Yea, so much depends on the nature and structure of the bedrock anchoring the dam.
Water though is currently flowing into the reservoir at 130,000 CFS, the spillway is currently taking roughly 75,000 CFS out and the dam is basically full.
The dam is 700+ feet high and granted, it isn’t vertical, more like a 45 degree slope and it is water, but with erosion each CFS basically becomes a 8 lb piece of liquid sandpaper.
