Historically, the river was used by indigenous tribes for fishing, trading, and transportation. Today, the Kootenai River is an important source of hydroelectric power with several dams and reservoirs along its course, including the Libby Dam, which creates the 90-mile-long Lake Koocanusa. The river and its tributaries are also used for irrigation, supporting agriculture in the region. Recreational activities such as fishing, boating, and camping are popular along the river, particularly in the Kootenai National Wildlife Refuge. The Kootenai River is also known for its scenic beauty, with steep canyons, waterfalls, and abundant wildlife.
