Description
Mud Mountain Dam, located on the White River in Washington State USA, is owned and operated by the US Army Corps of Engineers (USACE). The project includes a high-head dam operated for flood control and a small diversion barrier downstream for directing upstream migrating fish into a trap facility designed to transfer fish into transport trucks for release upstream of the dam. Migrating fish species in the White River include Chinook, Coho, and Pink salmon; steelhead and Bull Trout. The presence of Pink Salmon in the river is relatively recent, and populations have increased dramatically in the last few years. The existing trap & haul facility is antiquated and in need of replacement to handle the increasing number of fish in the river, and the complex fish sorting requirements associated with a local fish hatchery and regional fish monitoring programs. A new facility including a new barrier in the river, a short fish ladder, and a sorting facility with a research station has been designed to accommodate an unprecedented number of returning adults. This presentation will focus on the sorting facilities, designed to sort up to 60,000 fish per day by species and tag presence. The sorting facilities include two large holding ponds, two 16-meter-long Archimedes screw lifts, visual sorting flumes, automatic tag detection equipment with fish diversion to a related Chinook Salmon hatchery adjacent to the site, and a fish handling & research station with a water-to-water truck transfer station. Some features of the project are unprecedented in scale and operational arrangement, and the entire facility needed to be fit into a small limited property boundary. The design was completed in 2017 and contractor bidding is underway. The project should be in construction by the time of the conference in December.
