the difference here is the Teton Dam failed from within the actual fill/ There was seepage along one abutment, saturation of the fill, and the ds face of the dam gave way.
Oroville Dam has an auxiliary spillway problem. I have read worst case scenario (which is pretty bad) thirty feet deep breach may form to bedrock. losing 30 feet of water off the top of that reservoir is going to be a lot of water downstream.
Nothing like losing the 700 feet of the main embankment.
