August 30, 2022 - The Ministry of the Environment, Conservation and Parks has confirmed the presence of blue-green algae in a water sample collected at East Loon Lake on August 22 and 23, 2022. It is important to remember that water should be avoided whenever a blue-green algae bloom is present, and for about 2 weeks after it has dissipated.
When blue-green algae is present in water, it is important to avoid drinking the water, using it for household purposes, or swimming in it. Keep pets away from the water as well, as their smaller size and propensity for drinking lake water makes them more vulnerable.
Blue-green algae are microscopic organisms that are naturally present in lakes and streams. They are usually present in low numbers but can rapidly increase in warm, shallow, surface water that gets a lot of sun. When this happens, they can form blooms that make the water look like green pea soup or turquoise paint. When the bloom is very large, the harmful algae bloom may form scum or solid-looking clumps on the water surface. Some blue-green algae blooms produce toxins than pose a health risk to people and animals when consumed, inhaled, or even from skin contact. If contact with a blue-green algae bloom does occur, wash with soap and water and rinse with clean water to remove the algae.
Blue-green algae blooms in lakes in our region have been relatively uncommon, historically. However, with rising climate and water temperatures they may become more common.
If you spot a suspected blue-green algae bloom, report it to the Spills Action Centre at 1-800-268-6060.
