Interesting - photos 1 and 2 show them shooting shotcrete below the end of the upper spillway. I wonder if it will be sufficient to reduce erosion in lower flow spills. Right now, they need to spill at roughly 40,000 to 50,000 to get the water to throw beyond the weak rock and directly into the plunge pool.
Question is, will it be strong enough to hold up to the impact of water falling on it. Falling HARD on it!
I wonder what kind of time frame they anticipate before running the spillway again. It’s obviously going to be soon, but they might delay a bit if they know that they can improve things below the upper spillway. they already know that they can flow 40-50K with minimal erosion.
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....
