Flathead River, North Fork Professional Review and Guide
"The North Fork of the Flathead originates in British Columbia and flows south for 57 miles in Montana to the confluence of the Middle Fork just outside of West Glacier. The upper 42 miles in Montana is designated “Wild and Scenic,” according to the National Wildlife and Scenic Rivers Act.
The North Fork forms the western boundary of Glacier National Park, and provides anglers easy access, excellent scenery, and an unspoiled westslope cutthroat fishery. The cold clear waters of the North Fork are not high in nutrients and do not sustain a tremendous trout population by Montana standards, however there are certainly enough migrating westslope cutthroat, and occasional rainbow trout, to make the fishing entertaining, while taking in the overall experience of this spectacular riparian corridor.
Types of Fish: Westslope Cutthroat, Rainbow and Bull Trout."
