there is still likely a couple hundred cfs leaking out....this was also the case last time they stopped it, on the left side(tower side) you can see muddy water and erosion happening as the angle of the water has changed now falling straight down
I saw part of the hillside fall in the live shot and chunks of dirt falling down..
the right side side seems to be rock..but that left side is a problem
The hill seems to be mainly that brown crumbly rock with lumps of the harder gray rock here and there. Even the gray rock took a lot of erosion.
