About Lake Koocanusa

Lake Koocanusa

Lake Koocanusa is 145 KM (90 M) in length and is formed north of the Libby Dam on the Kootenay River. It straddles the Canadian and U.S. border in Montana. It was named in a contest won by Alice Beers of Rexford, Montana. The name is made from the first three letters of the Kootenay River, Canada, and USA.



Family activities include camping, boating, wake surfing, water skiing, swimming, hiking, biking, fishing, hunting and off-road motor sports.



The lake is a beautiful turquoise colour with peaceful quiet and mirror-like stillness. The arid shoreline is home to sandy beaches with summer water temperatures averaging 25.5 C (78 F).



The landscape features open grasslands with Ponderosa pine forests and spectacular views of the Rocky Mountains.
