There won't be any swimmers, but people who walk pets near some southern Alberta water bodies will be happy.

Cooler lake and reservoir water temperatures mean there's no longer a concern for blue green algae.

Clear Lake, Pine Coulee Reservoir and Twin Valley Reservoir in the Calgary AHS Zone, had all previously been placed under blue-green algae or cyanobacteria bloom advisories.

Alberta Health Services has lifted the advisories effective immediately.
