The river has a rich history, being used as a transportation route by Native Americans and later by European settlers for logging and milling. Today, it is primarily used for recreational purposes, including fishing, kayaking, and hiking along its banks. The river's hydrology includes a number of reservoirs and dams, such as the Menomonee Falls Dam and the Valley Power Plant Dam, which provide hydroelectric power as well as flood control. The river is also used for agriculture, with farms and fields lining its banks. Despite past pollution, the river has undergone extensive cleanup efforts in recent years, and is now considered safe for recreational use.
