St. Marys River flows will be more natural under Plan 2012



Details
Under Lake Superior Regulation Plan 2012, St. Marys River flows will have a more natural relationship to Lake Superior levels compared to Plan 1977A. Based on the Integrated Ecological Response Model (IERM2), no metrics that were used could make the case that a natural regime would provide greater systemic ecological benefits to the lakeshore ecosystems. However, ecologists believe that restoring natural river flow frequencies is fundamental to sustaining aquatic ecosystems. The more natural flow relationship is also related to the smaller month-to-month flow changes in the St. Marys River under Plan 2012, which is also considered important from an ecosystem perspective.
