The dam is at the outflow of what was the upper and lower Arrow Lakes; today the two lakes are joined forming one long reservoir extending 232 km (144 mi) north to Revelstoke Dam, and contains 8.76 km3 (7.1 MAF) of reservoir volume. The dam is operated by BC Hydro.[4]
The 853.4 m (2,800 ft) long earth fill and concrete dam was built as part of fulfilling Canada's obligations under the Columbia River Treaty, along with the Duncan Dam, both were built to prevent flooding and control the flow of water in the Columbia River for downstream hydroelectric dams. It was commissioned on October 10, 1968, six months ahead of schedule.[4]
Immediately downstream of the dam a 185 megawatt (MW) hydroelectric powerhouse, the Arrow Lakes Generating Station, began construction in 1999 and was completed in 2002.[5] The station is owned by the Columbia Power Corporation.
Lower Arrow Lake was raised 12 metres (40 feet) above the natural levels, resulting in several towns being dismantled and relocated before their sites were flooded, including Burton.[6][7]
The Arrow Lakes reservoir is described by BC Hydro as a "great waterway for boating", despite the effect that the 20 m (66 ft) difference between high and low water has on docks and ramps.[8] 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 craft.[9]
