Moyie Dam

The current 92 feet (28 m) high concrete gravity dam was built in 1950, and is owned and operated by the city of Bonners Ferry, Idaho.

The city acquired its own hydroelectric facilities in 1921 and expanded several times; three powerhouses about 1,000 feet (300 m) downstream were built in 1921, 1941, and 1982, and their combined output totals just under 4 megawatts.

It's noted as one of the few concrete single-angle thin-arch dams to be breached, although it was not a structural failure.

The shell and rusting powerhouse equipment remain, posing an obstacle, and mystery, for white-water rafters.
