Named after Captain William Clark of the Corps of Discovery, this major fork of the Columbia River is often referred to as two separate rivers. The upper 125 miles above Missoula and the 120 miles below the confluence of the Blackfoot River to the confluence of the Flathead River near Paradise, Montana.
The upper river grows from a small easily-waded stream at Warm Springs to a modest-sized river by the time it reaches the confluence of the Blackfoot River just above Missoula. The upper Clark Fork has meandering and braided channels with back channels that move from open ranch land into pine forests and cottonwood bottoms as it nears Missoula.The upper section is known for its healthy brown trout population that love to eat foam dry flies and streamers.
The lower Clark Fork is characterized by big riffles and long slow-moving runs. It is a large river best suited to fishing from a boat. The lower Clark Fork is known for its opportunities to cast to large hard fighting that rise to dense hatches of small mayflies. The lower Clark Fork offers dry-fly fishing from April through November. You can expect scenic, big, open-water stretches with long bars and wooded islands, large eddies, deep holes, cottonwood bottoms, and low elevation pine forests with occasional rock outcroppings. The size of this river can be intimidating to most, but our guides are experienced on over 150 miles of this river!
