This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
The goal of this project is to simulate up to ten scenarios using the recently completed Hydrologic Simulation Program FORTRAN (HSPF) model for the Mississippi River–Lake Pepin (MRLP) watershed. The mode will be used to investigate a variety of management scenarios to support further planning work and implementation in the watershed. Model scenarios are being developed to inform 1W1P planning activities and future implementation.
The goal of this project is to complete the construction, calibration, and validation of a Hydrological Simulation Program – FORTRAN (HSPF) watershed model for a portion of the Mississippi River-Lake Pepin watershed.
In previous phases of work, a Hydrologic Simulation Program FORTRAN (HSPF) model of the Zumbro River Watershed was developed to simulate hydrology and water quality for the 1995-2009 simulation period (Phase I), applied to evaluate various management scenarios for reducing sediment and nutrient loading (Phase II), and used to develop Total Maximum Daily Loads (TMDLs) for impaired stream segments and inform development of a nutrient TMDL for Rice Lake (Phase III).
