Ecosystem Technical Working Group Synthesis and Summary

Scudder Mackey;
Describes the overall strategy and methods used to assess potential ecological implications of proposed Lake Superior water level regulation plans. The St. Marys River provides critically important wetland, fish spawning, and nursery habitat for many species in the upper Great Lakes. An approach was adopted that focused on assessing ecosystem vulnerabilities to changing upper Great Lakes water level regimes. The objective of this approach is to identify water-level ranges and threshold criteria that minimize adverse impacts to biotic communities and ecosystem function, i.e., a range of water levels and water-level variability that supports diverse biotic communities and ecosystem functions. The objective is to describe for the ecosystem interest group how the overall strategy and methods were implemented and to identify key technical and management issues encountered along the way.
