Glacier Anglers's Tip of the Week

After a few warm days followed by a big rainstorm last night, the river has bumped and is high and fast! It's still fairly blue/green, but visibility isn't great and there is a fair amount of wood debris floating down.

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.
