Alberta Health Services has lifted warnings about toxic blue-green algae for Clear Lake, Pine Coulee Reservoir, Twin Valley Reservoir, Severn Creek Reservoir and Eagle lake.
In a Wednesday statement, health officials said recent weather has “cooled lake and reservoir water temperatures to such an extent that blue-green algae is no longer a health concern.”
Exposure to or ingestion of blue-green algae can cause rash, sore eyes or throat, swollen lips, fever, nausea and vomiting or diarrhea.
Children are often more severely affected. Symptoms usually resolve in a day or two.
The algae, also known as cyanobacteria, occurs naturally.
It can look like scum, grass clippings, fuzz or globs on the surface of water.
It can be blue-green, greenish-brown, brown, and/or pinkish-red, and often smells musty or grassy.
Advisories remain in place for several other lakes. You can find more information here.
