That's fine for recreational swimming, but not much good for disc searches, when you swim and feel the bottom with your toes for something hard and round---and hope it doesn't move.
This is, incidentally, a return of the snapping turtles, which we'd seen a year or two ago. Truth is, they're probably always there, and we only see them on these rare occasions*. But until this morning, I'd almost convinced myself they were gone, and had been swimming with less concern.
(* - We only see them when two of them, uh, think there should be more. If you catch my drift. Apparently they're very private about everything else in their life, then come to the surface and thrash around for the world to see their love life.)
