FYI, my pond is dug in sand, and is a groundwater pond. When the farmers start irrigating, the pond drops 1" per day. I did ia test with my well, and at 4' below full pool, pumping 25 gpm into the pond nets a retention of 7 gpm. 18 gpm leak back out. I expect that figure to more than double at full pool....

So, to keep it full and not run the well 24/7 I figure I need a well that will supply more than 100 gpm. The aquifier will handle it, just gotta properly size the well. The aquifier here is between 90 and 110' down.

That's why it's important to try like heck to seal it like a bathtub with the plug in the hole.
