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

Assessing the health risk from waterborne pathogens for public users recreating on future Iowa Water Trails recreation sites near Des Moines

Scientists at LIDE are collaborating with Polk County Conservation in central Iowa to estimate the health risk posed to recreators in the Des Moines River and tributaries. Samples collected over two years are tested for viral, bacterial, and protozoan pathogens, and health risk is estimated using quantitative microbial risk assessment (QMRA). Health risk will also be compared to microbial source...

Well Water Advisory Forecasts for northeast Wisconsin

The fractured bedrock of northeast Wisconsin is vulnerable to groundwater contamination because water and contaminants can move quickly. LIDE is launching a study to predict contamination of private wells in northeast WI using Runoff Risk Advisory Forecasts (RRAF). RRAF is an online tool that forecasts conditions conducive to surface runoff, and the long-term vision is to leverage its forecasts to...

MMSD Watercourse Corridor Study: Nutrient Evaluations

Eutrophication and harmful algal blooms (HABs) are becoming an increasing concern in the Great Lakes. Although there is a total maximum daily load (TMDL) for phosphorus in the Milwaukee Estuary, abundance/biovolume of potential HAB-producing cyanobacteria and cyanotoxin presence in Milwaukee-area rivers and the estuary are largely unknown. USGS evaluations of nutrients in the MMSD Watercourse...
