Just saw a video on the weather channel. It looks like water is getting under parts of the emergency spillway on the left side. Not good.

Isn’t that what is causing the erosion AT the spillway?

If that's the case (undermining the spillway), then it is just about imminent. A good portion of the hill will wash away.

Also that sinkhole is prolly waaaaay larger than before; water came over top of the spillway at the long horizontal part that goes to the left, that is at the very top.

At the narrow top of the long vertical spillway, go down to where the sink hole is; you can see big @$$ pieces of concrete (grey spots in the water) coming down. At about 19 minutes in, you see the erosion to the right... :
