Libby Dam, Hydroelectric power station in Lincoln County, Montana
The Libby Dam extends 931 meters across the Kootenai River, forming Lake Koocanusa with a depth reaching 110 meters at its deepest section.
Construction of the dam commenced in 1966 under the U.S. Corps of Engineers, leading to the relocation of the entire town of Rexford.
The name Koocanusa represents the cooperation between the Kootenai Indians, Canada, and the United States in developing this water management project.
The power station generates 600 megawatts through five turbines, distributing electricity across eight states including Montana, Idaho, and California.
The selective withdrawal system allows operators to release water from different levels of Lake Koocanusa to manage downstream water temperatures.
