Welcome to the Forum #7!!! We're happily getting several new members from your area!
The pictures are hard to get a good perspective of how the land lies, but it sure is purty!
It stinks that you may have one of the "less than exuberant" NRCS Agents. Do you know if there is any significant amounts of clay in the hills surrounding your pond sites? That may be the key, along with budget and desire as to whether the dream stays alive or not.
Personally, I wouldn't consider Dam site B because of the reduced inflow, but mostly from the fear of erosion from heavy runoff in the draw behind it.
Except for the supply line route of your well, there should be no issue there.
I can't imagine that if there are two culverts in the road draining onto your property that your watershed is only 2 acres, unless the culverts would not drain into the pond....Unkown/uncontrollable watershed contaminants is always a concern to think about....Try to find out what is in the watershed Trees, Cows, Hogs, Radioactive Green glowing sunfish, etc).
Are there ponds near you? Do they hold water? Talk to the pond owners and see what problems they ran into and ask who built the ponds. Also talk to local well drillers...they will know if good clay is there and how deep it may be.
All in all, it is a beautiful site for a pond and maybe a well and liner could become an option if a natural pond isn't feasible.
