With 27,023 acres of lakes, 563 streams, and 22 species of fish, Glacier is a place where no angler should sit with a slack line. Only a scant 10 percent of park visitors fish, so those who do typically enjoy calm vistas and a few native trout. While weather and skill variables influence success, a few tips for Glacier’s waters can help.

  • Avoid a long hike to a remote lake to fish—unless you go for the sake of the journey. While many anglers find more success in waters away from roads, remoteness doesn’t mean good fishing. Waterfalls prevent fish from reaching some streams and lakes.
  • Since arrival at a high mountain lake will most likely be midday, when fishing is lackluster, stay overnight in the backcountry or at a nearby lodge. Then fish in the morning or evening, when fish feed, for best results. Overcast days also produce better fishing than sunny days.
  • During early summer runoff, when river waters cloud with sediments, fish hang out on the bottom to feed; try lures that mimic insect larvae. Alternately, fish in lakes instead.
  • When streams run clear, fly-fishing is the most productive. Try to match a prominent hatch, but traditional high-floating attractor patterns will also move fish.
  • At lakes, look for inlets and outlets to fish, but be considerate of heavily trafficked areas.
  • Trolling from a motorboat (where allowed) or canoe is the most effective way to fish for lake trout.

Fishing in Bear Country

Bears pose special considerations. Since smells attract bears that travel waterways, lessen your bear encounter chances by keeping fishy scents away from clothing. Catch-and-release fishing minimizes attracting bears.

For cleaning fish in the front country, dispose of the entrails in bear-resistant garbage cans. In the backcountry, do not bury or burn the innards, as that may attract bears. Instead, go at least 200 feet away from a campsite or trail, puncture the air bladder, and throw the entrails into deep water. Keep only what you can eat, and eat it as soon as you can.

Native Species

Glacier Park’s fishing regulations enforce protection of native species through selected area closures and limits on taking native species. The park service no longer stocks fish, as many of the introduced species took a toll on native fish through competition for food and predation. Until 1972, an estimated 45-55 million fish and eggs were planted in Glacier’s waters, introducing arctic grayling, rainbow trout, kokanee salmon, brook trout, and Yellowstone cutthroat trout. Lake trout and lake whitefish also invaded the park’s west-side water systems through stocking in Flathead Lake.

Of Glacier’s 10 sport fish and 12 nonsport fish, the bull trout is listed as a threatened species under the Endangered Species Act. In Montana, this predatory fish, which can grow to two feet long, now inhabits less than half of its original streams due to a number of factors, including habitat degradation. No fishing for bull trout is allowed; immediately release any that are caught incidentally. Look on the dorsal fin: no black, put it back.

Glacier is also one of the few remaining strongholds for westslope cutthroat trout, which now inhabit only 2.5 percent of their original range. Threatened by interbreeding with rainbow trout, genetically pure populations of cutthroat remain in 15-19 park lakes. Conscientious anglers release them after catching them.

While the law protects bull trout, anglers need to help preserve the park’s native fishery. Learn to identify native and nonnative species. Follow park guidelines for harvesting or releasing fish. In general, release native fish; keep only your limit of nonnative species.
