Hydrologic Simulation Program FORTRAN (HSPF) Modeling Lake Superior Watersheds Phase 1

The goal of this project is to construct, calibrate, and validate two Hydrologic Simulation Program FORTRAN (HSPF) watershed models: Lake Superior North and Lake Superior -South. The contractor will produce HSPF models that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that these models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data. The contractor will deliver all modeling files, several memorandums which are described in the Measures and Outcomes section below, and a final report documenting model calibration and validation and supporting statistics.
