The character of the St. Croix and Namekagon rivers change as they flow downstream, affecting where different types of boats can travel on these rivers. Small boats with shallow drafts can motor on much of the Riverway while larger boats with deep drafts are limited by water levels to areas mostly south of Highway 8 on the St. Croix.
A properly fitting US Coast Guard approved life jacket for each person is required on your vessel. Children under 13 years old including infants are required to wear a life jacket.
