Upper Midwest Water Science Center
Home
Our USGS Upper Midwest Water Science Center priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices. If you need additional assistance, please contact Center Director John Walker at jfwalker@usgs.gov.

Water Resources in Minnesota Significantly Improved by Land Restoration
Conversion of agricultural lands to wetland and native prairie greatly enhanced the quality of water resources, increased groundwater recharge and decreased floodwaters in the Glacial Ridge National Wildlife Refuge, Minnesota, according to a U.S. Geological Survey study.
Surface-Air Mercury Fluxes and a Watershed Mass Balance in Forested and Harvested Catchments
Forest soils can act as repositories for atmospherically deposited mercury, yet forestry practices can influence mercury mobility and fluxes, food web dynamics, and bioaccumulation processes.
USGS Unveils Mobile Flood Tool for the Nation
The U.S. Geological Survey announced Friday the completion of a new mobile tool that provides real-time information on water levels, weather and flood forecasts all in one place on a computer, smartphone or other mobile device.

Evidence for interannual persistence of infectious influenza A viruses in Alaska wetlands
Influenza A viruses (IAVs) deposited by wild birds into the environment may lead to sporadic mortality events and economically costly outbreaks among domestic birds. There is a paucity of information, however, regarding the persistence of infectious IAVs within the environment following deposition. In this investigation, we assessed the...

Instruments, methods, rationale, and derived data used to quantify and compare the trapping efficiencies of four types of pressure-difference bedload samplers
Bedload and ancillary data were collected to calculate and compare the bedload trapping efficiencies of four types of pressure-difference bedload samplers as part of episodic, sediment-recirculating flume experiments at the St. Anthony Falls Laboratory, University of Minnesota, Minneapolis, in January–March 2006. The bedload-sampler experiments,...
Gray, John R.; Schwarz, Gregory E.; Dean, David J.; Czuba, Jonathan A. ; Groten, Joel T. Earlier winter/spring runoff and snowmelt during warmer winters lead to lower summer chlorophyll-a in north temperate lakes
Winter conditions, such as ice cover and snow accumulation, are changing rapidly at northern latitudes and can have important implications for lake processes. For example, snowmelt in the watershed—a defining feature of lake hydrology because it delivers a large portion of annual nutrient inputs—is becoming earlier. Consequently, earlier and a...
