Rivers and Waterways in Wisconsin
Wisconsin鈥檚 river systems flow through forests, plains, and glacial landscapes, draining into the Mississippi River and the Great Lakes. Western rivers flow into the Mississippi River, while eastern rivers drain into Lake Michigan and Lake Superior. The state鈥檚 waterways are influenced by glacial history, creating many lakes and wetlands. Snowmelt and rainfall feed rivers throughout the year, and numerous reservoirs and natural lakes support water supply, recreation, and ecosystems across Wisconsin.
