The world kayak waterfall record was set in 2009, when American kayaker Tyler Bradt successfully paddled the 189.5-foot drop of Palouse Falls in Washington's Palouse Falls State Park. As of September 2013, Bradt still held the record for the longest-ever waterfall drop traversed in a kayak.
It took Bradt, an experienced kayaker, less than 4 seconds traveling at almost 80 miles per hour to complete his journey down the waterfall. He emerged from underneath the falls with no injuries or other damage to himself or his kayak. The next highest waterfall elevation in the list of kayak waterfall records is 128.6 feet.
