There's a damn big chunk of hill/mountainside between the spillway and the dam.
Quoting: Anonymous Coward 73421978 It is made up of soft tailings. It would cut away in minutes, or less, if there is failure. I've witnessed this up close. Water is extremely powerful...it takes no prisoners. They ran water down that damaged spillway for many days and it only cut a small (relative to the whole size) chunk out of that hill/mountainside. It's not just made of soft tailings. There's a lot of rock in there. I'm talking about the top of the spillways. If the MS fails or if the ES fails they will cut across to the dam and take it out. If the MS holds up then there is a chance. They are going to have to run the MS hard. I followed this at metabunk and it sounded iffy. Depending on whose old drafts from the 1960s you look at, the ES is 30,40,50, 60 feet of junk on top of bedrock. But now they say that bedrock has streaks of weathered schist that can crumble and erode. So it is just not safe to use it.
