Larry - Thanks for finding and posting Carlos's photos. I, too, have looked over at the base every time I went by. Nice to see the close-ups. There are now some small private structures south of the tank (beyond the tank in the first photo), so obviously private land.
Looking at the Don Rogers photo put up by Dave Grandt, just above, it appears that the topography immediately behind the tank is different. Nor is there room for the spur track. But the distant hillside looks reasonable. Perhaps the pond dam was rebuilt after 1938?
