This river is regulated by Libby Dam, which supplies water from 90-mile-long Lake Koocanusa. Besides offering a prime trout fishery, the river area affords viewing opportunities for eagles, osprey, deer, and mountain sheep. Three islands are located 2.5 miles down river from Libby that are used by ducks and geese during migrations. Located at Kootenai Falls are a picnic area, viewpoint, and an overpass access to a swinging bridge crossing the river. Boat ramp at Osprey Landing and Libby Riverside Park.
