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.
The goal of this project is to develop and complete the Watershed Restoration and Protection (WRAP) process and report, while also enlarging and sustaining a public participation process that encourages local ownership of water quality problems and solutions (civic engagement).
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 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.
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.
