Kerr Dam (Ktunaxa: ʔa·kniǂk̓aʔnuk ) is a concrete gravity-arch dam located at river mile 72 of the Flathead River, increasing the size of Flathead Lake near Polson, Montana. The dam was designed for hydroelectricity but also serves recreational uses. The dam is named after Frank Kerr, president of the Montana Power Company at the time of the dam's completion in 1938.
In 1930, construction began on the dam by Rocky Mountain Power. A year later in 1931, a lack of funding from the Great Depression caused construction to halt. Montana State Treasurer James Brett went to Atlanta in 1934 to ask President Franklin Roosevelt for $5,000,000 to complete the dam. Knowing that the area was in desperate need of jobs, Roosevelt gave Brett the money and he came home to a hero's welcome. In 1936, the Montana Power Company restarted the project and completed it in 1938. The dam only raised Flathead Lake by 10 feet so it is not completely responsible for the reservoir. The dam's hydro power plant consists of three units that receive water from three different penstocks 1700 feet upstream.
The dam and its related hydroelectric project are located inside the boundaries of the Flathead Indian Reservation, and operated jointly by NorthWestern Energy and the Confederated Salish and Kootenai Tribes. Today, with an installed capacity of 194 MW, it provides both power—enough for about 147,000 homes—and over $9 million in annual revenue for the tribes. NorthWest Energy acquired the power plant from PPL Montana, LLC (the successor to the Montana Power Company) in 2015. The Confederated Salish and Kootenai Tribes will acquire Kerr Dam on Sept, 5 2015 for a price of $18.3M dollars.
