The 853.4 m (2,800 ft) long earth fill and concrete dam was built as part of fulfilling Canada's role in the Columbia River Treaty, and was intended only to control the flow of water in the Columbia River for downstream dams. It was commissioned on October 10, 1968, six months ahead of schedule.
The dam was named after Hugh Llewellyn Keenleyside, the Canadian ambassador to Mexico, 1944-1947. Hugh Keenleyside served as the chairman of the British Columbia Power Commission and co-chairman at the British Columbia Hydro and Power Authority from 1962 to 1969.
The Arrow Lakes reservoir is described by BC Hydro as a "great waterway for boating". The dam is equipped with a navigation lock, which is available at no charge to boaters. However, commercial traffic and floating logs have priority over leisure crafts.
