Re: 2458 - It seems that they’ve re-routed the flow down the spillway, perhaps to work on/under the right side. Sandbags upstream again, I suspect.
Yes they diverted the waterflow to do more emergency repair drilling on the right side of the spillway. See the image in post 2,444. You can see the "mud" type flow from drill work that left its traces on the lip and edges of the concrete.
What is of interest is the debris that has a look of fiber clumps. Not sure what this is - if it is just simply dirt with grass. If so, this would have to have come from the inlet to the spillway (can't imagine workers clomping around on the spillway with clod & dirt with grass - but it's possible).
