Upper Midwest Water Science Center
Welcome to the Upper Midwest Water Science Center’s (UMid) Website. We offer information on streamflow, water quality, water-use, and groundwater data for Minnesota, Wisconsin and Michigan. We conduct unbiased, scientific hydrologic investigations and research projects to effectively manage the Upper Midwest's and our Nation's water resources through joint efforts with our partners.

U.S. Geological Survey science strategy to address highly pathogenic avian influenza and its effects on wildlife health 2025–29 U.S. Geological Survey science strategy to address highly pathogenic avian influenza and its effects on wildlife health 2025–29
Executive SummaryHighly pathogenic avian influenza (HPAI) is an ecologically and economically important animal disease that can also directly affect humans (a “zoonotic” disease). HPAI was once limited almost exclusively to domestic poultry but has rapidly adapted to diverse animal hosts. Viruses causing HPAI now appear to be maintained and dispersed by wild birds largely independent of...
Evaluating per- and polyfluoroalkyl substance (PFAS) prevalence and potential for biological effects in Lake Superior tributaries Evaluating per- and polyfluoroalkyl substance (PFAS) prevalence and potential for biological effects in Lake Superior tributaries
Several per- and polyfluoroalkyl substances (PFAS) are Great Lakes binational chemicals of mutual concern. Although known to be persistent, data gaps regarding PFAS prevalence and biological effects exist, especially within Lake Superior’s watershed. In this 2022 study of 27 United States tributaries to Lake Superior, water samples were collected during spring runoff, summer baseflow...
One-hundred fundamental, open questions to integrate methodological approaches in lake ice research One-hundred fundamental, open questions to integrate methodological approaches in lake ice research
The rate of technological innovation within aquatic sciences outpaces the collective ability of individual scientists within the field to make appropriate use of those technologies. The process of in situ lake sampling remains the primary choice to comprehensively understand an aquatic ecosystem at local scales; however, the impact of climate change on lakes necessitates the rapid...

Beyond the Usual Suspects: A Comprehensive Look at Agricultural Stream Contaminants
Clean water is essential for both environmental health and human safety, but many everyday products and activities can contribute to water pollution including contaminants such as microplastics, harmful chemicals such as pharmaceuticals and pesticides, and antibiotic resistance genes. A recent USGS study in Iowa investigated pollutants in streams, including stream sediment and biota, to determine...
Wings of Change: The Environment's Influence on Bird Flu
Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."
