An anticipated increased incidence of climate-related extreme rainfall events in the Great Lakes region may raise the public health risk for the 40 million people who depend on the lakes for their drinking water, according to a new study.

Long a problem in the western U.S., the New Zealand mud snail currently inhabits four of the five Great Lakes and is spreading into rivers and tributaries, according to a Penn State team of researchers.

A Michigan Technological University professor has developed a new water treatment that could help keep a deadly fish disease out of Lake Superior.

Throughout the overlooked depths of Lake Michigan and other Great Lakes, a small but important animal is rapidly disappearing.

A group of specialists will investigate why a federal agency is withholding a report describing potential health threats near 26 heavily polluted areas in the Great Lakes region.

Researchers in Michigan report new evidence that water levels in the Great Lakes, which are near record low levels, may be shrinking due to global warming. Their study, which examines water level data for Lakes Michigan and Huron over more than a century, is scheduled for the Dec. 15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal.

U.S. Environmental Protection Agency and Environment Canada today released the 2007 State of the Great Lakes Highlights Report at the International Joint Commission meeting in Chicago.

A lethal fish virus in the Great Lakes and neighboring waterways is approaching epidemic proportions, according to Paul Bowser, Cornell professor of aquatic animal medicine in the College of Veterinary Medicine. The viral hemorrhagic septicemia virus (VHSV), which causes anemia and hemorrhaging in fish, has now been identified in 19 species and poses a potential threat to New York's $1.2 billion sport-fishing industry.

Help STOP the Spread of Viral Hemorrhagic Septicemia virus (VHSv). A deadly new fish virus that caused huge fish kills in several eastern Great Lakes in 2005 and 2006 is likely already in Lake Michigan and may be in Lake Superior and the Mississippi River. We need your help to ensure this virus doesn't spread to inland lakes and rivers, where it could potentially devastate fish populations and ruin our fishing.
