Take Note

Blue-green algae advisory issued for Pine Lake

Jul 30, 2025 | 10:43 AM

Cyanobacteria (blue-green algae) has been identified in the waters of Pine Lake, located approximately 40 kms southeast of Red Deer.

Visitors to the lake are advised to take the following precautions:

• Avoid all contact with cyanobacterial 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 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).

As always, officials with Alberta Health Services (AHS) say visitors and residents are reminded to never drink or cook with untreated water directly from any recreational body of water, including Pine Lake, at any time. The health agency says boiling of this water will not remove the toxins produced by cyanobacteria. An alternate source of drinking water should also be provided for pets and livestock while this advisory is active, officials point out.

AHS says Cyanobacteria 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, officials note cyanobacteria can be blue-green, greenish-brown, brown and/or pinkish-red, and often smell musty or grassy.

According to AHS, people who come in contact with visible cyanobacteria or who ingest water containing cyanobacteria may experience skin irritation, rash, sore throat, sore red eyes, swollen lips, fever, nausea and vomiting and/or diarrhea. Officials say symptoms usually appear within one to three hours and resolve in one to two days. Symptoms in children are often said to be more pronounced; however, all humans are at risk of these symptoms. AHS says exposure to the bacteria may be fatal to pets.

Officials say 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 Pine Lake until further notice.

Please note the waters of Pine Lake in which the cyanobacterial bloom is NOT visible can still be used for recreational purposes, even while this Health Advisory is in place.
