Region 3: Great Lakes

Welcome to Region 3! Our Region includes the states of Minnesota, Wisconsin, Michigan, Illinois, Indiana, and Ohio. We conduct science to inform resource managers on issues such as aquatic invasive species, water quality and availability, wildlife disease, and restoration of fish/wildlife and their habitats.

USGS National Water Quality Monitoring Network

What is the U.S. Geological Survey National Water Quality Monitoring Network?Understanding the water quality of U.S. streams and rivers requires consistent data collection and analysis over decades. The U.S. Geological Survey’s (USGS) National Water Quality Network (NWQN) was established to facilitate national-scale understanding of surface-water quality conditions through the collection of compar

Geochemical data for Illinois Basin coal samples, 2015–2018

Researchers at the U.S. Geological Survey (USGS) and their collaborators conducted a study of the geochemical properties of coals currently produced for electric power generation in the Illinois Basin in Illinois and Indiana. The study follows from recommendations by an expert panel for the USGS to investigate the distribution and controls of trace constituents such as mercury (Hg) in Illinois Bas

Phylogeographic genetic diversity in the white sucker hepatitis B Virus across the Great Lakes Region and Alberta, Canada

Hepatitis B viruses belong to a family of circular, double-stranded DNA viruses that infect a range of organisms, with host responses that vary from mild infection to chronic infection and cancer. The white sucker hepatitis B virus (WSHBV) was first described in the white sucker (Catostomus commersonii), a freshwater teleost, and belongs to the genus Parahepadnavirus. At present, the host range of

Invasive Phragmites Science: Management Tools for the Control of Invasive Phragmites to Foster the Restoration of the Great Lakes

The USGS is developing innovative Phragmites control measures to keep this rapidly spreading invasive plant from further expanding its range into new wetland habitats and to aid in the development of successful restoration strategies. Scientists are conducting studies and field tests to determine if fungi that live within the Phragmites are enabling the plant to take over habitat used by native...
