RAH - Thanks for all of that additional information!

It is amazing how similar our soil profiles are considering the distance between our properties.

Our sand veins also act as springs. However, our surrounding topography is pretty flat. The potentiometric surface of the spring water is just barely above the sand veins.

I would have to dig my ponds 18' deep to have a 12' max. depth below the springs that are 6' below the current ground level.

Our creek has gone up almost a foot in the last two months, with essentially zero rain in the watershed. When the trees and tallgrass prairie go dormant, the cessation of transpiration greatly increase the net flows of the springs to the creek! It kind of freaked me out the first few dry falls.
