The goal of this project is to continue and finalize Hydrologic Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The project will add representation of point source discharges to the model, compile flow and water quality data for the purposes of calibration and validation. The end result will be an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs.
This project will construct, calibrate, a set of HSPF watershed models covering the entire area of the Lake of the Woods drainage, including the Rainy River watershed. The consultant will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that these models generate predicted output timeseries for hydrology which are consistent with available sets of observed data.
This project will construct, calibrate, and validate an HSPF watershed model for the Lake of the Woods River watershed. The consultants will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultants will clearly demonstrate that the models generate predicted output time series for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
The goal of this project is to construct, calibrate, and validate a watershed model using Hydrologic Simulation Program FORTRAN (HSPF). The project will result in a HSPF model that can readily be used to provide information to support conventional parameter TMDLs.
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.
This project will determine pre- and post-settlement nutrient trends from sediment chronology, fossil diatom assemblages, and from sediment profiles representing human history in the region (i.e., at least 150 years). Project activities include sample collection; sample preparation; diatom analysis; database creation and management; and data interpretation. Sample cores will be taken on the Lake of the Woods in five major bays (i.e., Four-mile, Muskeg, Sabaskong, Little Traverse, and Big Traverse) in the southern basin.
This project will complete the Total Maximum Daily Load (TMDL) study and Watershed Restoration and Protection Strategies (WRAPS) for the Lake Superior North watershed. Two segments of the Flute Reed River are impaired for aquatic life due to elevated turbidity and total suspended solids. The lower Poplar River is also listed as impaired but significant progress has occurred in the last 10 years. A TMDL and implementation plan have been completed for the lower Poplar River impairment. All other waters meet water quality standards and will be considered for protection measures.
Previous research by the St. Croix Watershed Research Station (SCWRS) has identified lake physics (temperature and oxygen) and nutrient recycling (nitrogen and phosphorus) as key drivers of lake algal blooms. SCWRS will conduct monitoring consistent with the prior research efforts by re-deploying three moored buoys to collect data throughout the 2019 ice-free season, including surface water samples. Additionally, SCWRS will deploy an in situ flourometer to measure total algae and cyanobacteria concentrations and will collect and analyze cyanobacterial toxins.
This project is to conduct water chemistry monitoring at two subwatershed sites and two major watershed sites in 2016 and 2017 based on flow conditions, targeting runoff events using protocols defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to Minnesota Pollution Control Agency (MPCA) and used for calculating pollutant loads.
With a perceived increase in the frequency and intensity of cyanobacterial algal blooms in Lake of the Woods (LOW), there has been an increased effort to collect information about the nature of algal blooms, nutrient concentrations and sources of nutrients to the LOW.
This project will address Minnesota Pollution Control Agency (MPCA), United States Environment Protection Agency (EPA), and public comments on draft Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports, preliminary draft TMDL studies, and public noticed TMDL studies and WRAPS reports for the Lower Red River Watershed and the Lake of the Woods Watershed and produce final versions of the TMDL studies and WRAPS reports for each watershed.
The University of Minnesota will develop effective interview questions for community watershed assessments in the Rainy River basin and provide assistance in understanding the data collected through community interviews.
The goal of this project is to development a Total Maximum Daily Load (TMDL) study that addresses all of the non-mercury-related impaired reaches along the Red River of the North (RRN). The TMDL study will provide an analytical and strategic foundation for recommending restoration strategies for impaired waters. This phase of the project will also include civic engagement efforts by providing water quality framework and stakeholder activities for civic/citizen engagement and communication.
The primary objective of this project is to extend the simulation period of the Two Rivers Watershed Hydrological Simulation Program FORTRAN (HSPF) model through 2017 to support future simulation and assessment of the planned Klondike impoundment.
This project is the second phase of updating the Two Rivers watershed Hydrologic Simulation Program FORTRAN (HSPF) model. This project includes calibration of the model and including a proposed impoundment in the model. An analysis of possible downstream water quality impacts will also be done.
