Navigable waters begin at the Marsh and flow well over 25 miles to Lake Michigan. It is necessary to portage several dams and falls. There is, however, a dam and portage at St. Croix Falls.
Sugar River Flows gently through forested riverbanks in the rich farmlands of southern Wisconsin.
Enjoy three wildlife areas enroute. The upper river is open with clearance around log jams.
