Corra Linn Dam, Gravity dam in Nelson region, Canada.
Corra Linn Dam is a gravity dam on the Kootenay River in British Columbia, situated between the towns of Castlegar and Nelson. It is operated by FortisBC and serves both to generate electricity and to regulate water levels in Kootenay Lake.
The dam was completed in 1932 and originally worked as a run-of-river facility with no significant water storage. In 1938, modifications were made to allow controlled management of water levels for flood prevention.
The dam takes its name from the former Corra Linn Rapids, which were named after the Falls of Clyde in Scotland. Traces of this Scottish connection still appear in local place names and historical markers along the river.
The dam can be seen from public roads, and the area around it has several spots where you can get a good view of the structure. Visiting during the drier months generally gives clearer views of the water and the surrounding landscape.
In 1939, extensive excavation work was carried out at Grohman Narrows to improve water flow during spring floods and winter low-water periods. This work permanently changed the shape of the riverbed at that point along the Kootenay River.
