The St. Louis River watershed is one of the largest watersheds in northern Minnesota and the largest single contributing watershed to Lake Superior. Surface waters are abundant with 353 lakes and 97 streams segments. Large areas of forest and wetlands help to sustain areas of exceptional water quality. However, land use changes have degraded many lakes, rivers, and streams. 21 stream reaches have aquatic life impairments, as identified by high turbidity (1 reach), poor quality aquatic macro-invertebrate community (16 reaches), and/or poor quality fish community (12 reaches).
The goal of this project is to development a Total Maximum Daily Load (TMDL) study that addresses all of the non-mercury-related impaired reaches along the Red River of the North (RRN). The TMDL study will provide an analytical and strategic foundation for recommending restoration strategies for impaired waters. This phase of the project will also include civic engagement efforts by providing water quality framework and stakeholder activities for civic/citizen engagement and communication.
This is a joint project between the United States Geological Survey (USGS), Minnesota Pollution Control Agency (MPCA), North Dakota, and Manitoba. The project is a basin-wide, up-to-date water quality trend analysis using the "QWTrend" program for approximately 40 bi-national river sites to review nutrients, total suspended solids, total dissolved solids, sulfate and chloride from 1980 - 2015.
