The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models simulate sediment erosion and transport, however these models periodically need to be adjusted to be consistent with the most recent sources of information regarding sediment distribution and loading rates. The goal of this project is to refine the sediment source partitioning and simulation in the Minnesota River basin using all relevant available sources of information.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models, which simulate flow and pollutant transport, need to be refined to be consistent with the most recent external sources of land use, hydrologic response, and surface flow attributions. The primary goal of this work is to refine the hydrologic calibration in the Minnesota River basin.
The Lake of the Woods (LOW) Total Maximum Daily Load (TMDL) study will: (1) identify water quality goals for the Minnesota portions of the LOW/Rainy River Watershed; (2) recommend nutrient allocations to achieve TMDLs where waters do not meet standards; and (3) provide opportunities for stakeholders to engage in the process of watershed-management planning to adopt protection and restoration strategies. The project will include existing in-lake and watershed model updates, TMDL component development, restoration plan development, and public participation.
This project supports activities by Minnesota Pollution Control (MPCA) Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting Total Maximum Daily Load (TMDL) studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
The Nitrogen Fertilizer Management Plan (NFMP) recognizes that existing best management practices (BMPs) may not adequately protect the groundwater from nitrate contamination in some geologic sensitive areas. The NFMP introduces the concept of alternative management tools (AMTs), which are advanced practices that may be required to protect groundwater or mitigate groundwater contamination.
The study will assess existing phosphorus data records and create a model to explain phosphorus loading into the Red River of the North. Studies have found that the majority of nutrient loading in the stream located in agricultural areas occurs with sediment loading since nutrients are typically bound to sediment particles.
The overall goal is to develop a Watershed Restoration and Protection Strategy (WRAPS) report and Total Maximum Daily Load (TMDL) study that will address water quality stream impairments and maintain or improve water quality of streams throughout the Pioneer Sarah Creek watershed, which is part of the North and South Fork Crow major watersheds. The study will identify sources of pollutants to the streams and develop restoration and protection strategies for the streams in the Pioneer-Sarah Creek watershed.
