Howard A Hanson Dam "Fish Passage Facility Project" on the Green River, King County, Washington

Fish passage facilities are essential infrastructure that help restore salmon migration routes by trapping fish below dams and transporting them upstream to access critical spawning and rearing habitats; the Tacoma Fish Passage Facility on the Green River exemplifies this approach by trapping salmon and steelhead below the 1912 diversion dam and hauling them three miles to release above Howard Hanson Dam, thereby unlocking 100 miles of prime habitat and potentially producing more salmon than any other project in the Puget Sound region.
