The Great Lakes represent approximately 20 percent of the world’s fresh surface water and provide habitat for over 100 species of globally rare plants and animals. Additionally, 42 million people depend on the Great Lakes for their drinking water. In recent years, the lakes have been impacted due to invasive species, contaminants, land use decisions, and more. IISG has joined with agencies, universities, and organizations to monitor, improve, and protect this valuable resource.



Great Lakes Monitoring
Great Lakes Monitoring is a web application that makes it easy to view and analyze decades of nutrient, contaminant, and water characteristic data collected by universities and government agencies, including the U.S. EPA Great Lakes National Program Office.

Lake Michigan Nearshore Buoy
Real-time buoys that broadcast water conditions help scientists, managers, and residents understand how the lake works, how things look today, or how things will look in the future. The IISG buoy in nearshore waters of Michigan City, IN is proving to be a valuable resource.

GLRRIN Lake Michigan
The Great Lakes Regional Research Information Network is a binational, collaborative effort among federal and state agencies, academic institutions, and the private sector involved in Great Lakes research.

The Cooperative Science and Monitoring Initiative (CSMI) is a binational project that brings together federal, regional, and local partners to study Great Lakes food webs and pinpoint the impacts of stressors. CSMI is focused on a different lake each year—2015 is Lake Michigan.
