Chris there is one of these under the 84th St Bridge over the Papio Creek in Papillion. Several years ago 2 High School kids was Kyaking down it after a heavy rain and the water was really high. One made it thru but the other one got caught in the under tow just as it was explained on the video. The Fire Dept went up steam ahead of the dam and block the water off and when it went down they found him caught in the brush at the bottom of one of these. They found him 3 days later. These are very dangerous. EB
