Corra Linn Dam

The Corra Linn Dam is a gravity dam across the Kootenay River between Castlegar and Nelson in British Columbia. The structure creates a large reservoir called Kootenay Lake and is operated by FortisBC to generate electricity for the region.

The dam was completed in 1932 and initially operated as a run-of-river facility. In 1938, modifications allowed it to control water levels for flood prevention purposes.

The name comes from the former Corra Linn Rapids, which were named after Scotland's Falls of Clyde upper falls. You can still trace this Scottish connection in how locals and historical records refer to this section of the river.

The best time to visit is during drier months when water levels are more stable. The dam itself is visible from public roads, and the surrounding area offers several vantage points from which to view the structure.

In 1939, extensive excavation of Grohman Narrows was needed to increase water flow capacity during spring freshets and winter drawdown periods. This engineering effort significantly altered the river's topography.
