Jim, thanks for reminding me of Ken's posted Tunnel Gulch photo, that is great help.

As to Riverside,  I'll point out one thing to add to your thoughts.  If we believe my measurements, the early tank was 16-17 ft diameter, and and the later one 20 ft diameter.  Assuming both of them did have the usual 9 ft spouts, the early one would have not have been as far back into the hillside as the later one-  the back of the large one would have been 3-4 ft further back into the slope.  
The early tank appears to me to be quite a snug fit to the excavation in the hillside.  I wonder if that had to be reworked and enlarged for the later, larger tank- if so, then the present-day evidence may not be much help with respect to the early tank. The concrete piers may not have been there at all until the second tank went in.

As to the photograph-- I think you're right about the position of the tank bottom, and as to the rest, your interpretation looks reasonable, but I'm afraid it's one of those cases where no matter how hard I squint, I can't see any better.
