A swath 3x the width of the spillway (the one that had the sinkhole in it) has been cut by the water overflow.
It’s to the right, toward the dam.
You can see big @$$ chunks of concrete tumbling down the original spillway..
From another thread:
They have what they expect to be an imminent failure of the axillary spillway,” said Mike Smith, a spokesman for the California Department of Forestry and Fire Protection. “What they’re expecting is as much as 30 vertical feet of the top of the spillway could fail and could fail within one to two hours. We don’t know how much water that means, but we do know is that’s potentially 30 feet of depth of Lake Oroville.”
As far as I can tell, the auxillary spillway is to the right of the spillway that had the hole and is now 3x as wide. It is up near the top of the hill. So it sounds like that is expected to fail, and will do an end-around the long spillway in your previous video.
