The Au Sable and Manistee River Watersheds span the breadth of Michigan’s Lower Peninsula. Both watersheds contain areas that are vital to the agricultural and economic productivity of Michigan, as well as some of the best recreational opportunities that the Lower Peninsula has to offer. MSU has created a monitoring program in this area in order to better understand the complex feedbacks that occur in such a system, and to provide a baseline that can be used to understand the impact of future changes to the land and water resources in the watersheds.
