I wouldn't call it a sinkhole, so much as a washout,....but that's a small beer at this point.
The point being is that the WEIGHT of the missing strata is what HOLDS the grout curtain and sub wall in place against the forces being applied on the lake side.
a shisttitic formation capped with schidty engineering.

I'm just seeing a LOT of misinformation and outright speculation being put forth as FACT posted here....kind of like what the MSM is putting out, and most of it is BS hyperbole....

Well this is a high stakes dilemma. The authorities are giving out misinformation and that fuels speculation. Wish I had more confidence in the wizards of smart.

it's a picture of a different part of that abortion, somewhat far removed, I believe. GTC So far removed that it isn't part of the actual structure. And by that, I mean where material was moved and built up. It's just a road on the ridge under the lip of the concrete apron that is the emergency spillway - which goes over the existing ridge. OK, so WHAT is pictured in the first pic I posted this AM ? It damn sure isn't that "different angle" schidt. DIFFERENT SPOT, and your call out on being lost is a good one. Look it all over again, carefully this time, you should see what we mean. GTC So now I am really scratching my head. That was not the first photo you posted this AM? I can't find another earlier. And yes - that one and the one I posted below it are the exact same spot.

Not impossible at all! The main spillway discharge enters the river channel at a 90deg. angle, easy to see how it could flow both ways with enough volume.
It will never back up to lake level, but could back up enough to affect the turbines discharge.
Yup, the increased back pressure starts STALLING the turbines, and computer controlled respond by increasing the excitation voltages,....bad electrical catastrophes ensue. In the case of debris actually being inducted, the almost incalculable forces involved can break the shafts / gear trains ......the equivalent of a powerful bomb going off. GTC So, if that is all correct, I take it simply that fluctuating backpressure is a very bad thing - and that makes sense. Still, for some reason, I had thought I remembered there being a way to let water pass through without spinning the turbines - but as I said, it was a long time ago when I saw it all close up.

It doesn't appear as though the spillway is part of the actual dam itself but is instead part of the surrounding landscape?

Snakeriver, Correct the spillways are on an adjacent ridge, separate from the dam.

And not only that, a lot of people (not necessarily pointing at anyone here) are assuming the the structure and the ridge below the waterline are essentially vertical, which, of course is far from the truth. That is not to say that a catastrophic failure is impossible, but it would be an (admittedly huge and accelerated) erosion event - not a collapse, as so many seem to fear.

Snakeriver, Correct the spillways are on an adjacent ridge, separate from the dam. And for good reason. As bad as the damage looks to the primary spill way there is no threat from it to the main dam structure. I have seen another image that shows an emergency spill way to the left of the damaged one. Over nothing but raw terrain. That seems to be a Hail Mary situation to save the main dam structure. There is a lot of stuff that can be controled at this point, but how much water ends up coming down that water shed is NOT one of them.

And yes - that one and the one I posted below it are the exact same spot. Nope,....LOOK at the photos posted WAY back,....two different washouts.

The geometry I'm seeing, and the repeated call out of "30 feet" indicates that that spill wall over the un clad "ridge" is 30 feet in height, and the sucker sure looks like it could blow out. Hope not. ALL predicated on the two OTHER routes of drainage being able to carry the high volume runoff anticipated. GTC

Honest question here....
The intakes for the turbines are two giant "tubes" running down the slope on the south side of the reservoir. They're screened on top, and, IIRC, have gates to choose at which level the water is allowed in. They can therefore take water from a much higher pressure than the water backing up at the discharge. How can that stall the turbines?
The turbines use most of that head up doing work turning the generator. The discharge is at a much lower pressure.

The spillway is part of the dam At the top, it is. Cross - what I have read is that core samples showed that bedrock begins 30' below the emergency spillway. It is expected that erosion would undercut the concrete apron to that point in short order, but then stop or be significantly slowed.

It is expected that erosion would undercut the concrete apron to that point in short order, but then stop or be significantly slowed. I should have worded it differently. Just saying that the auxiliary is connected to the dam, which some said it isn't. Sure it's not part of the concrete dam, but an earthen dam is still a dam.
