PIGEON LAKE FISHERMAN-FRIENDLY AGAIN
The blue-green algae advisory for Pigeon Lake has been lifted by Alberta Health Services after careful monitoring of the water indicated that it is safe to swim, wade and consume fish from the lake. Signage warning of blue-green algae in Pigeon Lake will be removed.
Blue-green algae, or cyanobacteria, are microscopic organisms that are naturally present in our lakes and streams, usually in low numbers, yet blue-green algae can increase significantly in warm, shallow and undisturbed surface water during a period of hot weather and lots of sunshine. As a shallow-dished lake, Pigeon has been susceptible to blue-green algae for several years.The threat to health from skin contact with algae-infested waters are the toxins produced by the cyanobacteria. Some algae produced toxins known to effect the liver, others, the nervous system, and still others are neurotoxins. Toxins affecting the liver are the most common in prairie waters. Algae bloom toxins are also known to cause eye and throat irritation, skin inflammation, abdominal pain and vomiting, fever and diarrhea. Lake residents and visitors were warned to keep people, pets, and livestock away from the water when the blue-green algae was present.
