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.
Yosemite Falls is the tallest waterfall in Yosemite National Park; this waterfall consists of three separate components and spans 2,425 feet. Each of these three components can be considered a separate waterfall, but the total height of the falls is taken as a single measurement. This waterfall is one of the top five tallest falls in the continental United States.
