About This Access Site
Stephenson Island provides boat ramp access to the Menominee River in Marinette, Wisconsin. Located at the corner of 6th Street and Water Street, this public launch offers a convenient entry point for kayakers, canoeists, and motorboaters looking to explore this major waterway. The site includes parking for vehicles and trailers, making it suitable for day trips and longer excursions.

The Menominee River is a large, flowing waterway with an average discharge of 3,491 cubic feet per second and moderate velocity of 4.71 feet per second. Paddlers should be prepared for active current and moderate gradient conditions. From Stephenson Island, you can paddle upstream approximately 2.5 miles to Scott Flowage Dam or downstream toward Lake Michigan. The site is typically accessible year-round, though winter closures may occur due to ice conditions—contact local authorities to confirm access before your trip.
