Wells Dam, Hydroelectric power station and gravity dam on Columbia River, Washington, United States
Wells Dam stretches across the Columbia River, utilizing ten generating units to produce 840 megawatts of electricity through its hydroelectric power station.
The construction and inauguration of Wells Dam in 1963 marked a significant expansion of Washington State's hydroelectric power infrastructure on the Columbia River system.
The dam's presence transformed the regional economy from primarily agricultural activities to include substantial energy production and water-based recreational opportunities.
Lake Pateros, formed by Wells Dam, provides opportunities for boating and fishing while supporting the facility's primary function of generating renewable electrical power.
The dam incorporates specialized Kaplan turbine runners designed for efficient electricity generation in conditions of low water head and high water volume flow.
