Hollow Concrete Columns - Look prefabricated & stackable - Equipment left in RCC spillway

Series of photos from DWR drone footage gives a clear view that the vertical box like concrete columns are indeed hollow. These columns look to be made from prefabricated blocks that were stacked as evidenced from the interlocking lip at the top.

Vertical view in one of the photos shows a small "catch basin" in the open drain area outside of the footings of the spillway walls.

Another puzzle & question: How are they going to get the two bulldozers and the two excavators out of the spillway? Do you think these were left there to assist in the application of the upcoming final RCC "hardened" layer?

Dozers, Mini-Excavators, Roller Compactors Gone - No Track Marks - Craned Lifted Out

KRCA helicopter flyover Oct 27 shows all of the equipment missing from the RCC spillway. Since there are no tracks from the steel crawler tracks of the dozers on the RCC, this indicates all of these pieces of equipment were "lifted" out by crane. The heaviest piece would have been the larger Cat dozer which is just under 37,000 lbs (If I've pegged the Cat model correctly).

We'll see soon what equipment will be used to place the 1ft "hardened" RCC top layer to finish the RCC spillway section.

Dozers, Mini-Excavators, Roller Compactors …. Now you see 'em…. Oct 26..
