I’ve found it takes brave souls like Scott Cahill (renowned Dam expert, construction expert, consultant) who is an honest civilian that will speak up. He took a great amount of heat from what he revealed.
For those who wish to hear the best description of the “rotten rock” erosion issue of the Emergency Spillway - and everything else you wanted to know - listen to this excellent podcast from yesterday.
Scott Cahill’s interview: he stated he was not sure how this dam would fare in a repeat of the overtopping. He stated that a “V” breach event is possible (in the spillway region). What he didn’t reveal is the depth of the rotten rock. This is now known to be 797ft (at least). Thus the depth of a “V” breach would be from 901ft to 797ft = top of V to lowest point of V. That is 104ft.
—— Important:
The most critical issue lurking as an “unknown” is how saturated is the penetration of water under the Emergency Spillway. The Fox10 captured images of the huge bubbles surfacing is very telling of water penetrating to a lower elevation (i.e. through/under the ES). Since the revelation of the 36ft depth of the “rotten” rock (extreme weathered & fractured) to the elevation of 797ft, this means the patchwork they are doing for the ES overflow cannot stop the subsurface penetration or weakening in another full-on overspill (901ft+).
P.S. Again, I’d like to publicly thank you for your military service (and your family member). Keep wearing the camo’s to events as this allows others to see the core of those who gave to this nation.

re post 999
first time i have seen that..what are they doing on the mian spillway way up on that hill?
is it just a staging area to dump gravel? I doubt any reporter will ask that question
I cannot find any air shots from today of the main spillway
