- Michigan's Natural Rivers Program
Michigan's Natural Rivers program is a river protection effort that protects the natural quality of select river systems throughout the state by regulating their use and development through zoning rules.

The 16 rivers are: Au Sable, Boardman, Betsie, Flat, Fox, Huron, Jordan, Kalamazoo (lower), Manistee (upper), Pere Marquette, Pigeon, Pine, Rifle, Rogue, Two Hearted and White.
