Jim,

without another object of known dimensions in the photo to scale from, I can't do an entirely confident job with the tunnel gulch (TG) tank.  Best I can do probably is to assume the feed outlet to the spout is the usual 12' above the ground.  Using that as a scale, that gives about 16,000 gal for the capacity of the tank (about 15' diameter by 12' tall).  The posts are just about 12x12 inches in that scale, so that does give some confidence in the numbers. It's interesting that the diameter may well be the same as the Blackhawk tank.  The Morrison tank has the same proportions as TG , and by the same 12' spout height scale it comes out also to 15' diameter and 12' tall.

So to summarize, all three may be the same 15' diameter, with  M and TG 12' tall while BH is 15' tall, and the 3-bent base may be a common feature- I bet Keith is right. Notice though, that in the photo Chris posted of the Blackhawk tank, there is no frost box and the diagonal bracing is much more complex than in Jim's first photo of BH and the one of TG, which look to be alike.  I can't make out much about the structure of the Morrison bent bracing from that photo, but it looks to me as if it is complex, and I can't see a frost box.

cheers,
John
