A few things I noticed in this picture... the first is that the evac platforms for the straight away leading to the hut or whatever it is have arched supports (click pic to zoom)... that is world class theme park building in that they might never be seen.
Second is we can finally see the actual depth that the pond will be at assuming it will be maintained to within 6-10” of the top of the concrete coaster supports. Note that the other straight evac concrete has been completely coated and sealed. I assume the water will come very close to that entire structure.
