The primary goal of this project is to analyze of dated sediment cores to reconstruct changes in the lake condition over the last 150 years. This will be done using multiple lines of evidence including biogeochemistry, sediment accumulation, and diatom and algal remains as biological indicators.
This project will update sediment Total Maximum Daily Loads (TMDLs) for 60-64 impaired stream reaches and provide a final TMDL report. The report will address sediment and turbidity impaired streams in the Minnesota River Watershed. TMDLs will describe the impairment in each water body and water quality targets, and will include a discussion of pollutant sources, supporting report components that document assumptions and methodologies, and TMDL equations with completed load allocations, wasteload allocations, and margin of safety for each impairment.
This project addresses five reaches of the Minnesota River that have aquatic recreation impairments as identified by high concentrations of E. coli. The project will describe the water quality impairments, complete pollutant source assessments, establish loading capacities and allocations for the impairments, and develop implementation strategies.
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 impairments and maintain or improve water quality 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 lakes, allocate pollution reduction goals, and prioritize and identify implementation strategies to maintain or improve water quality in key lakes and streams in the watershed.
This is a joint project between the United States Geological Survey (USGS), Minnesota Pollution Control Agency (MPCA), North Dakota, and Manitoba. The project is a basin-wide, up-to-date water quality trend analysis using the "QWTrend" program for approximately 40 bi-national river sites to review nutrients, total suspended solids, total dissolved solids, sulfate and chloride from 1980 - 2015.
