If that one is the same as this one,

you can see a chunk of the hill to the right eroded away... A swath 3x the width of the original concrete spillway.
Similar - but I think I was on the thread yesterday and it just had the spillway hole and through the hole it was on rock. And then these newest videos with the water gushing around that rock through the soil.
This video gives a better reference to the distance to the toe of the dam. I don’t think there is any risk of the toe washing out - that’s a pretty long ways. On other videos where it shows the broad spillway to the left of this one that is washed out - that sure is gushing. I hope that one doesn’t get undermined and fail.
What a mess. Hopefully they can keep the mess up at the dam and prevent major flooding downstream.
