A series of 4 videos showing aggressive flow of water in the Canadian River on August 21, 2007. This location is on the north bank of the Canadian River, just south of Norman, Oklahoma. Oklahoma has not had sustained rainfall since 2007. 2007 was a very wet year across much of the state. In fact, some of that rainfall was associated with the remnants of hurricane/tropical storm Erin, which reorganized over Oklahoma and exhibited counterclockwise rotation of the atmosphere. The rotation was not classified as a "hurricane" because a hurricane cannot form over land...by definition!
