The Leeds, Grenville and Lanark District Health Unit is warning residents to watch for algal blooms as autumn arrives. Cooler surface water brings nutrients from lake bottoms, potentially causing late algae blooms.
While many blooms are harmless, some can produce toxins dangerous to people and animals. The Health Unit advises caution when near a suspected harmful bloom, as toxins can cause skin irritation, nausea, and even liver issues.
Residents using surface water for drinking should be cautious, as typical treatments like boiling or chlorination do not remove toxins. The Health Unit recommends consulting a specialist or finding alternative water sources.
Swimming and water sports should be avoided in affected areas. Residents are also advised not to eat the organs of fish caught in water with algae blooms.
To report new algal blooms, contact the Spills Action Center. For more information, visit the Health Unit’s Recreational Water page.
