Wells Dam, Hydroelectric power station and gravity dam on Columbia River, Washington, United States
Wells Dam is a hydroelectric facility spanning the Columbia River in Washington, featuring ten generating units that convert flowing water into electrical power. The structure creates a large reservoir behind it that extends upstream for several miles.
The project was developed in the 1960s as part of a broader effort to expand hydroelectric capacity in the Pacific Northwest. Its completion in 1963 significantly increased electrical output for the region.
The dam's presence transformed the regional economy from primarily agricultural activities to include substantial energy production and water-based recreational opportunities.
The dam sits in a remote area, but the water behind it is used by visitors for boating and fishing. The best time to visit is during summer months when weather is mild and recreational activities are most accessible.
The dam incorporates specialized Kaplan turbine runners designed for efficient electricity generation in conditions of low water head and high water volume flow.
