GERALDTON – Area residents are being advised of the confirmation of the presence of blue-green algae identified in a water sample taken at Kenogamisis Lake.
Residents are reminded that water should be avoided whenever a blue-green algae bloom is present, and for roughly two weeks after it has dissipated.
The water at Kenogamisis Lake should not be consumed or used for household purposes or swimming while blue-green algae is present, and pets should be kept away from the water, according to the Thunder Bay District Health Unit, 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 and are usually present in low numbers but can rapidly increase in warm, shallow, surface water that gets a lot of sun,” said the health unit in a release on Thursday.
“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 that pose a health risk to people and animals when consumed, inhaled, or even from skin contact and the Health Unit suggests that 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, the Helath Unit said that 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. For more information on blue-green algae blooms, please visit the Ministry of the Environment, Conservation and Parks website.
