I did some digging and I found this article with more info:

Thanks, that was neat! I've seen a very large (about 2 feet across the shell) snapping turtle in a large (more than a square mile) inland lake in Michigan, and someone I know has pulled a pike more than 4 feet long out of an inland lake (those two critter types are probably responsible for most of the ducks with a foot missing) -- it wouldn't surprise me if even larger ones exist in Lake Michigan, and they have the advantage of being local species.
