It took over the water last summer. This year, not so much.
Blue-green algae is more of a rare sight for those looking for water getaways in Alberta.
Around this time last year, over 15 lakes and ponds were reportedly infected. Currently, only six lakes have blue-green algae advisories (Moose Lake, Murray Lake, Alix Lake, Stoney Lake, Vincent Lake and Isle Lake).
"It's unpredictable. When you compare it's statistically less," said Shobhit Maruti, medical officer of health at Alberta Health Services. "It could be in the next month we could get more or none at all, so waiting till the season is done to officially say if we'll see more or less."
Astotin Lake at Elk Island National Park is one of the cyanobacteria-free bodies of water in the area.
"This is the time for it to form because it's warm outside," added Maruti. "The best time to compare year to year totals is in the mid-fall."
