Beach Advisory 

(End of Season, Check Back in May 2014)

Beaches are 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 bi-weekly. 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.   
 
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. 

Nunn Beach at the Great Lakes Naval Station will be closed for the 2013 season.

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

Elevated Bacteria  Levels, Caution Swimming Advisory
