Stormy weather over Lake KoocanUsa.
Lake Koocanusa was completed in 1972 as a joint project between the United States and Canada in an effort to provide flood protection and to generate hydroelectric power. The Kootenai River fluctuated wildly in the spring causing flooding in Montana, Idaho and British Columbia. Lake Koocanusa received its name in a contest to name the Libby Dam reservoir. Alice Beers, from Rexford, Montana, combined the first three letters from KOOtenai River, and the first three letters of CANada and USA.
90-mile long Lake Koocanusa reservoir is held back by 422 foot tall Libby Dam, located 16 miles upstream from the town of Libby. The dam provides flood protection and hydroelectric power. The lake offers a multitude of recreational opportunities including boating, fishing, lakeshore camping, and picnicking.
