Kerr Dam, Concrete dam in Lake County, Montana, United States

The Séliš Ksanka Ql̓ispé Dam, formerly Kerr Dam, is a concrete gravity-arch dam on the Flathead River in Montana. Its curved crest carries a walkway with a metal railing, and below it, thick concrete piers separate spillway gates that release water in wide sheets.

Construction began in 1930 but halted during the Great Depression, and federal funds helped restart it in 1936. The dam was completed in 1938 and originally named after Frank Kerr, president of the Montana Power Company.

The dam stands within the Flathead Indian Reservation, and its current name honors the three tribes of the Confederated Salish and Kootenai. The tribal council renamed it in 2015 to reflect their unity and ongoing connection to the land and water.

The dam is best viewed from the riverbanks or from a boat on the water, as access to the structure itself is limited. Visitors should check local conditions before planning a trip, since water releases can vary and affect nearby areas.

During the Cold War, U.S. intelligence uncovered a Soviet and East German plan to sabotage the dam's turbines or spillways, though it was never carried out. The plot is documented in declassified files and defector testimonies.
