Grand Coulee Dam
Grand Coulee Dam includes three major hydroelectric power generating plants (named Third, Left, and Right) and the John W. Keys III Pump-Generating Plant. The facilities provide power generation, irrigation, flood risk management, and streamflow regulation for fish migration. Additional incidental benefits include providing flows for navigation and recreation. Grand Coulee Dam is the main feature of the Columbia Basin Project.
