Description

About the basin

Discover the unique environment and natural resources of the Lake Superior watersheds in Wisconsin.

Basin resources

Clear, cold and deep, Lake Superior - the largest expanse of fresh water in the world - forms Wisconsin's north coast. The Wisconsin Department of Natural Resources in the Lake Superior basin provides this site about fisheries, forests, wildlife, pollution prevention, watershed protection, tributaries, environmental protection and regulation, invasive aquatic species, recreation and special programs. Cleanest of the Great Lakes, the Lake Superior ecosystem faces threats from toxic pollution, tributary erosion, contaminated sediments, habitat loss and degradation and exotic species. The governors of Wisconsin, Michigan and Minnesota signed the Binational Program to Protect and Restore the Lake Superior basin in 1991.

See the Surface Water Data Viewer to view details about the basin.
