In response to the recent detection of invasive mussel populations in central Montana, Glacier National Park is issuing an interim boating closure within all park waters, in accordance with the park’s Aquatic Invasive Species (AIS) Action Plan. The closure includes both motorized and hand propelled watercraft.
Glacier National Park offers a variety of boating experiences. The rivers and lakes in this mountainous region are very cold. All users (boaters, skiers, and swimmers) should be aware of the dangers of hypothermia at any time of the year.
Protect Glacier's Waters: Stop Aquatic Hitchhikers
A concern we must all address is the spread of harmful aquatic invasive species (AIS). These are non-native species that can harm native aquatic ecosystems as well as negatively impact visitor use and enjoyment of park waterways. AIS such as lake trout have been extremely detrimental to native bull trout populations, replacing them as the top aquatic predator in the many of the large lakes on the west side of Glacier. AIS can come in many other forms including other animals such as zebra and quagga mussels, plants such as Eurasian watermilfoil, or pathogens such as whirling disease. These species can hitch a ride on any equipment--boats, trailers, and float tubes, as well as on waders and wading boots. AIS have devastating impacts on native aquatic ecosystems.
Please thoroughly clean, drain, and dry all of your boating, wading, and fishing equipment before coming to the park. A free launch permit is required to launch all motorized/trailered boats in Glacier National Park. In order to qualify for the permit, all such boats must be inspected for AIS by NPS staff.
Hand-propelled watercraft such as rafts, kayaks, and canoes need a self-certification form. The signed form should be kept on the boaters person or in the vessel. The free launch permits are available during normal business hours at backcountry permit stations, visitor centers, and Park Headquarters.
Between Memorial Day and Labor Day, permits will be available 7:00 am to 7:00 pm at Park Headquarters, in West Glacier. Permits are also available, between 8:00 am to 4:30 pm, at the St. Mary Visitor Center, and the Two Medicine and Many Glacier Ranger Stations. Boaters headed to the North Fork should obtain permits at Park Headquarters. Boaters planning on early morning or late evening trips need to plan accordingly. During the rest of the year, please call ahead to arrange an inspection at (406) 888-7800.
Dates and times of operation for permit stations and visitor centers can be found in the Waterton-Glacier Guide summer issue.
Glacier National Park is only providing boat inspections and permits for boaters launching on park waters. Inspections and launch permits for Blackfeet tribal waters are available on U.S. Hwy 2 between East Glacier and Browning.
