I've only seen shallow creeks. Go to Meramec SP for swimming.
No.
Johnson's Shutin is about a 30 min drive from Hawn. That's a really cool place to get in the water. And Elephant Rock is pretty close to it as well. You can't swim there but since it's so close you should go see it.
Nothing deep enough to swim in there. Can get your feet wet to cool off is about it.
