection. Thompson Lake, Lake Augusta, and Sunfish Lake are on the Minnesota Pollution Control Agency’s 303(d) list of impaired waters due to excess nutrients (phosphorus). Pickerel Lake was added to the 2014 Proposed 303(d) Impaired Waters List in 2013 due to excess nutrients, but was removed in early 2014. Excess nutrients, like phosphorus, can stimulate the growth of nuisance algal blooms in the summer which restrict recreational activities.

The goal of this project was to quantify pollutant reductions needed to meet Minnesota’s water quality standards and to develop strategies for protection and restoration of these lakes.
