Beach Advisory - End of Season

Beaches Monitored from Memorial Day through Labor Day
From May to September, the Health Department's Lakes Management Unit samples Lake Michigan beaches 4 days a week. Beaches on inland lakes are tested biweekly. The water samples are tested for E coli bacteria, which are found in the intestines of almost all warm-blooded animals. While not all strains of E coli are the same, certain strains can make humans sick if ingested in high enough concentrations.

Closures
If water samples come back high for E coli (235 E coli/100 ml), the management body for the bathing beach is notified and a sign is posted indicating the beach closure. Additionally, since rain events tend to lead to elevated bacteria levels in the water column, the LMU advises that persons avoid swimming after a large rain event.

Note: Per the Illinois Swimming Code, there is no swimming at dog beaches.
