Des Plaines Park District

BLUE-GREEN ALGAE

LAKE OPEKA IS TEMPORARILY CLOSED

PLEASE STAY AWAY FROM THE WATER!

For the safety of our patrons and pets, Lake Opeka is closed due to a blue-green algae bloom.
Environmental testing performed by both the EPA and a private firm has determined hazardous levels of toxicity, particularly in the marina.
DO NOT FISH ANYWHERE IN THE LAKE UNTIL FUTURE TEST RESULTS SHOW THE WATER IS SAFE.

Blue-Green Algae Toxicity is not airborne. Walking the lakefront path and enjoying activities in Lake Park is safe for everyone.


The lake is closed to all activity until further notice.

What can be done?
The advice from environmental experts is to let the bloom run its course.
Treating it with chemicals can harm the lake and lead to a more severe bloom.
