RedactedNarrative: On March 31, 2017, I, Game Warden, responded to a call from GSP dispatch at 17:08 hours stating that US Coast Guard had received a call about an overdue boat on the Canoochee River on Ft. Stewart Military Base. As I was about to get off the phone, dispatch advised me that Coast Guard said he may have went fishing at Rodney J Hall boat ramp or Adams boat ramp in Savannah. I told dispatch that I would call Coast Guard and speak with them directly. Coast Guard advised me that they were not sure where the individual had put in to go fishing at and the wife was going to go and look for his truck at the boat ramps. 
  
  I called Wife and she told me her husband's name was Operator and his truck was a 2017 blue Nissan truck with Florida tags. Wife said she was going to go and look for his truck at the two boat ramps in Savannah, she was not sure if he was fishing on Fort Stewart or in Savannah. Wife said that he may be fishing in a pond on Fort Stewart as well.  I called Cpl., who works in Chatham, and advised him of the possibility of a missing boater in Savannah. I called Fort Stewart and let them know of the possible missing boater in either the ponds or on the Canoochee inside Fort Stewart. 
  
  As I was in route to Richmond Hill Fish Hatchery to get our G3 boat to put in at King's Ferry Boat ramp to go up the Canoochee River I received a call from GSP dispatch. Dispatch advised that a Coast Guard helicopter was circling the overturned vessel in the Canoochee River about a mile north of the I-95 bridge.  Coast Guard said the captain was sitting on top of the overturned vessel and  appeared to be uninjured but they were unable to get to him. I advised dispatch that was in route to our boat and that I would be putting in at King's Ferry and going to their location.
  
  When I arrived at King's Ferry, Chatham County Marine Patrol Officer was at the boat ramp. As we were launching the boat Sgt. arrived and assisted with launching the vessel. Sgt. said she would be on stand by at King's Ferry.  Myself and Cpl. went up the Ogeechee River and under the I-95 bridge. I could see the Coast Guard helicopter flying up the Ogeechee River, therefore, I continued up the Ogeechee and did not go up into the Canoochee River. About a half a mile past the I-95 bridge and at about 18:30 hours we located the overturned vessel. The captain was sitting on top of the vessel. Operator boarded our vessel and put on a PFD. Operator said he was uninjured and did not need any medical treatment.  We tied Operator's overturned vessel to a tree on the Chatham County side of the Ogeechee River and returned back to King's Ferry. Operator said he and a friend would recover the boat the following day. Operator said he was wearing an inflatable PFD when the incident occurred. Operator said he hit an underwater object and it flipped his vessel. Operator said the incident occurred at around 16:15-16:30 hours. 
  
  4/2/17- I spoke with Operator and he advised that he recovered his vessel yesterday and it is at Hale Marine in Savannah for repairs. Operator said he was going to be out of town the following week and for me to speak with father concerning repairs to the vessel  and any other information I may need.
  
  4/6/17- I called the father did not have an estimate from Hale Marine. He gave me the insurance policy number and registration information for the vessel. 
  
  4/13/2017- I contacted  father and asked him if he had an estimate for the damage to the boat. Operator said he was about to stop by Hale Marine and would get back with me in a few minutes.  the estimate for the damage was $13,000.
   The underwater object struck by the vessel was not marked. The operator of the vessel stated that he either hit an alligator or a log with his vessel. The operator of the vessel was unfamiliar with that area of the river.
