Upper Midwest Water Science Center

Home

The Upper Midwest Water Science Center collects high-quality hydrologic data and conducts unbiased, scientifically sound research on water resources in Michigan, Minnesota, and Wisconsin. We strive to meet the changing needs of those who use our information—from the distribution, availability, and quality of our water resources to topic-oriented research that addresses current hydrological issues.

USGS Flood Experts Respond to High Water in Central, Northeastern U.S.

Crews from the U.S. Geological Survey have been in the field for weeks measuring flooding in the Midwest and in the Mississippi River watershed, and more recently flooding and storm tides on the Northern Atlantic coast, as higher temperatures, heavy rain, snowmelt and nor’easters affected numerous states.

Estimates of long-term mean daily streamflow and annual nutrient and suspended-sediment loads considered for use in regional SPARROW models of the Conterminous United States, 2012 base year

Streamflow, nutrient, and sediment concentration data needed to estimate long-term mean daily streamflow and annual constituent loads were compiled from Federal, State, Tribal, and regional agencies, universities, and nongovernmental organizations. The streamflow and loads are used to develop Spatially Referenced Regressions on Watershed...

Chemical and physical controls on mercury source signatures in stream fish from the northeastern United States

Streams in the northeastern U.S. receive mercury (Hg) in varying proportions from atmospheric deposition and legacy point sources, making it difficult to attribute shifts in fish concentrations directly back to changes in Hg source management. Mercury stable isotope tracers were utilized to relate sources of Hg to co-located fish and bed sediments...

Effects of manure and tillage on edge-of-field phosphorus loss in seasonally frozen landscapes

Environmental conditions and management practices affect nutrient losses in surface runoff, but their relative impacts on phosphorus (P) loss during frozen and nonfrozen ground periods have not been well quantified. More specifically, the relative importance of manure application, tillage, and soil-test P (STP) has not been assessed at the field...
