It does seem there’s been criminal negligence of this dam, and likely others.
I grasp only the simplest of engineering principles, so I am speaking from ignorance here, but as bad as it may get, it still is unlikely they’ll lose the dam, right?
Actually if this next storm coming through is as big as the last two....the danger just begins.
They need it dry for a while, so they can shore this structure up. Even if they had that dry spell, there is a ton of pressure on this weakened dam. They will not be able to tell how damaged this dam is until they can see it without the water flowing over it and down the spillway. They need to see if any hole, no matter how small, has been made where water might be coming through lower down the walls now.
