What are the main benefits of the new regulation plan?

After many iterations, the final candidate plans evaluated by the IUGLS showed significant differences in levels and outcomes only during extreme water supply conditions, attesting both to the soundness of Plan 1977A and the influence of conflicting objectives that made it difficult to provide benefits in one area without adversely affecting another. 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.
