Touring Howard Hanson Dam
Col. Anthony O. Wright (center), points out features at the Howard Hanson Dam to Senator Murray and Rep. Reichert . For over 40 years, the Howard Hanson Dam and Green River levees in King County have provided effective flood control to the Green River valley. The Howard Hanson Dam is estimated to have prevented $4 billion in damage during the January 2009 storm and saved an estimated $40 million per day in lost economic output. This same storm, however, caused damage to the dam’s earthen right abutment which diminished the effectiveness of the dam.
