Quite possible, perhaps even likely, though there is a LOT less debris present this time around since the loose material has already been eroded away.
Another possibility in relation to the plant is the re-routing of the power lines. We only get to see the pictures of the linemen working on assembling the "temporary" structures, but there are also crews working in the power station at the base of the dam. It is quite possible that one or two of the original 3 lines have been taken out of service for a couple of days to allow them to re-terminate the new lines. They cannot do that work while energized. That would limit the amount of power that the plant could produce due to the lack of full line capacity.
It would make sense to coordinate that work with the operation of the spillway as much as possible.
THEY FOUND THE FAILURE CAUSE!!
As the repair bill for the crumbling spillway and the emergency response approached $200 million last week, DWR acting Director Bill Croyle — who has exhibited a troublesome tendency to downplay the incident since it started Feb. 7 — used an inappropriate analogy when asked at a press conference whether the crisis could have been prevented and who was responsible.
“This happened. Stuff happens,” he said. “So, you get a flat tire on your car, you run your car out of oil. I mean, these things happen. We’re going to get into how this happened, why this happened.”
