We have both snapping and painted turtles in our immediate area with one particular female snapper. She came up the east lawn a couple of years back to lay her eggs.
The other issue I've noticed is that the baby snappers for some reason will leave the lake area to head towards a more swampy area. The problem is the road between. Most get runover as people can't see them with the autumn eaves falling. I helped this one little guy, no bigger than my thumb, to the other side.
It would be nice to create an area where they are more protected.
