The end of the spillway with the enormous waterfall makes me uncomfortable since erosion back from that point working backwards along fissures to undermine the spillway basin seemed to be an aspect of design contributing to the previous failure. But presumably they have accounted for all that. It would be interesting to read the post-mortem of the previous failure and the challenging new engineering decisions behind the new design.
