This project will entail implementing and testing on-the-ground measures to reduce the impacts stemming from the presence of the Hood Canal Bridge. The Hood Canal Bridge is a migration barrier to juvenile salmonids, including ESA listed Puget Sound steelhead, Puget Sound Chinook, and Hood Canal summer chum. This implementation project, which includes several components including design, fabrication, deployment, and operations will primarily help fund the operations and adaptive management of fish guidance structures and targeted acoustic predator deterrence technology on the Hood Canal Bridge. These systems will be deployed to facilitate fish passage and alter fish / predator behavior in the project area (The project area was identified as a high predation zone during phase 1 of the Hood Canal Bridge Ecosystem Assessment). In addition to assisting in the deployment and development of the systems, the Tribe will use visual acoustics (multibeam imaging sonar), and remote underwater video to ensure that they are functioning as designed. The data generated by PGST will be used to adaptively manage the systems and to provide detailed information on predator behavior, and fish-predator interactions in the project area.
