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.
