The North Fork Flathead River is one of Montana's truly wild streams offering a pristine fishing experience amidst breathtaking natural beauty. Originating in British Columbia, it flows for 47 miles before entering Montana, where it forms the western boundary of Glacier National Park. This moderate-sized river is characterized by cold, clear waters flowing swiftly through mountainous terrain with numerous deep pools tucked among its many twists and turns. The North Fork is known for its exceptional water clarity, allowing visibility to the bottom even in pools exceeding fifteen feet deep. Unlike many Montana rivers, the North Fork remains undammed and wild, maintaining its natural flow patterns throughout the seasons. The river is designated as scenic upstream of Big Creek (no motors allowed) and as recreation downstream with a 10hp motor limit, though the river's character with rapids, twists, and gravel bars makes motorized travel rare.

Under the Montana Stream Access Law, the public may use rivers and streams for recreational purposes up to the ordinary high water marks. Although the law gives recreationists the right to use rivers and streams for water-related recreation, it does not give them the right to enter private lands bordering those streams or to cross private lands to gain access to streams without landowner permission. Montana's stream access law ensures public access to surface waters by public bridge or county road right-of-way. The width of a public bridge or public road right-of-way easement is the same as the public highway to which it is attached.
