Rex, your project is an inspiration. I live on 40 acres of woods in north Midland County, maybe 30 miles north of you.
My present dilemma is a pond that won't hold water. It's sand all the way down to perhaps 20 feet (originally). No clay in sight. You have to go pretty deep before you hit clay in this part of the county. The previous owner didn't want a pond so much as he wanted fill sand to build up the house site. The guy who dug the pond tells me he tried to talk the previous owner into lining it with clay.
The "pond" is low enough on water and close enough to the house to be more of an eyesore than an asset. So I'm wrestling with the decision to
a) line it with clay (which would have to be hauled in),
b) put in some kind of very expensive liner,
c) fill in the pond and expand the orchard, or
d) live with it the way it is.
But congratulations on your progress and thanks for the pix. You're an inspiration to the rest of us!
