About Lake Koocanusa

Lake Koocanusa is a reservoir in British Columbia (Canada) and Montana (United States) formed by the damming of the Kootenay River by the Libby Dam in 1972. The Dam was formally dedicated by President Gerald Ford on August 24, 1975.

The lake is formed north of the dam, reaching 48 miles (77 km) to the Canada–United States border and 42 miles (68 km) further into British Columbia. The lake holds 13% of the water in the Columbia River system. The town of Rexford was moved, as well as the Great Northern Railroad line. The town of Waldo, BC is now covered by the lake. What was once a barrier to river travel, Jennings Canyon is now inundated by the lake. Some points of interests to stop and enjoy along the way:

  • Libby Dam Visitor Center - offers an exhibit area, book/gift sales area and auditorium featuring "The Power and Beauty of the Kootenai, the Story of Libby Dam".
