Why? Because it would reveal how much of the spillway was (1) unknown in its subsurface geology, (2) reveal all of the "void" areas that the Ground Penetrating Radar identified, (3) reveal the extent of "rock bolt" reinforcement, (4) reveal "another round" of spall repair and seam repairs.
Thus, these pictures (if taken and posted) could be used as a basis to question some of the positions articulated in recent press conference/statements.
Have you noticed they are drilling in front of the Emergency Spillway? Very interesting....
Yes, I noticed the core drilling going on at the front side of the emergency spillway.
Don’t know what’s up with that.
Do we know the lake level target for re-opening the gates?
It is at 860.39 as I type this (rose 1 1/2 ft. in 24 hrs).
“... DWR has zero photos of coring, drilling, etc on the upper main spillway?”

Must be because they don’t want a terrorist to think
they could sneak in there while no one was looking
and remove the rock bolts, so it is a secret???
