I believe they KNOW when the turtles are gone and it is safe again....niether my geese or the ducks would go into the pond after the first snapper attacked.
Several years ago I had to drain my pond to get rid of ALL the turtles in it...and there were some really big ones!
Then last year with the draught my neighbors pond dried out and his turtles came down to my pond. I shot 4 of them with a 22 over a week's time and the ducks and geese then went back into the pond, cautiously at first.
Sounds like you have quite a few turtles in your pond.
