Snappers will walk a mile or more to get to a body of water, especially males during breeding season. So, even though you may eliminate some now, different ones may be there next month.
When that happens, I'll put out some more jugs. They are pretty easy to set up.
Are the turtles you see sunning snapping turtles or are they a different species?
Absolutely snapping turtles. They float out in the middle of the pond with just their heads out of the water. I've caught two so far. There are a few red-eared sliders also. They sun themselves on logs. Not that many of them, though. I caught a dozen of those with a PVC trap a couple of years ago.
Thanks for the link, esshup.
