Maybe what we need is a Department of Prevention.
Jeebus! That’s one of the last places on Earth I would ever volunteer to go.
“Gee Dave... that sure is a big cavernous hole back in there in the direction the water comes from, isn’t it... no tellin’ how far back it goes...”
Looks like they used very little rebar in the spillway.
That picture was taken last Tuesday (2/7) I believe when the problem was first discovered and they shut off the spillway for inspection. It is very much bigger now (no one really knows how big as the water release has been greatly increased to protect the emergency spillway from use and to lower the reservoir level to provide storage for the next series of storms starting tonight).
