U.S. National Whitewater Center - world's largest man-made whitewater facility (claimed)

The U.S. National Whitewater Center in Charlotte is described by its operators as the world’s largest man-made whitewater river and whitewater rafting facility. The outdoor recreation center opened in 2006 and occupies a large site offering whitewater rafting and kayaking alongside activities such as rock climbing, zip lines, and extensive mountain-bike and hiking trails. The facility uses engineered channels and pumped flows to provide sustained whitewater for commercial rafting and paddling programs.
