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.


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.



Oh the aux. No - that is on the ridge next to the dam. That ridge was there before the dam was built.

So if you remove that ridge, lake level will not change?


I never said that. Just that the material under the aux is not earth fill. It's (apparently) 30' of whatever was already there over bedrock. That first 30' - nobody expects that to last long.

Lunatic fringe....we all know you're out there.
