Yes, that's definitely a Common Snapper. Baby turtles hatch in the fall and most overwinter in the ground instead of coming to the surface. As soon as the warm days start showing up, you'll see more baby turtles around.
Cool,there's a big old snapper that lives in the creek where I catch minnows in the summer.It sticks it's head up out of the water from time to time and I have seen it's whole body in some shallow areas.I wonder if it has any little ones running around.
This also reminds me that the annual toad crossing will be on hand pretty soon here.
