I received a call from a guy who lost his wedding band at a camp by the Redfield reservoir. He was swimming around and had lost weight recently. So what happened? His ring fell off in a area about 100 foot square. After doing an underwater search for about an hour and 45 minutes. I found it in about 18″ of water wedged between 2 rocks. He was really happy to get it back (and so was his wife!).
