This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
The goal of this project is to extend existing Hydrologic Simulation Program FORTRAN (HSPF) models through 2017 for the following major watersheds: Redwood, Cottonwood, Watonwan, Blue Earth, Le Sueur, Pomme de Terre, Minnesota River-Headwaters, and Lac Qui Parle watersheds.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
This project will develop the Pomme de Terre Watershed Total Maximum Daily Load (TMDL) study for the second round of the 10-year watershed approach cycle in the Pomme de Terre watershed. This phase of the project will address 4 stream impairments and 3 lake impairments and produce a draft TMDL document. A second phase may be needed as the stressor ID report identifies more stream reaches with TMDL relevant stressors.
Certain stretches of the Pomme de Terre River have been identified as impaired. This project will quantify the reductions in pollutant loading that would be necessary to bring water quality in the impaired stretches to an acceptable level. It will also identify strategies that would improve water quality in these impaired stretches. Some funds will support public input activities into the Pomme de Terre River watershed management plan.
The goal of this project is to extend through 2016, calibrate, and validate the existing watershed model using Hydrological Simulation Program FORTRAN (HSPF) for the Pomme de Terre River Watershed. The contractor will produce an HSPF model that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) studies.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
