Spillway support cradle II-A replacement

The concrete cradle that supports the principal spillway pipe at Dam II-A near Ryan Rd. had deteriorated, exposing the reinforcing steel.

Without proper support, the outlet of the concrete pipe could drop causing it to separate at the joint and cause damage to the dam. This project involved determining the extent of deterioration and replacing the affected concrete cradle.

The photo above shows the lake was drained to relieve any pressure of water flowing through the pipe during concrete work.
