Algae Reappears in Willis Lake
Officials are warning folks (and animals) to stay away from the water at Willis.

Officials inspected the water at Willis Lake and found the presence of algae, again.
The green algae, or, more specifically cyanobacteria, was confirmed earlier this summer. Prolonged warm temperatures may be contributing to the blooms, said a release.
The Department of Public Health has been notified and an advisory posted at the lake.

People and pets should avoid contact with the water at Willis Lake until further notice, said the announcement. Ingesting small amounts of toxin (microcystin), produced by cyanobacteria, can cause gastrointestinal distress. Symptoms of microcystin poisoning are abdominal pain, diarrhea, and vomiting. Elevated levels of the toxin may cause serious neurological effects. Eye, ear, and skin irritations can also occur. Contact your physician if you experience symptoms.
