As of February 22, 2010, a new federal law allows people who can legally possess firearms under applicable federal, state, and local laws, to legally possess firearms in this park. It is the responsibility of visitors to understand and comply with all applicable state, local, and federal firearms laws before entering this park. As a starting point, please visit the Minnesota Office of the Revisor of Statutes website. Federal law also prohibits firearms in certain facilities in this park; those places are marked with signs at all public entrances.
The National Park Service has revised rules affecting the use of nine Mississippi River islands and the Coldwater Unit it owns within the 72-mile Mississippi National River and Recreation Area. These federal rules do not affect activity on private property, on city, county or state park land, or on federal land managed by other agencies. The revised regulations are known as the Superintendent's Compendium (PDF, 3.6mb).
