RedactedNarrative: On Monday May 6, 2019 at approximately 12:30pm I was dispatched to a reported boating incident on the Duck River in Humphreys County around the Dyer Road Boat Ramp. I arrived at 1:00pm to the Dyer Road Boat Ramp where I found the Humphreys County Rescue Squad who had been involved in the incident. Operator stated that at approximately 9:30am he had put his boat in at the boat ramp and operated upstream just North of the ramp and first shoals. He attempted to anchor his vessel in swift water to fish with a black mushroom style anchor tying it off to the bow eye of his vessel. His boat continued to drift downstream and would not catch so he started the engine and tried to maneuver himself in a better position. The swift water turned his boat around and the jet intake sucked the anchor line up inside the intake fowling the motor. The anchor line then pulled the stern of the boat under water and began to swamp. Operator was able to put his lifejacket on and call for help before going into the water and floating downstream. He was able to swim to a tree limb and hold onto it. His vessel drifted downstream as well. Humphreys County Rescue Squad retrieved the vessel and towed it back to the boat ramp.
