The victim and his father were fishing near mile marker 497.0 on Chickamauga Lake.  The victim told his father he was hot, and jumped in the lake to cool off.  He started having difficulty swimming back to the boat and asked his father for help.  His father jumped in to help, and the boat started to drift away.  They yelled for help, and two nearby fishermen responded to help from approximately 200 yards away.  When they got to the father, the victim had already went underwater.  The two fishermen pulled the father over to the bank, went back and got the boat and called 911.
