A series of whitewater features, even just a few, will make Ann Arbor an attractive destination for whitewater paddlers.
Here is a photo of a single whitewater feature at a drainage ditch in Albuquerque, New Mexico. This features has been used for practice by world-championship-level kayakers. Paddlers all over Michigan would happily flock to the Huron River should similar features be created in lieu of Argo Dam.
