...been on the road; sorry for the slow feedback from my end. Many thanks for the input and ideas.
The topography won't cooperate with routing it further away. The entire wooded area is a "bowl" that slopes in from the surrounding farmland. Ironically, it was this topography that made this such a great pondsite. There is a potential, tho, to run a line from the tank due east into the 1.75 ac meadow area. About 1/2 way across the meadow, the slope flattens and runs downhill as it goes east. By memory, I fear that the uphill from the building site to the meadow is going to be too much for conventional gravity...and I really don't want pumps and the like if I can avoid it. We will be out there soon. I expect that the building site is cleared by now (been working on it all week, I hope)and "things" should be much clearer. I'm gonna get a(nother) hole in my head from scratchin' it on this one. When ya look at an aerial, it seems so simple. Then ya walk the project and face reality.
