The goal of this project is to apply the Hydrological Simulation Program FORTRAN (HSPF) model to evaluate scenarios to support potential management actions and implementation in the watershed, construct Total Maximum Daily Load (TMDL) studies, and to develop a conceptual site model of the lakes for understanding phosphorus release.
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 MPCA, in partnership with the Vermillion River Watershed Joint Powers Organization, contracted with Wenck Associates, Inc., to develop the Stressor Identification (SID) Report; and develop the necessary models for the Vermillion River Watershed Restoration and Protection Strategies (WRAPS) as part of Phase I. The final Vermillion River Watershed SID report discusses all of the analysis that was done in the watershed to identify the primary stressors causing the fish and macroinvertebrate impairments in the watershed.
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 MPCA has selected the Soil and Water Assessment Tool (SWAT) watershed model to simulate watershed hydrology and water quality to assess various restoration scenarios in the Little Cannon River watershed. The SWAT model is an important tool in developing an understanding of existing conditions and simulating conditions under various management scenarios to inform the development of implementation strategies and plans to restore and protect streams and lakes.
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.
The Zumbro River watershed HSPF model will be refined to include recent data and information as well as evaluate various management scenarios to inform the most effective actions for reducing sediment and nutrient loading and improving water quality. Specifically, to provide the foundation for the Lake Zumbro Phosphorus Total Maximum Daily Load (TMDL).
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).
