Hugh Keenleyside Dam, Embankment dam and hydroelectric station in Castlegar, Canada.
The Hugh Keenleyside Dam is an 853.4 m long earth fill and concrete dam on the Columbia River, 12 km upstream of Castlegar, British Columbia. Its central concrete section carries four tall blue-grey frame towers, with water released through openings below them; a curved concrete wall and earthen embankment run to the left, and a separate concrete wall continues to the right. The dam is operated by BC Hydro.
The dam began operations in 1968 following the Columbia River Treaty between Canada and the United States, aimed at controlling water flow and preventing floods. A 185-megawatt power station was later added to the site, expanding regional electricity generation.
The facility bears the name of Hugh Llewellyn Keenleyside, who served as Canadian ambassador to Mexico and contributed to British Columbia's power development.
The navigation lock is accessible during daylight hours, though operating times may vary depending on the season and water levels. It is wise to check current hours before visiting to avoid disappointment.
The navigation lock at the dam is the only one west of Manitoba, and boaters may use it free of charge. Commercial traffic and floating logs, however, take priority over leisure craft.
