Des Moines River, Petersburg State Water Access S*

The Highway 4 Bridge access point in Petersburg provides boat ramp access to the Des Moines River, a large, powerful waterway suitable for experienced paddlers and motorboaters. The Des Moines River at this location is a Class 7 stream with significant flow (averaging nearly 9,000 cubic feet per second) and notable current velocity of about 6.9 feet per second. With a regional gradient of 1.9 feet per mile, paddlers should be prepared for steady current and expect moderate to strong water conditions, particularly during high water periods.

This public access site features dual concrete ramps and a floating dock, allowing simultaneous launches of multiple vessels. The site accommodates both trailer boats (typically 12-18 feet) and carry-in canoes and kayaks. Public water accesses in Minnesota are open 24 hours unless otherwise posted. Given the Des Moines River's large size and flow rate, this access point is best suited for paddlers with river experience and appropriate skill levels for current-driven conditions.
