A cooperative study was conducted by the U.S. Geological Survey (USGS), the Metropolitan Council, and the Minnesota Department of Health to assess groundwater and surface-water interactions in lakes in the northeast Twin Cities Metropolitan Area (TCMA), including White Bear Lake. An important product of the study was the creation of a groundwater-flow model focused on the northeast TCMA. The groundwater flow model is available for future use to assess the effects of groundwater withdrawals on lake levels as well as to describe other groundwater and surface-water interactions.
Our program will protect, in perpetuity, native prairie tracts in western Minnesota. Fee title tracts will be the top priority for the funding. Funding will be used for the purchase of habitat easements if the funding cannot be used entirely on fee title tracts. The funding will purchase approximately 525 acres of native prairie in fee title, 1,583 acres of habitat easements, or a combination of the two.
The study will assess existing phosphorus data records and create a model to explain phosphorus loading into the Red River of the North. Studies have found that the majority of nutrient loading in the stream located in agricultural areas occurs with sediment loading since nutrients are typically bound to sediment particles.
This project will collect real-time parameter data for specific conductance, water temperature, pH, dissolved oxygen, turbidity and stream flow at the United States geological Survey (USGS) gaging stations located at Fargo, ND and Grand Forks, ND on the Red River of the North; and publish the data both on the USGS NWIS website and in the USGS Annual Report.
The Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
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.
