Don’t see much of a way to repair the spillway at this time, since it has cut a huge hole to the side of it now.
They’re letting out, 100,000 cfs, but there is still 50,000 cfs coming into the lake
It looks doable IMO: National Guard, helicopters.
It will take 1000 times the effort a timely maintenance repair would have- and only last a fraction as long.
Though there may have been damage to the dam’s foundation from the main spillway’s hole.
Anyway, without a repaired main spillway the dam will definately fail come the next rains.
