A primary purpose of Glacier National Park is to preserve natural ecosystems for their aesthetic, educational, cultural, and scientific values. Through the management of fish and aquatic environments, the park hopes to encourage an appreciation for the preservation of native fishes in natural and mostly undisturbed aquatic habitats. Fishing is permitted when consistent with preservation or restoration of natural aquatic environments.

The following areas are closed to fishing:

  • Kintla Creek between Kintla Lake and Upper Kintla Lake
  • Upper Kintla Lake
  • Akokala Lake
  • Bowman Creek above Bowman Lake
  • Logging Creek between Logging Lake and Grace Lake
  • Cracker Lake
  • Slide Lake and the impounded pond below the lake

Seasons and Regulations

No fishing license is required to fish in Glacier National Park. No bull trout may be retained. Any caught incidentally must be handled carefully and immediately released. Fish Consumption Advisory: If you plan on keeping fish to eat, please check the fish consumption guidelines.

The standard park fishing season for all waters in the park is from the third Saturday in May through November 30, with the following exceptions:

  • Lake fishing open all year.
  • Waterton Lake season, catch and possession limits are the same as set by Canada. Check Canadian regulations before fishing these waters.
  • Lower Two Medicine Lake season, catch and possession limits are set by the Blackfeet Nation. Check Blackfeet Tribal regulations.
  • Hidden Lake outlet creek and an area extending into Hidden Lake for a radius of 300 feet (91.4 m) is closed to fishing during the cutthroat spawning season in order to protect spawning cutthroat trout, and to reduce the potential for bear-human conflicts.
  • North Fork of the Flathead River, catch and possession limits as well as methods of take are the same as those set by Montana Fish, Wildlife, and Parks. However, no state fishing license is required when fishing the North Fork from park lands. Check MFWP regulations before fishing.
  • Hidden Lake outlet creek and an area extending into Hidden Lake for a radius of 300 feet is closed to fishing during the cutthroat spawning season due to the concentrated presence of bears feeding on spawning cutthroat trout.
  • When fishing the Middle Fork of the Flathead River from park lands or bridges, a Montana fishing license is required and state regulations are applicable.
  • From May 1–June 15 an area extending 400 yards from shore between the Bowman Lake Ranger Station and the outlet of Bowman Lake is closed to fishing to protect spawning westslope cutthroat trout.

Catch and Possession Limits

All native fish caught must be released. There is no daily catch or possession limit on non-native fish species in the park.

• Flathead River Drainage native fish: Bull trout, westslope cutthroat trout, mountain whitefish, suckers, northern pikeminnow.

• St. Mary/Belly/Waterton River drainages native fish: Bull trout, lake trout, burbot (ling), westslope cutthroat trout, northern pike, lake whitefish, mountain whitefish, suckers.

• Missouri River Drainage (i.e. Two Medicine and Cutbank creek drainages) native fish: Westslope cutthroat trout in Midvale and Railroad creeks only. Exception: St. Mary Lake – No more than 5 fish may be harvested and possessed in combination with the following limits on individual species: 2 burbot (ling), 5 lake trout, 1 northern pike, 2 cutthroat trout, 2 mountain whitefish, and 5 lake whitefish (all are native species to the St. Mary River Drainage).

• Flathead River Drainage non-native species: Yellowstone cutthroat trout (Fish, Hidden, and Grace lakes only), lake trout, lake whitefish, kokanee, rainbow trout, and brook trout.

• St. Mary River/Belly/Waterton River drainages non-native species: Yellowstone cutthroat trout (in all lakes except St. Mary Lake-see above), rainbow trout, brook trout, and grayling.

• Missouri River Drainage (i.e. Two Medicine and Cutbank creek drainages) non-native species: lake trout, brook trout, Yellowstone cutthroat trout, and rainbow trout.

Fish Consumption Advisory

Stocking and Native Fish

Many people wonder why the National Park Service no longer stocks fish in park waters after this was done for many decades to enhance sport fishing. The reason is simple. The introduction of exotic game fishes was found to be detrimental to Glacier's native fishes. Competition for food and space, as well as hybridization with non-native species currently threatens native species populations in many areas of the park. Native bull trout have undergone dramatic reductions in abundance in many lakes on the west side of the park where lake trout have invaded.

The National Park Service is currently engaged in fisheries research to assess the status of native fish in the park and to develop programs to protect and enhance native fish populations. Ensuring the future survival of Glacier National Park's unique native fishes for the benefit and enjoyment of future generations is a key mandate of the National Park Service.

Fish Identification

Native fish such as bull and westslope cutthroat trout can be identified from other species in a number of ways:

  • Cutthroat trout have a characteristic red 'slash' under their lower jaw.
  • Bull trout have pink or orange spots on their sides with pale yellow spots on their backs.
  • Lake trout have a deeply forked tail and numerous white (light) markings on their body with no pink or orange spots on their sides.
  • Brook trout have black markings on their back and dorsal fins along with red or orange spots on their sides surrounded by blue halos.
Don't assume because a fish is small, it can't be a bull trout. Juvenile bull trout rear in small streams and can be confused with brook trout. If you don't know, LET IT GO.

Inquire at visitor centers or ranger stations for a Fish in Glacier brochure to help with identification.

Equipment and Bait
  • Fishing is allowed by hook and line only; use of only one rod per person is permitted.
  • The rod or line must be closely attended at all times.
  • Only artificial flies and lures are permitted in order to reduce harm/mortality to native fish. Exception: bait permitted when fishing in the Two Medicine drainage upstream of the Two Medicine bridge at the Running Eagle Falls parking lot as well as in the Many Glacier Valley upstream of the falls at the outlet of Swiftcurrent Lake.
  • Fishing with nets, seines, traps, drugs, or explosives is prohibited.
  • Do not deposit fish eggs, roe, food, or other substances in waters to attract fish.
  • Snagging fish in park waters or from park lands is prohibited.
  • The use of felt-soled wading boots are prohibited in order to prevent the introduction of Aquatic Invasive Species to park waters.
The use of all lead associated with fishing is prohibited within Glacier National Park. This includes weights, lures, jigs, line, etc. The only exception is a fisherman who is using a "down-rigger" may use cannon ball lead weights of 2 pounds or larger on the down-rigger cable.

Alternatives to lead are nontoxic materials such as brass, steel, bismuth, and tungsten, available at major sporting goods stores.

Boating Permits

If you are planning on fishing by boat, please visit our boating page for regulations and permit requirements. For information concerning boat permits, please visit our Aquatic Invasive Species page.

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 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.

Cleaning Fish

When cleaning fish in the backcountry, fish entrails must be disposed of by puncturing the air bladder and depositing the entrails into deep water at least 200 feet (61 m) from the nearest campsite or trail. Do not bury or burn entrails, as they will attract bears.

When cleaning fish, use garbage cans where available for entrail disposal.

The skin must remain attached to any fish harvested while in the park for staff identification purposes.


Consider yourself lucky to see a black or grizzly bear. But remember the wilderness is their home. Please be a well-mannered guest. Bears are usually shy; however, make no attempt to approach or startle them. They have been known to attack without warning. When hiking make some noise to alert them of your presence. Never offer food to bears and never get between a sow and cub. As bears have an excellent sense of smell, it is important to avoid the use of odorous food. Backcountry camping regulations require that food, cooking utensils, and food containers be suspended from the designated food hanging device at all times, except mealtimes. If needed, when not in a designated campground, suspend food and cooking utensils at least 10 feet above the ground and 4 feet from any tree trunk. In the absence of trees, store food and cooking gear in approved bear resistant food containers. Never leave food unattended.

Report all bear sightings to a ranger.

  • Power augers are prohibited on all lakes within Glacier National Park.
  • Shelters, bait, and all fishing equipment may not be left unattended.
  • No open fires are allowed. Self-contained stoves with fuel may be used.
  • Undesignated camping is not allowed on lakes or lakeshores.
  • Toilets should be used if available. Otherwise, human waste should not be disposed within 100 yards of any water source and all paper must be packed out.
