The prior cut blocks to the drains in the center of the spillway look to be resealed (unless the photo angle gives this illusion).
Indeed they are. I wonder if those holes cut were for inspection purposes. Nothing like getting a visual of the situation to really assess. The Dam Cam shows that they’re drilling and placing explosives across the width of the spillway at the new level.
i wonder if the part they’re removing is going to include those sections in which additional anchors were added a couple of months ago...
