Alcoa Wenatchee Works opened in 1952. The Wenatchee Works was the first smelter to be built In the Pacific Northwest in the post World War 2 period and the first plant of this type built with private capital in the area since before the war.
Wenatchee Works is located eleven miles south of the city of Wenatchee, Chelan County, Washington, and one and one half miles above Rock Island Dam, the first dam built on the Columbia River. The entire site covers more than 2,700 acres, excluding some 1,700 acres of orchard land donated to Washington State University In 1972. The plant itself covers 100 acres adjacent to the Columbia River.
