Overhead photo of Albeni Falls Dam, in Oldtown, Idaho, looking upstream. The dam consists of the powerhouse and the spillway. The powerhouse has turbines and generators that convert gravity-driven river water into hydroelectricity. The spillway stores water for downstream power production and irrigation at other dams along the Pend Oreille and Columbia Rivers, and releases water for upstream flood control. The dam currently produces over 200 million kilowatt hours of electrical energy annually.
