Spillway support cradle II-A replacement
The concrete cradle that supports the principal spillway pipe

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.
