This $5.7 million project consists of designing and installing 11 new PIT Tag monitoring antennas into the existing spillway ogee. The antennas monitor the juvenile fish passing over the spillway. This work requires major demolition of the existing concrete spillway ogee and embedding the new antennas into the concrete and pouring concrete over the top. Project also includes designing and installing of the monitoring building, equipment and control system next to the spillway. Design is underway and work is scheduled to be completed early 2020.
