This image seems to be a copy of what a person posted on imgur.com
The image was taken Feb 14, 2017 AM (you can see the shadow angle of the heavy lift helicopter in the parking lot).
So this image doesn’t reveal what they were working on in the upper main spillway last night with the concrete pumping truck.
Perhaps it may be talked about in the press update today.

Since they stopped all flights over the dam, they don’t want us to see real news.
They could have set a low altitude limit, preventing all aircraft below a certain altitude to keep the helicopters safe.no
Sorry, if I sound like an unbelieveable Deploreable.
After decades living in California, I know not to believe nor trust:
1. Anything from the Brown thugs and their fellow rat thugs in the state legislature down to the rat thugs in charge of our cities and counties.
2. Any so called news from the print mediots in California.
3. Tv reports with known close relations to #1 or #2 above.
I’ve confirmed there was NO damage & thus no emergency repair work performed late last night on the upper Main Spillway sidewall.
Re: post 999
They do still have the rapid back erosion from the massive mid failure of the Main spillway. A new chunk of the slab base has broken off & is now angled. That angle is toward the sidewall flow in the first image in post 999.
