Grand Coulee

Grand Coulee is best known within Washington for Grand Coulee Dam, the monumental Columbia River hydroelectric project completed in 1942. The city lies beside the dam near the Grand Coulee, a dry, steep-walled channel shaped by Ice Age floods and part of eastern Washington’s Channeled Scablands. Behind the dam, Lake Roosevelt extends upstream through the Columbia River valley, while the reservoir and power station demonstrate the scale of federal water and energy development in the American West. Built during the New Deal era, the dam remains central to regional electricity generation and irrigation.
