from the looks of the bedrock shown, looks like we are far from disaster.[/quote]
Probably far from disaster. It looks like the main spill way has about 20 feet of decomposed granite between the manmade concrete chute and the bedrock. Unless at some point the concrete is laying on bedrock directly there is nothing to stop it from eroding all the way to the top. If the operators had to shut the spillway gates could the emergency spill way hold up? Just some questions.
