The Nemadji River Watershed is located south of Duluth, Minnesota, draining approximately 277,400 acres (433 square miles) of land in Carlton and Pine Counties, Minnesota and Douglas County, Wisconsin. The Nemadji River begins in northern Pine County near Maheu Lake and ends in Superior, Wisconsin at Superior Bay on the western end of Lake Superior.
The river and many of its tributaries are known to run a deep muddy brown color that has been the center of a rich history of study. The color is attributed to many unique features of the land and soil, and relate to the biological health of the fish and wildlife of the river. Additionally, our understanding of the watershed and its sensitivities to land use drives the conservation practices we chose.
There is a powerful link between land use and water quality. The lessons learned from historical land use practices on the predominantly sensitive clay soils of the Nemadji River Watershed have heightened awareness of soil erosion and its effects on water quality. The Carlton SWCD works with private land owners to help improve water quality in the Nemadji.
The MPCA website has tons of detailed information on the Nemadji Watershed including monitoring results and strategies reports that explain ways we can improve water quality.
MPCA has funded many water quality data collection efforts, helping us understand what the problems are and how we can best target our work.
From education and outreach to culvert replacements and stream restorations, there are several ongoing projects in the watershed.
Volunteers are needed to help us understand how the Nemadji is changing. Contact us if you're interested in helping out!
We are always looking for volunteers! Water monitoring is a simple and easy way to help the Watershed.
