The Beartrap Nemadji Watershed (HUC 04010301) covers an area of approximately 1,000 square miles in northeastern Minnesota and northwestern Wisconsin. The hydrology of the watershed is characterized by numerous streams, rivers, and wetlands, which drain into Lake Superior. The area experiences significant snowfall during the winter months, which contributes to the seasonal fluctuations in surface water flow. The watershed is also home to several reservoirs, which are used for hydroelectric power generation, recreation, and water supply. The reservoirs contain a variety of constituents, including sediment, nutrients, and dissolved organic matter. Interesting climatic facts and trends include increasing temperatures and precipitation levels, as well as more frequent extreme weather events, such as flooding and droughts. These changes are expected to have significant impacts on the hydrology, ecology, and economy of the Beartrap Nemadji Watershed in the coming decades.
