Wisconsin Water Science Center


Since 1906, the Wisconsin Water Science Center has been collecting high-quality hydrologic data and conducting unbiased, scientifically sound research on Wisconsin's water resources. 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.

A new water-quality monitoring program, established by the U.S. Geological Survey, can provide scientists and managers with the best available data to help evaluate the health of Great Lakes ecosystems and improve water quality for recreation and commercial fishing.

Little Plover River Wells
April 6, 2017

Both irrigation wells and municipal wells affect flows in the Little Plover River near Plover, Wisconsin, stretches of which ran dry in past years, according to a new scientific report.

Depletion mapping and constrained optimization to support managing groundwater extraction

Groundwater models often serve as management tools to evaluate competing water uses including ecosystems, irrigated agriculture, industry, municipal supply, and others. Depletion potential mapping—showing the model-calculated potential impacts that wells have on stream baseflow—can form the basis for multiple potential management approaches in an...

An evaluation of the zooplankton community at the Sheboygan River Area of Concern and non-Area of Concern comparison sites in western Lake Michigan rivers and harbors in 2016

The Great Lakes Areas of Concern (AOCs) are considered to be the most severely degraded areas within the Great Lakes basin, as defined in the Great Lakes Water Quality Agreement and amendments. Among the 43 designated AOCs are four Lake Michigan AOCs in the State of Wisconsin. The smallest of these AOCs is the Sheboygan River AOC, which was...
