I can tell you that most, if not all, MS Delta catfish ponds use well water to pump up. I know of a couple in East MS that had pumping permits for Catalpa Creek, but most use wells.
Funny you mentioned Isola (or even know where it is!), as that’s where I grew up on a row crop and catfish farm.
*well now it says West AL instead of Isola, MS*
While I was driving to Birmingham this morning my buddy and I were talking over the phone about this very thing. Filled with well water... We both love us some farm raised catfish.
