American Falls Dam, Hydroelectric power station and gravity dam in Power County, Idaho.
The dam spans 1,608 meters across the Snake River and holds back water to supply the surrounding region. The structure uses the river's flow to generate electricity while also serving as a major water storage facility for irrigation.
The dam was built in the 1920s and required relocating a large portion of the town of American Falls. This project was part of broader efforts to develop the Snake River for hydropower and irrigation.
The reservoir transformed agricultural practices in the region by storing water for irrigation across dry farmland. Today, local farmers depend on this supply to maintain their crops throughout the growing season.
Several boat ramps provide water access on the southwest side and north of the dam, making it easy to reach the reservoir. The area around the water is suitable for fishing and swimming during warmer months.
The reservoir hosts trout populations that grow remarkably large in this part of Idaho. Anglers visit the area specifically because of these fish stocks.
