Comprehensive Assessment of Impact of Anthropogenic Changes to the Upper Great Lakes System on Michigan-Huron and Erie Levels
- Frank H. Quinn;
- A holistic assessment was made of all factors leading to the reduction in water level fall between Lake Michigan-Huron and Lake Erie over the past 120 years. Factors examined include: glacial isostatic adjustment, physical changes in the Great Lakes outlet channels, major water diversion projects, and outflow regulation. Computer simulation was made of historical water levels and outflows that would have occurred given actual historical water supplies, present channel outlet regimes and diversions, and lake outflow regulation; and these were used as a basis for comparison to assess the impacts of anthropogenic changes over time.
