RedactedNarrative: The fatal boating incident occurred on May 14, 2016 at 6:18am below Cheatham Dam.  The accident was recorded on Cheatham Dam's lock monitor video.  Three men were in a 16'8''ft fiberglass Javelin Bass boat fishing below Cheatham Dam.  The driver and owner of the boat was Operator#1, uninjured passenger aboard was Passenger#1, and deceased passenger aboard was Victim#1. The driver stated he drove the boat too far up into the breaking current line and the boat was pulled forward towards the dam's spillgate. The driver stated the vessel had no mechanical problems at the time of the accident. The boat came into contact with Spillway Gate #4. It was held in its hydraulic and it started to flood.  The boat then flipped over in the turbulent water and all 3 men were thrown overboard. The driver was rescued by dam construction workers who pulled him up onto the dam above. Passenger#1 was pulled under for a moment and then discharged downstream where he was rescued by a nearby fisherman in another boat.  All 3 men were wearing PFD's at the time of the accident; however the deceased victim's PFD came off of his person.  It was believed that the straps were not buckled properly.  He was over 300 pounds and the PFD recovered which he was wearing at the time of the accident was an adult size Medium. He also was not a swimmer.  Recovery personnel were able to locate a specific search location by way of cadaver dogs and side/down scan sonar.  The area was below the Dam's lock wing-wall and a Barge tie off pier.  Victim#1's body was recovered the following day May 15, 2016 at 4:43pm by Ashland City Fire and rescue boat approximately 50 yards from search area.
