[3] The adjacent former train station and neighbourhood were named after the rapids,[4] but the locality has been frequently misspelled as Corra Lynn.

[2] For the six-year period after the 1932 opening, the dam was not permitted to raise the level of Kootenay Lake.

After devastating floods to Idaho farmlands in 1938, the International Joint Commission granted two approvals.

[8] The second approval permitted the dam to be used to raise the level of Kootenay Lake by 2 metres, thus forming a reservoir for flood control and hydro power.

Most outflow is diverted 4.5 kilometres (2.8 mi) past Corra Linn along the Kootenay Canal to the more efficient generating station opened in 1976.
