Moyie Dam is a dam on the Moyie River in Boundary County, Idaho.
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. [1] 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. [2]
The dam creates a small, unnamed riverine reservoir on the Moyie, holding about 540 acre-feet (670,000 m3 ). [3]
The ruins of the 1923 version of the dam, the Old Eileen Dam 48°46′32″N116°09′19″W / 48.77550°N 116.15514°W , 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 52-foot (16 m) dam, washed out the left embankment, and left the dam shell intact. [4] [5] There were no casualties. The shell and rusting powerhouse equipment remain, posing an obstacle, and mystery, for white-water rafters. [6] [7]

The Malpasset Dam was an arch dam on the Reyran River, north of Fréjus on the French Riviera. It collapsed on 2 December 1959, killing 423 people in the resulting flood. The breach was caused by a tectonic fault in the impermeable rock base, which had been inadequately surveyed. Nearby road-building works, using explosives, may also have contributed to the disaster.

In Ada County east of Boise, it is directly downstream of Arrowrock Dam, a concrete arch dam completed in 1915. At the time of its construction in the early 1950s, Lucky Peak's primary purpose was flood control, with a secondary purpose of irrigation. The normal operating elevation of the full reservoir is 3,055 feet (931 m) above sea level, the empty reservoir's elevation is 2,824 feet (861 m).

McArthur Lake is a reservoir in Boundary County, Idaho, USA. It gives its name to the McArthur Lake Wildlife Corridor, which provides a bridge for wildlife to migrate between two mountainous areas. The reservoir and surrounding wetlands are rich in bird life, and are protected by the McArthur Lake Wildlife Management Area. There has been discussion about removing the dam that impounds the reservoir, which would improve the wetlands so they would support larger numbers of game birds, and would also improve the quality of water downstream.
