Beach Advisory - End of the Season (check back in May 2020) 

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 (2 times per month). 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.
