Manteno, IL – A contamination advisory has been issued for the beach at Manteno Sportsmen’s Club after recent water samples revealed elevated bacteria levels.
According to the Illinois Department of Public Health, a June 19 sampling showed a shallow water reading of 2,419.6 colony-forming units (cfu) per 100 milliliters — significantly above the state’s acceptable threshold for safe swimming. The advisory, which began Friday, has prompted a temporary warning against full-body contact with the water at the Kankakee County facility.
A Facebook post by the Manteno Sportsmen’s Club on Sunday stated they were “not officially notified” by the state before learning of the advisory through a member. The club clarified that while they are not under an official closure, they are treating the situation seriously and plan to re-test the water as soon as possible.
“We plan on contacting the state tomorrow morning to get a new sample kit sent ASAP,” the club wrote in the post. “As always, use your own discretion when deciding to swim at the beach or not.”
The club’s beach, which is privately owned and accessible only to members, has been monitored twice monthly during the swim season by the Illinois Department of Public Health for years. A similar advisory was last issued for the site in 2014.
The current advisory is expected to remain in place for up to 10 days, pending retesting and confirmation of safer conditions. Swimmers are advised to use personal discretion before entering the water.
