Why? Can't they patch cement under water?
- Obi_Juan_Kenobi 10y agoIt's not a question of patching cement; you have to reconstruct the slope that's been worn away under the spillway. We're talking about huge amounts of Earth.
- kbutler 10y agoUnderwater, yes. Under a stream of water moving 65,000 CFS, ripping out chunks of solid cement, probably not so much.
