RedactedNarrative: On June 16, 2022 at approximately 1100 hours Occupant 1, Occupant 2, and Operator 1 started a fishing float trip on Rock Creek in Granite County, Montana. All were wearing PFD''s. They started at Bohrnsen Bridge in a gray Odyssee Raft and were to take out at the boat launch near the Dalles. It was a nice day, water conditions had cleared up, fishing was good as the Salmon Flies were in the air, and discharge levels had dropped significantly. After floating and fishing for awhile, they entered the section of Rock Creek near where Hogback Creek flows in. This section of Rock Creek braids significantly making it difficult to determine which channel to take or which one is the main channel. The channel they chose was shallow on river left but deeper and swifter on river right. Operator 1 was having trouble moving the boat because of the shallower water on river left and the raft was swept into the swifter deeper water on river right where a hazardous log jam of 10"-12" Aspen trees was.
  
  The raft collided with the log jam broadside (right side of the raft) and the upstream tubes (left side of the raft) began to take on water causing the raft to start to flip over due to pressure from the current coming into the boat. Occupant 2 was able to jump over the raft tubes onto the log jam before the raft flipped. As the raft flipped Operator 1 was thrown into Rock Creek and was swept under the flipped raft. Occupant 1 was able to hold on to the upside down raft on the upstream side keeping his head above water. 
  
  Operator 1 did not resurface after going underneath the raft so Occupant 2 attempted to push the raft through the log jam telling Occupant 1 to hold on. Operator 1 at the time was stuck under the raft unsure of what was holding them and was struggling to get loose. Occupant 2 was finally able to get the raft pushed through the log jam after a minute or two of struggling. Operator 1 ended up free of the raft and log jam after Occupant 2 had pushed the raft through the hazard. Operator 1 was wearing waders of which had been pulled down to their wading boots creating resistance in the water but was eventually able to get ahold of some brush near some slower water and get to shore. Occupant 1 was still holding onto the raft as it exited the log jam and began quickly floating downstream.
  
  Occupant 2 was able to quickly check on Operator 1 to make sure they were alright. Operator 1 acknowledged they were ok so Occupant 2 began to run downstream to check on Occupant 1. Last time Occupant 2 had seen Occupant 1, they had let go or become free of the raft somehow. Occupant 1 was swept downstream out of sight. 
  
  Occupant 2 continued to run downstream where they were picked up by another float group. Occupant 2 floated downstream with the other group to find yet another group of people who had pulled Occupant 1 out of Rock Creek onto a gravel bar. Occupant 1 was very blue, unconcious, and had no pulse at that time. Occupant 1 was then ferried across the creek to a boat launch just below the Hogback where CPR was attempted by several bystanders. During CPR it was noted that a lot of water was coming from the mouth of Occupant 1 having to be turned to their side several times to keep water coming out of their lungs. Operator 1 was eventually able to run downstream along the main Rock Creek Road and located the group conducting CPR. CPR was conducted on Occupant 1 for approximately an hour before a Granite County Sheriff''s Deputy and Coroner arrived on scene. Occupant 1 was pronounced deceased at approximately 1410 hours and cause was declared as drowning.
