| Detailed Description: | Todd Smith, 28, was a very experienced boater who had paddled the North Chickamauga Creek,
“On “When we checked the gauge at Possum Creek that Sunday the reading was 5 feet. Since our previous runs had been at the mid-3 feet zone, we decided that this was a dangerous level. We left to scout other runs, then returned two hours to recheck the gauge. The river had dropped a foot. Since our previous runs had been too shallow at the bottom, this level might be just right. “We shuttled to the top. The big 30-foot waterfall was run with no problem. We ran a rapid we call Holy Cross with Todd having the cleanest line through. Next we came to the two 20-foot double falls. Jon ran a perfect line on both. Eric ran the top falls twice but walked the bottom one. The rest of us had no problem walking these drops, setting up safety for the runs on both falls along the route, “Once past the major drops we flew down an easier section for several miles. The rapids were mostly Class II- “As my group approached an area that had a small drop that had caused me trouble on a previous run. I could see that efforts were being made by the first group to free what I assumed was probably a stuck boat, so we proceeded to eddy out just upstream. It never entered my mind that my great friend was in a life-threatening situation. The area of the drop has a nasty undercut on river left. We walked this rapid until a tree that had caused me trouble had washed out. “Evidently the four kayakers had eddied out and one by one ran this squeeze. The creek here is forced into the right bank where several large tree limbs were overhanging the water. These limbs, along with sharp eddy lines, caused three of them to flip, but they all rolled up okay. A short pool then narrows into the 4-foot drop where I had been stuck against the tree previously. The creek goes from being 20-30 yards wide to about 5 to 6 feet, creating tremendous pressure against the undercut. Jamie rolled up and went through forward. Eric rolled up and went through backwards. “Todd rolled up but his paddle, a lightweight graphite model, broke in half. Unable to steer or stroke for speed he was pushed into the undercut. His boat didn’t flip but was pressed up against the undercut rock. A log was under his cockpit and the force of the water bucked the deck of his creek boat onto his legs and wrapped it around the log. The bulkhead was lying on its side inside the boat. Any fear that we had failed our friend in rescue were allayed by the fact that the rescue squads needed 30+ men and over 4 hours to extract him. Basically, the water dropped enough for them to get him out.
We thank the agencies that responded to our call to this remote area.

| Conclusions: | ANALYSIS: 1. (Walbridge) The accident was unusual in that gear failure played a central role. A broken paddle, combined with a flip, left Smith helpless above a dangerous hazard. The paddle, a lightweight graphite model, was a replacement for one that he had broken previously. Graphite tends to shatter, and is probably not durable enough for creek boating. This incident reminds us that lightweight gear in general should be used with caution in difficult whitewater.
2.(Shoun): Should this rapid have been run in the first place? After running all the big drops upstream this “squeeze drop” didn’t seem too bad, especially since the tree had washed out. I’d rate it a Class
3. (Zitzow) The mechanism of the accident was as follows: Todd’s stern tagged the tree, causing him to flip. He rolled, but his paddle was broken and he was pushed into the squeeze drop backwards. The drop was only 3 feet high, but was a left to right move with a bad undercut on the left. His boat jammed in the slot, then folded at the cockpit around a 6 inch diameter log that was jammed vertically in the chute. The boat pinned Todd in his boat facing upstream. He was completely submerged and not visible to rescuers.
4. (Zitzow): The wrap started in the cockpit area, between the sides of the seat and the start of the wall. The crushing of the cockpit held Todd’s legs in his boat, trapping him. The sides of the seat did not crush, but the front wall did. It stayed within its tabs, but bent into an “S” shape. On larger cockpit boats there is little internal support in this area, and we need to think about what can be done to strengthen it.
5. (Zitzow): This accident should cause everyone to pay more attention to the danger posed by small diameter logs. The one that pinned Todd’s boat was quite narrow, but could not be moved by a Z-drag. With some of the new moves like jumps and slides, I think some people have developed a cavalier attitude. We must remember how dangerous they really are.
