Glacier Anglers's Tip of the Week

The water levels are low! If you're floating, be aware that upper stretches of the river are bony and not optimal for large rafts. Fish the fast center of the river, as well as pocket water for aerated, cold zones where fish are active and feeding in the current.

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.
