Description Repair defects found during an underwater inspection of the Iowa River powerhouse dam located below the pedestrian bridge connecting the Iowa River Power Restaurant to the Peninsula Well Field area.

Justification The powerhouse dam maintains the Iowa River elevation in the tract extending from the Coralville Dam to the powerhouse dam. This pool elevation directly impacts the production of the water treatment facility collector wells #1 and #2 by providing hydrostatic pressure above the well laterals. The dam's failure would also negatively impact the pedestrian bridge and other surrounding infrastructure. The inspection work has been completed. The repair design and construction remain.
