Libby Dam and Lake Koocanusa


Nestled in the mountains of Northwestern Montana lies one of the state's best-kept secrets. 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. Recreation is abundant with ample boating, camping and hiking opportunities. The Kootenai River is a blue ribbon trout stream. The state record rainbow trout (33 lbs) was caught right below the dam. Trout and kokanee salmon are also found in abundance in Lake Koocanusa. 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. This sculpture was part of an international competition held during construction commemorating the Columbia River Treaty, which allowed for the construction of Libby Dam. Public dam tours are available during the summer months at 10, 12, 2, and 4 o?clock daily. Group tours are available year-round with advanced notice. Due to budget cuts, the Visitor Center will be closed on Wednesdays in 2004.
