Libby Dam

Libby Dam is a concrete hydroelectric facility spanning roughly one kilometer across the Kootenai River and creating a large reservoir. The water behind it reaches depths of about 110 meters at its lowest point and supplies the region with power through five turbines.

Construction began in 1966 under the U.S. Corps of Engineers as a joint project between nations to manage water and generate power. The completion resulted in the relocation of several communities, including the entire town of Rexford.

The name Koocanusa reflects cooperation between the Kootenai Indians, Canada, and the United States in this water project. Visitors can see how the reservoir shapes the local environment and the role water plays in the region's life today.

The site is free to visit and accessible year-round, though winter weather brings harsh conditions to the area. Parking and viewpoint areas are available, offering views of the water and surrounding mountains.

The facility features a system allowing water to be released from different depths of the reservoir to manage temperatures downstream. This approach helps protect fish habitats and supports the river's natural ecosystem.
