Update as of Sept. 11, 2023
WARNING - The public should avoid contact with the water in Lake Cornelia. The water contains blue-green algae at levels that may cause short-term and long-term harm including skin irritation, gastrointestinal problems, and/or liver damage. People and pets should avoid all contact with the water, scum, or algae.
Analyses of recent water samples that the Nine Mile Creek Watershed District took from Lake Cornelia indicate blue-green algae numbers that exceed the World Health Organization (WHO) threshold for a moderate probability of adverse health risks in both basins. The District will be collecting another sample from both North and South Cornelia and will release updated information on algal levels when it is available following the sample event.
