Plan 2012 will be more robust and provide important benefits compared to Plan 77A

In choosing to recommend Lake Superior Regulation Plan 2012, the Study Board developed and applied a number of decision criteria and other evaluation metrics. No single regulation plan developed during the plan formulation and evaluation process was uniquely superior to all the other plans – there were tradeoffs that were made by the Study Board between economic performance, reliability under extreme lake levels and ecological performance. In all instances, the differences in economic performance among the final set of plans was very small – well within the range of measurement error. As a result, the Study Board focused on the relatively small difference among plans regarding ecological metrics and performance under extreme conditions – conditions that might materialize under a variety of future climate-driven sequences. The ultimate driver for decisions became “which plan is the most robust”, and will perform the best under a range of extreme conditions. So while no plan outperformed every other plan for all nine decision criteria and NBS sequences, Lake Superior Regulation Plan 2012 was found to meet all the Study Board’s decision criteria and is considered to be more robust than Plan 1977A, performing better for most NBS sequences and never significantly worse, and providing benefits related to maintenance of Superior levels, the environment, economic benefits and ease of regulation
