This project describes the approach and methods used to evaluate options to improve Lake Superior outflow regulation. A systematic framework for evaluation was developed taking into consideration the needs, benefits and costs of the various interests from Lake Superior through Lake Erie and the Niagara River affected by levels and flows, and which facilitates public inputs and consideration of climate uncertainty. Performance indicators were developed and used to evaluate impacts of different regulation plans on the interests - hydropower, coastal zone, commercial navigation, recreational boating, water uses and the ecosystem/environment. In addition to the use of hydroclimate and hydraulic models, the IUGLS employed integrated ecosystem response model for evaluating environmental impacts, and the Shared Vision Model which provides consistency in the evaluation of water management options and critical information for Study Board's decision-making.
