The western part of the watershed is rural and the middle and eastern portions are urban. Most of the population in the Minnesota River Basin lives in this watershed, including the Twin Cities metropolitan area. The watershed includes Sibley and Scott counties, and portions of Le Sueur, Carver, Hennepin, Dakota, Rice, Nicollet, Renville and McLeod counties.
Water quality concerns include levels of sediment, bacteria, nutrients and chloride, and their impacts to fish and other aquatic life.

When lakes and rivers are polluted with phosphorus, sediment, and other contaminants, it can take years of effort and expense to restore water quality. But this restoration work is having an impact.
Water quality in the Lower Minnesota River Watershed has persistent problems with excess phosphorus, sediment, bacteria, and other contaminants, according to a new MPCA report.
