This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
This project will develop and execute three point source related scenarios for the Chippewa River watershed using an existing HSPF watershed model. This project will also support the review of the HSPF Modeling Guidance Document.
This phase of the project will complete a TMDL for the impaired reaches of the Snake River Basin. The project includes development of a Unit Area Load model for nutrient sources, a spreadsheet version of a BATHTUB lake response for four lakes, and a bacteria source assessment. Contractor will also provide all stream channel data as a spreadsheet database and in GIS.
