Moyie Dam, Gravity dam in Boundary County, Idaho, United States.
The concrete structure on the Moyie River measures 92 feet in height and generates hydroelectric power through three downstream powerhouses.
The dam, constructed in 1950, replaced the Old Eileen Dam from 1923, which experienced a breach during a flood in 1925.
The facility represents one of three municipal hydropower sources in Idaho, contributing substantial revenue to Bonners Ferry's general fund.
The dam creates a reservoir capable of storing 540 acre-feet of water, supporting local water management and power generation needs.
The previous Old Eileen Dam remains stand as one of few concrete single-angle thin-arch dams that experienced a breach without structural failure.
