The goal of this project is to collect data, water chemistry and field parameters, which will be paired with biological data collected by the MPCA to assess water quality conditions at seven sites along targeted reaches within the Snake River Watershed and five sites in the Two River Watershed.
This project will be a complete TMDL report for the Biota and Bacteria (E. coli) impairments for the Ann River Watershed. The water bodies associated with these impairments will then be removed from the MPCA’s impaired waters list, and implementation activities to restore the water bodies will begin.
This project will complete a TMDL equation and report and an implementation plan for Deer Creek. The TMDL report will describe turbidity impacts to aquatic life uses of Deer Creek, correlate turbidity to other pollutants (sediment, suspended solids, etc.), describe and quantify unique turbidity/sediment stressors which include groundwater influences, legacy impacts of the watershed and stream channel, significant in-stream and near stream sources (slumps, bank erosion, etc.) and upland contributions.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This project will maximize the utility and usefulness of three HSPF models that have been constructed and calibrated for hydrology. The contractor will identify and reduce parameterization errors in the following three HSPF models: 1) Buffalo River Watershed, 2 ) Thief River Watershed, 3) Bois de Sioux-Mustinka Watersheds. This will result, not only in a better hydrology calibration, but will also improve each of the models’ ability to more accurately estimate sediment and pollutant loads and concentrations.
The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
The goal of this project is to supplement and refine the Deer Creek Watershed TMDL Report and Implementation Plan project with detailed determinations of critical source areas and prioritization of the associated management practices, facilitated by additional meetings with local resource managers and validated with a field survey. Completed work will more fully inform the TMDL report and TMDL implementation plan on critical source areas of sediment and quantify those sources.
The St. Louis River Area of Concern (SLRAOC) conservation partners are focused on removing Beneficial Use Impairments (BUI) in the estuary and eventually delisting the SLRAOC. Cooperative efforts between multiple resource agencies and regional stakeholders have identified a host of restoration objectives, developed project support activities, and partially secured funding that includes a state commitment through the Minnesota Clean Water Fund.

This project will define the major factors causing harm to fish and other river and stream life within the Nemadji watershed. Stressor identification is a formal and rigorous process to identify these factors, explain the linkages between the results of biological monitoring and water quality assessments, and organize this information into a structure of scientific evidence that supports the conclusions of the process. Stressor identification is a component of the Watershed Restoration and protection (WRAP) approach.
This project will complete a Total Maximum Daily Load (TMDL) study for the impaired reaches of the Snake River Basin. The project includes development of a Generalized Watershed Loading Function (GWLF) model for nutrient sources and Total Suspended Sediment (TSS), a spreadsheet version of a BATHTUB model of lake response for four lakes, and a bacteria source assessment. Wenck will also provide all stream channel data as a spreadsheet and locational database.
