Compare that to yesterday's photo - it appears (to me) that the section of spillway above the initial failure is stable - the deterioration is not eroding back toward the dam:

The main spillway is the chute with the hole. The auxillary/emergency spillway is to the left of it, above the road and the winding trail down the hill. That emergency spillway is right down being overtopped, the roadway is gone and the hillside eroding. That is the one they are saying will(?) fail - it is about 30 feet tall, so it will release 30’ of the water.

The press conference right now sounds like that spillway failure is not imminent.

Water went to the right, near that hill in your pic.

A width 3x that of the spillway.

As others have said the emergency spillway is the area to the left of the main concrete spillway.

It’s a waterfall right now and the resisting force of the hill holding back the lake is being eroded back toward the concrete top. Once enough resisting force has been removed the lake will have its way.
