The erosion on the primary spillway is looking pretty nasty. Even if / after they manage to keep the emergency spillway from collapsing, they will probably need to continue running the primary spillway at a high flow rate to get the reservoir down to safe levels to ready for future storm systems and the coming snow melt, and this will continue to eat away at the hillside (they're currently dropping lake levels by 4" (!!) an hour). That's a significant outflow. It's a good thing that the spillways are decently far away from the actual dam structure. But it sure is going to be one expensive cleanup operation in the dry season.. Fingers crossed that things stay drier and cooler for the sake of all these people
