Moyie Dam is a dam in Boundary County, Idaho. The current 92-foot-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 1000 feet 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.
