Below is the Pigeon Lake Blue-green advisory issued.
Remember that Pigeon Lake is a big lake. Note the paragraph that states "areas of Pigeon Lake in which the blue-green algae (cyanobacteria) bloom is not visible can still be used for recreational purposes".
Most of the time it is a matter of common sense. Most PLWA directors still enjoy water activities after an advisory is issued though as per the advisory, do not swim when blue-green algae is visible. As per the advisory we take precautions: When it is not visible we enjoy the lake taking care not to swallow the lake water; we wash off after being in the lake and add practices such as keeping pets indoors or tied up with alternate water sources.
Keep informed, follow the precautionary practices and have a great summer. Over time, all of our efforts will help the water quality.
Advisory issued for Pigeon Lake
August 5, 2016: A blue-green algae (cyanobacteria) bloom has been identified in areas of Pigeon Lake. Residents living near the shores of this lake, as well as visitors to this lake, are advised to take the following precautions:
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).
As always, visitors and residents are reminded to never drink or cook with untreated water directly from any lake, including Pigeon Lake, at any time. Boiling lake water will not remove the toxins produced by blue-green algae (cyanobacteria). An alternate source of drinking water should also be provided for pets and livestock, while this advisory is active.
Blue-green algae (cyanobacteria) is naturally occurring, and often become visible when weather conditions are calm. Appearing like scum, grass clippings, fuzz or globs on the surface of water, blue-green algae (cyanobacteria) can be blue-green, greenish-brown, brown, and/or pinkish-red, and often smell musty or grassy.
People who come in contact with visible blue-green algae (cyanobacteria), or who ingest water containing blue-green algae (cyanobacteria), 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 Pigeon Lake, until further notice.
Please note that areas of Pigeon Lake in which the blue-green algae (cyanobacteria) bloom is NOT visible can still be used for recreational purposes, even while this Blue-green Algae (Cyanobacteria) Advisory is in place.
