Lake Superior Fencepost Plan Development
- Three fencepost plans were developed early in the IUGLS to explore the possible bounds of Lake Superior regulation. Fencepost plans are not realistic as they are designed to favour one objective no matter the harm to other interests, and as a result they fail to meet Boundary Waters Treaty and IJC Orders of Approval requirements. However, they allow us to explore the range of levels and flows that are physically achievable given a sequence of water supplies and assuming existing capacities of the St. Marys River regulatory works. The "Superior for Michigan-Huron" plan uses Lake Superior as a reservoir to reduce the water level range on Lake Michigan-Huron. The "Superior for Superior" plan aims to keep Lake Superior as close as possible to its monthly long-term average levels. The "Dependable Flow" plan has the objective of providing dependable flow for hydropower purposes. Results showed that even these extreme plans have limited ability to meet singular objectives.
