Upper Midwest Water Science Center

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.

Current conditions in MI, MN, and WI

Explore real-time streamflow, groundwater, and water-quality conditions and access data with our interactive map application.

Geomorphic habitat response units for urban stream rehabilitation, Milwaukee, Wisconsin Geomorphic habitat response units for urban stream rehabilitation, Milwaukee, Wisconsin

Urban stream rehabilitation plans can benefit from knowledge of the landscape setting and vegetative communities that were adjacent to streams prior to urbanization. Downstream to upstream connections of these characteristics can be relevant for native migratory fish species that have a range of preferred spawning habitats. Based on a need for more quantitative data on these potential...

An inset groundwater-flow model to evaluate the effects of layering configuration on model calibration and assess managed aquifer recharge near Shellmound, Mississippi An inset groundwater-flow model to evaluate the effects of layering configuration on model calibration and assess managed aquifer recharge near Shellmound, Mississippi

The U.S. Geological Survey has developed a high-resolution inset groundwater-flow model in the Mississippi Delta as part of an interdisciplinary collaboration coordinated by the Mississippi Alluvial Plain project to provide a tool that stakeholders can use to support water-resource management decisions. Groundwater withdrawals from the Mississippi River Valley alluvial (MRVA) aquifer...

Quantifying depuration of methylmercury from fish consumption by travelers Quantifying depuration of methylmercury from fish consumption by travelers

During a two-week field sampling expedition in Gabon, two American scientists consumed fish daily from the Ogooué River watershed. We sampled their scalp and facial hair periodically to evaluate hair as a biomarker to track shifts in methylmercury (MeHg) exposure from diet. Each individual differed in the onset and extent of MeHg accumulation but showed similar depuration rates. Pretrip...

From Stream to Spider: How PFAS Move Through Aquatic and Terrestrial Food Webs

Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals that accumulate in the environment and living organisms. A USGS study examined how different PFAS compounds move through a stream ecosystem and are transferred from aquatic to terrestrial food webs. The findings documented that not all PFAS behave the same once they enter the environment, leading to differences in...

Bad River Watershed Assessments

The Bad River has one of the highest sediment loads of all Lake Superior tributaries and is an important resource for lake sturgeon and the Bad River Tribe. This study monitors the effects of streamflow variability on sediment-related problems, including understanding the influence of land cover on hydrology, habitat, erosion and sedimentation rates, and water quality of the Bad River.
