Most of the time the trap is only 2 to 4 inches underwater, water can rise another 6 to 8 inches before small (10 pound) turtles could not reach air. I have had 20+pounders 15 inches under water and still they can stretch their necks enough to get air. It is surprising how long the turtles neck is. I prefer to trap turtles in streams and rivers. It is amazing how big the turtles are there and how the flowing water gets that bait smell over a much larger area than in a lake or pond. Also most river turtles are eating a lot more fish and crayfish and do not have a constant belly full of vegetation, so they are hungryier. I face the trap downstream and have watched many turtles come upriver as fast as they can go and literally jump into the trap. Caught a turtle this summer and he pooped out a ball of hair, mink hair! Can't say I was sad to see him off to the choppin' block.
Turtle trapping is like fur trapping, its all location, location, location. In a lake or pond, set the shallows, thats where they hunt. In a river or stream set in the shallows just above a deep pool, or at the edge of a deep pool just below a dam. Picture below is the last thing millions of ducks, mink and muskrats have seen
