Lake Superior is one of our nation's greatest resources.
The lake is a unique waterbody in many ways given its large size, geographic location and long water residence time. The Great Lakes States of Michigan, Minnesota, Wisconsin and the Province of Ontario have developed a cooperative plan to collectively protect and restore the integrity of the Lake Superior Ecosystem. As a result, numerous efforts are ongoing in an effort to obtain these objectives. One such effort is being coordinated through a cooperative effort between the University of Michigan Air Quality Laboratory, the Trustees of the Lake Superior Basin Trust, the Michigan Department of Natural Resources and the Wisconsin Department of Natural Resources. For its part, the University of Michigan Air Quality lab is taking a basin-wide, total ecosystem approach to obtain a better understanding of the cycling of mercury in the Lake Superior region.
