Fester has reasons to be worried. Someone is downplaying this for sure.


The 30' wall of water would be if the dam was filled to top and the 30' cap of the emergency spillway failed.

What isn't being addressed is the failure of the main spillway, a failure that is well below the top of the dam and if that failure led to the dam failing at that level...


Yup, a 10X and right on the money

again, think cavitation

That headwall and grout curtain are ONLY valid with OVERBURDEN holing em' down.
