Man, this must be an enigma wrapped in a mystery !...didn't know I'd open up such a long thread !...
My pond was dry enough to walk on for about two weeks...forgot who asked if there was a puddle left...
After the rains a couple of weeks ago I may have figured it out...about a mile from my pond there is a small creek...it does hold water year 'round and is "downstream" from me...well after the heavy rain I spotted hundreds of bullhead fry swimming in puddles in my pasture which had to have come from my pond...only thing I can figure out is at some point in time the parents of the ones in the pasture worked their way up from the creek during a period of heavy rain...don't know about the bass or green sunfish, suppose the same theory is plausible...
