Minnesota River Basin Watershed Achievements Report 2015 Project involving multiple watersheds HSPF Minnesota River basin resegmentation 2010-2012 This project resulted in the successful temporal extension of the simulation period through the year 2012, resegmentation and recalibration and validation of the Chippewa and Hawk Creek-Yellow Medicine HSPF models. These fully functioning calibrated and validated executable models simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, DO, BOD, and algae at the 12-digit HUC subbasin scale (or finer) within the specifications formulated by AquaTerra Consultants for the EPA. Additionally, these models were reconnected to the Middle Minnesota River watershed HSPF model. The Chippewa River, Hawk Creek, Yellow Medicine River, Redwood River, Cottonwood River, Watonwan River, Le Sueur River, and Blue Earth River watersheds are all connected to the Middle Minnesota River watershed and subsequently the Lower Minnesota River watershed models. These connections recreate a basin-wide HSPF model for the Minnesota River Basin. Goals • Extend the simulation period of the Chippewa River, Yellow Medicine River and Hawk Creek watersheds through 2012. • Reconnect the models with the Middle Minnesota River HSPF model. • Reestablish a seamlessly executable linked Minnesota River Basin model. Results that count • The Yellow Medicine River, Chippewa River and Hawk Creek watershed models now run through the year 2012. • Outputs from the Yellow Medicine River, Chippewa River and Hawk Creek watershed models are now read as inputs by the Middle Minnesota HSPF models. • A Minnesota River Basin HSPF model has been reestablished. Ten HUC 8 models can be run in sequence to model the entire Minnesota River Basin.

Watershed Minnesota River Achievements Basin Report 2008 Watershed Achievements Report Statewide 2015 Project involving multiple watersheds HSPF Upper Minnesota and Lac qui Parle Rivers Watershed Phase 1 The goal of this project was to construct two executable HSPF models for the following two watersheds: Minnesota River – Headwaters (07020001) and Lac qui Parle River (07020003). The contractor used the Minnesota River HSPF model applications already developed by Tetra Tech as a starting point and refined the model construction. The contractor produced HSPF models that, after calibration and validation, will readily be used to provide information to support conventional parameter TMDLs. Goals • The contractor will compile available existing data for the binary and FORTRAN input files. • The contractor will construct the framework of two HSPF watershed models which are executable. • The contractor will summarize and communicate the results. Results that count • The contractor participated in calls and an information gathering meeting in the watershed. • The contractor submitted the executable files and supporting files. • The contractors submitted a memo summarizing the construction of the two watershed models.
