If they are older ponds, I'm 99.9 % sure they will have some sort fish present. We've debated this topic many times, so odds are 1) An individual put some fish in there. 2) Birds transplanted them somehow. (highly debated topic...although I have personally witnessed a blue heron spiking a crappie, and relocating it to a shallow area for later consumption). 3) Tornados sucking up fish, lol reports have stated perch flopping around in front yards. 4) runoff...simply coming in from a higher water source overflowing. I think you should set a minnow trap, then bait up a work too...reporting back
