Take precautions

Blue-green algae advisory issued for Reesor Lake

Jul 16, 2021 | 4:24 PM

Alberta Health Services advises people living near the shores of Reesor Lake and visitors to take precautions after a blue-green algae (cyanobacteria) bloom has been identified at the lake.

• Avoid all contact with blue-green algae (cyanobacteria) blooms. If contact occurs, wash with tap water as soon as possible.
• Do not swim or wade (or allow your pets to swim or wade) in any areas where blue-green algae (cyanobacteria) is visible.
• Do not feed whole fish or fish trimmings from this lake to your pets.
• Consider limiting human consumption of whole fish and fish trimmings from this lake, as it is known that fish may store toxins in their liver. (People can safely consume fish fillets from this lake).

AHS reminds visitors and residents to never drink or cook with untreated water directly from any recreational body of water at any time. Boiling of this water will not remove the toxins produced by blue-green algae. An alternate source of drinking water should also be provided for pets and livestock, while this advisory is active.

“Blue-green algae is naturally occurring, and often becomes visible when weather conditions are calm. Appearing like scum, grass clippings, fuzz or globs on the surface of water, blue-green algae can be blue-green, greenish-brown, brown, and/or pinkish-red, and often smell musty or grassy,” reads a release from AHS.

People who come in contact with visible blue-green algae or who ingest water containing blue-green algae may experience skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea and vomiting and/or diarrhea. Symptoms usually appear within one to three hours and resolve in one to two days. Symptoms in children are often more pronounced; however, all humans are at risk of these symptoms.

Weather and wind conditions can cause algae blooms to move from one location in the lake to another. As such, this advisory will remain in effect for Acadia Valley Reservoir, until further notice. Please note that areas of Reesor Lake in which the blue-green algae bloom is not visible can still be used for recreational purposes, even while this blue-green algae Health Advisory is in place.
