INTERNATIONAL FALLS, MN – Voyageurs National Park staff have placed hazard markers and other buoys within park boundaries. Boaters should remember that various hazards may develop at any time during the summer without warning, and these hazards may not be marked.

Lamplighters from the United States Coast Guard (USCG) are also working on placing navigational aids in the park’s four main lakes: Rainy, Kabetogama, Namakan, and Sand Point Lakes.
