RedactedNarrative: On July 8, 2018, the victim and the victim's spouse were kayaking on the Jefferson River. They launched at Sappington Bridge, south of Three Forks, MT. Each individual was on a separate kayak. Between 11:00 and 11:30 they came to a diversion dam which had water flowing over the top of the concrete wall. The current was too strong for the kayakers and they were forced to go over the diversion dam. The victim's spouse was able to maneuver over the diversion dam. The victim's kayak turned sideways as it neared the diversion dam. The victim and his kayak rolled when the kayak came in contact with the diversion dam and the victim went upside down in the water. After several seconds, the victim reappeared and was able to make his way to a nearby sandbar on an island before he became unconscious. The victim's spouse and other recreationists nearby immediately began CPR. Medical staff continued CPR for several minutes prior to loading the victim into an ambulance. The victim was then transported to Bozeman Health, where he was pronounced dead at 14:14. The cause of death is still under investigation by the Gallatin County Sheriff's office at the time of this report.
