Maximizing storage in Island Park Reservoir, Idaho under varying hydrologic regimes and environmental flow requirements

This report details a model that uses a nonlinear penalty function in a linear reservoir optimization model to identify a monthly reservoir release strategy that maximizes end-of-water-year storage in Island Park Reservoir, while satisfying habitat and flow requirements for fish and anglers. Using historic hydrologic data, I explore how strategies for reservoir release, storage, and irrigation reduction change across varying hydrologic regimes (wet, average, dry) and environmental flow requirements (800, 1000, 1200 cfs).
