This project included installation of a downstream migrant fish collector in the forebay on the upstream side of the dam, installation of a fish handling and counting station with connection to a fish bypass pipeline.

Early scheduling and proactive involvement to obtain all required permits, waivers, and outage agreements from the owner and regulatory agencies were required to successfully deliver this project.

Project challenges included allowable in-water-work period restrictions, maintaining water quality standards, particularly during sediment removal, maintaining operations of the unit turbines, and addressing the isolation wall constraints work during potential high river flow events.
