Hugh Keenleyside Dam

The Hugh Keenleyside Dam is an embankment structure spanning about 869 meters across the Columbia River, combining concrete and earth fill sections to manage water flow. The facility includes navigation locks that allow boats to pass through the differing water levels on either side.

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 185-megawatt power station, added in 2002, stands as the only hydroelectric facility with a navigation lock west of Manitoba.
