The Washington State Columbia Basin Commission, created for the purpose of directing state construction of the dam, whether a low dam or high dam, acquiesced to the federal takeover after finding itself hamstrung with state law requirements for such an undertaking and its own infighting. O’Sullivan personally lobbied Arthur Powell Davis, the Commissioner of Reclamation, to support the dam. The Grand Coulee Dam is the largest producer of hydroelectric power in the United States and the third largest hydroelectric facility in the world.

That year Rufus Woods, the visionary publisher of the Wenatchee World newspaper, began advocating for a dam that would provide irrigation water to the Columbia Plateau. There are three powerhouses at Grand Coulee Dam with a total rated capacity of 6,809 megawatts, making this dam the largest hydro-electric producer in the United States. • View the award-winning movie, “The Columbia — a Fountain of Life,” at the Visitor Center.

Grand Coulee allowed the government to produce aluminum and run Hanford while not disturbing the day-to-day lives of most Americans. Roosevelt initially balked at the $450 million cost estimate for Grand Coulee (it was more than the Panama Canal, he argued, and would produce more power and potentially irrigate more than was needed at the time).

Water supplied by Grand Coulee Dam irrigates more than 600,000 acres of rich farmland in the Columbia Basin annually. The John W. Keys Pump-Generator Plant, which is located on the left bank of the river just upstream from the dam, contains 12 pumps that lift water up the hillside to a canal that flows into Banks Lake, the 27-mile-long reservoir for the Columbia Basin Project. It was formed as a result of thousands of years of erosion. At its conclusion, President Franklin D. Roosevelt authorized $60 million to get the dam project started. All are expected to be returned to service by December 2020. Kettle Falls was flooded in 1940, when the Grand Coulee Dam impounded the Columbia River to create Lake Roosevelt.
