The Allegan County Health Department is advising all residents not to swim in Dumont Lake because of problems with E. coli.

Test results from Tuesday, Aug. 8, showed high levels of E. Coli, prompting the department to warn residents against swimming/body contact with the water at this time.

In a post on Facebook, the department said, “Swim at your own risk. If swimming, consider practicing safe swimming and help prevent recreational water illnesses.

• Keep pets off the beach.

• Do not feed the birds.

• Use the restroom before swimming.

• Do not swim in water that smells foul, looks murky, or immediately after a heavy rain.

• Do not swallow lake water.

• Vigorously towel off after swimming.

• Wash your hands with soap and water before eating.

• Shower as soon as possible when you return home.
