What are the limits of regulation?

The ability to modify water levels and flows in the upper Great Lakes system is not limitless. Rather, Lake Superior regulation is limited by the capacities of the control structures on the St. Marys River, the water supplies received by the lakes, other physical limits, and by the often conflicting objectives of the various interest groups. To explore the limits of Lake Superior regulation, during the earlier stages of plan formulation, the Study highlighted three “fencepost” plans to identify the boundaries of what could be done for the key interests, such as hydroelectric generation, commercial navigation or coastal zone interests, through the regulation of Lake Superior. These fencepost plans were not designed to be viable alternatives to the existing regulation plan but rather to illustrate the impacts of considering a plan that serves the specific needs of a single interest or group of like-minded interests.
