Moyie Dam
Moyie Dam is a dam on the Moyie River in Boundary County, Idaho. The current 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 downstream were built in 1921, 1941, and 1982, and their combined output totals just under 4 megawatts. As of 1984 Bonners Ferry was one of only three Idaho cities with its own municipally owned hydropower source, and the city ran it at a small profit returned to  its general fund. The dam creates a small, unnamed riverine reservoir on the Moyie, holding about . Eileen Dam. The ruins of the 1923 version of the dam, the Old Eileen Dam , stands five miles upstream. It's noted as one of the few concrete single-angle thin-arch dams to be breached, although it was not a structural failure. A sudden flood in 1925 overtopped the dam, washed out the left embankment, and left the dam shell intact. There were no casualties. The shell and rusting powerhouse equipment remain, posing an obstacle, and mystery, for white-water rafters. Moyie Dam
