Flathead River Fishing Report

Flathead River Fishing Report, Flathead River Fishing TripsGlacier National Park Fly Fishing

When you fly fish Glacier National Park, you are fly fishing on the Flathead River system, which is a unique fishery located around Glacier National Park. The Flathead River system is made up of three forks that eventually drain into Flathead Lake. When Glacier Anglers go fly fish Glacier National Park, we go fish both the Middle and North Forks of the Flathead. Typically, we start fishing both rivers in late June through September using dry flies.

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.

Fly fishing Glacier National Park provides a healthy population of native Westslope Cutthroat Trout that are eager to eat and fun to catch.

Description: About Middle Fork Flathead River

The Middle Fork of the Flathead River originates in the heart of the Great Bear Wilderness in one of the most remote and pristine areas in the lower 48. Once the river reaches Hwy 2, just west of Marias Pass, if flows westward, following the highway and making up the majority of the southern boarder of Glacier National Park until its confluence with the North Fork near Blankenship Bridge. The Middle Fork is a true Jewel, with excellent West Slope Cutthroat fishing along its entire length.
