They love a lot of shallow water, with something they can feed off of. I get a lot on my pond but come Sep. 1 I really don't see much after that. They are not dumb shoot at them a few times they remember.I have called them to the decoys a few times when they are not to far. But they get wise to that too. Around here the dnr will put in a pond for wild life management but only 4' deep.
