Lake Michigan Beach Monitoring and Notification Program

Indiana's beaches are a wonderful place to play, watch wildlife, fish, and swim. Lake Michigan is an important resource to many people. Human activity impacts beach water quality. Polluted waters may contain disease-causing pathogens such as Escherichia coli (E. coli) bacteria. Contaminated beach water has the potential to make swimmers sick and closures due to water quality issues can have a negative impact on Indiana’s economy.

The U.S. Congress enacted the BEACH Act to protect public health at our nation’s coastal beaches. To safeguard beachgoers, the Indiana Department of Environmental Management (IDEM) and local organizations established the Lake Michigan Beach Monitoring and Notification Program with BEACH Act funding. IDEM partners with beach managers who monitor Lake Michigan beaches for E. coli and notify the public when beaches are closed or under advisory due to water contamination.

Hoosiers can help prevent pollution and protect Lake Michigan's ecosystem so present and future generations can enjoy Indiana’s unique coastline environment.
