Flathead River Fishing Report

Fly Fishing Near Glacier National Park

The Flathead River system is a unique fishery located around Glacier National Park and is made up of three forks which eventually drain into Flathead Lake. Here at Glacier Anglers, we fish both the Middle and North Forks. Typically, we start fishing both rivers in late June through September using dry flies. Fly fishing Glacier National Park provides a healthy population of native Westslope Cutthroat Trout that are eager to eat and fun to catch.

The Middle Fork of the Flathead originates in the Great Bear Wilderness and creates the southern border of Glacier National Park. From deep in the wilderness, it flows roughly 70 miles before it’s confluence with the North Fork of the Flathead. Many sections of the Middle Fork of the Flathead are comprised of canyons as well as class II-III whitewater. We navigate these waters using rafts with custom built fishing frames instead of the traditional drift boat.

The headwaters of the North Fork of the Flathead originate in Canada and flow south into the United States. The North Fork creates the western boundary line of Glacier National Park and provides some spectacular views inside the Park. In many areas the North Fork widens up and braids in between Glacier National Park and National Forest Service lands.
