Black and white photo of Howard A. Hanson Dam, a U.S. Army Corps of Engineers dam located near the headwaters of the Green River in King County, Washington. The dam's primary purpose is flood risk reduction in the winter and fish enhancement in the summer. Construction, including 13 miles of railroad relocation, began in February 1959. The dam became operational on Christmas Day, 1961, ahead of its scheduled April 1962 completion in April 1962. Since its 1962 construction, the dam has protected hundreds of thousands of people from catastrophic flooding, and more than $23 billion in property and farmland damages have been avoided.
