These kind of questions crack me up.
Let me repeat your questin so I ubderstand and that way I can give you a solid answer.
1. You found a pond.
2. You have permission to fish the pond.
3. You have transportaion to the pond.
4. I'll assume you have a rod and reel and know how to cast it.
5. Instead of just fishing the pond on your own and experimenting with different baits/techniques, you're going to ask thousands of people WHO NEVER even seen the pond if there's any fish in th pond?
Okay, let me input your questions into my answer machine. Standby, this may take a couple minutes for the appropriate answer. Here it comes, get ready.
The answer is - TAKE AN HOUR AND GO FISH THE POND ON YOUR OWN. You spent hours searching and locating a pond but won't take a few minutes to make a few cast .
Yes, farm ponds contain fish. No, there doesn't have to be a creek, stream or spring for it to contain fish.
