High & low levels

A Reference to determine whether measures within the Great Lakes Basin can be taken to regulate the water levels of the Great Lakes to reduce extreme low and high water stages.

The IJC concluded that water level fluctuations in the Great Lakes are primarily caused by nature and only a limited reduction in the range of water levels is practical. Protection from high and low water levels cannot be achieved through lake regulation alone. The IJC recommended further study of the environmental and regulatory effects of regulation, diversions, consumptive uses, and the use of improved meteorologic, hydrologic and hydraulic networks in the basin. The governments responded with several new references which include a study of Lake Erie Regulation(Docket 103); Great Lakes Diversion and Consumptive Uses (Docket 104); Great Lakes Technical Information(Docket 105) ; Great Lakes Levels Advisory Board (Docket 106).
