Possible location for a large batch plant on the east side of the Main Spillway (adjacent to the erosion canyon). Multiple vertical "large tanks" with bottom footings may be batch plant "silos" used for aggregate or cement feeding via the conical bottom design. Typically, these "silos" are elevated on extensions or are mounted on a structure to feed to the "mixer".

I agree - looks like they’re setting up a concrete operation. I think that they’re setting this one up possibly for trucks, based on what looks like a platform being build just above the large tank towards the left of the image. It looks like where a loading mechanism might go.

It will be very interesting to watch how this job develops over the next few months. Looking back, despite all the serious issues that need to be attended to, they have done an enormous amount of work in the last 3 months with getting things somewhat under control.

Funny how productive even government can be when panic sets in.
