Upper Minnesota and Lac qui Parle Rivers Hydrologic Simulation Program FORTRAN (HSPF) Modeling - Phase 1

The goal of this project is to construct two executable Hydrologic Simulation Program FORTRAN (HSPF) watershed models for the Minnesota River Headwaters and Lac qui Parle watersheds. The contractor will use the Minnesota River HSPF model application already developed by Tetra Tech as a starting point and will refine the model construction based on the details in this work plan. The contractor will produce HSPF models that, after calibration and validation, will readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs).

This project will result in the successful development of two preliminary executable watershed Hydrologic Simulation Program FORTRAN (HSPF) models. These executable models will later be calibrated and validated to simulate hydrology at the 12-digit HUC subbasin scale (or finer) within the specifications formulated by AQUA TERRA Consultants for the MPCA. An executable HSPF model must be submitted for each of the following 8-HUC watersheds: Minnesota River Headwaters and Lac qui Parle.
