This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
This project will build network and the skill set of local resource professionals to do effective civic engagement work for water restoration and protection in Southeast Minnesota. The cohort will be administered through the Southeast Minnesota Water Resources Board (SE MN WRB) which is an area wide Joint Powers Board (JPB) established to help improve and protect the water resources of the area through coordinating local water planning efforts. This JPB has successfully administered water quality grants in the past that have positively impacted the water resources of this region.
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 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.
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 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.
This project will build a working watershed SWAT model that can readily be used by the MPCA to provide information to support conventional parameter TMDLs and to identify critical areas for BMP installation/evaluation that can be supported by the efforts of the local Farmer Led Council as well as other land owners within the Mississippi River-Winona 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 complete the construction, calibration, and validation of an Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Minnesota portions of three watersheds: Root River, Upper Iowa, and Mississippi River-Reno.
The goal of this project is to test the sensitivity of the Zumbro River Watershed Hydrological Simulation Program FORTRAN (HSPF) model management scenario results. Additional goals are to develop Total Maximum Daily Loads (TMDLs) for impaired stream reaches and Rice Lake, which will be documented in a TMDL Report. The consultant will apply the existing calibrated and validated Zumbro River Watershed HSPF model to construct load duration curves to develop TMDLs.
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).
