That old original post about says about it all, except for the size of the pond. I was overly optimistic in predictiing the eventual size. I'm still only guessing,(no actual measurements due to very irregular shaping, but mental measurements in the form of - well, that looks about like a couple of football fields in that area, another in this area, maybe a half over there, etc,etc) so, I'm guessing around 5 acres.
The larger body of water near the dam area cannot be seen in the pic. The water area upstream of the dock begins to narrow considerably.
