CALGARY – A blue-green algae (cyanobacteria) bloom has been identified in Travers Reservoir. Residents living near the shores of this reservoir, as well as visitors to this reservoir, are advised to take the following precautions:
As always, visitors and residents are reminded to never drink or cook with untreated water directly from any recreational body of water, including Travers Reservoir, at any time. Boiling of this 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 reservoir to another. As such, this advisory will remain in effect for Travers Reservoir, until further notice.
Please Note: areas of Travers Reservoir 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.
If you suspect a problem related to blue-green algae (cyanobacteria), or if you require further information on health concerns and blue-green algae (cyanobacteria), please call Health Link at 811. Additional information is also available online, at .
