Originally called Eagle Gorge Dam, the structure was renamed by Act of Congress on July 28, 1958 to honor the man primarily responsible for its existence. Howard A. Hanson Dam is a U.S. Army Corps of Engineers flood control dam located near the headwaters of the Green River in King County. The dam spans eagle gorge, a ravine with nearly vertical rock walls. It's primary purpose is flood control in the winter and fish enhancement in the summer. Because the dam is located in a closed watershed, public access is not permitted. Construction, including 13 miles of railroad relocation, began in February 1959. Although completion was not scheduled until April 1962, the dam went into operation on Christmas day, 1961. The dam is operated and maintained by corps personnel at Mud Mountain Dam.
