Things To Do


Nestled in the mountains of Northwestern Montana lies one of the state's best-kept secrets. Recreation is abundant with ample boating, camping and hiking opportunities. Look closely - you may see bald eagles, great blue herons, Canada geese, osprey, river otters, raccoons, moose, deer, coyotes or many of the other species that make their home here. The Kootenai River is a blue ribbon trout stream. Libby Dam was built to provide flood protection for the Kootenai and lower Columbia Rivers, as well as providing an additional source of hydroelectric power for the region. Trout and kokanee salmon are also found in abundance in Lake Koocanusa. This spill operation is part of a collaborative, on-going effort to encourage migration of endangered white sturgeon into habitat in the Kootenai River upstream from Bonners Ferry, Idaho. One of the many unique features of Libby Dam is a 75-ton granite sculpture found on the face of the Treaty Tower, the largest tower on the dam.
