1950s Dam photos

This view of the floating caisson shows the 'A' frame strut, which was bent by ice sliding down the spillway face.
The catwalk on rafts (foreground) carried power lines to the caisson. The caisson was built to repair the spillway
bucket section of Grand Coulee Dam with Pacific Bridge Company, contractors, in charge of repairs.
