Blue-green algae (cyanobacteria) bloom, water quality advisories lifted in Central Zone

November 1, 2021

RED DEER – Recent weather has cooled lake and reservoir water temperatures to such an extent that blue-green algae is no longer a health concern, including in eight of water bodies in Central Zone, which had previously been placed under blue-green algae (cyanobacteria) bloom advisories.

Effective immediately, Alberta Health Services has lifted the blue-green algae (cyanobacteria) bloom advisories for:

Alix Lake
Astotin Lake
Bigelow Reservoir
Buck Lake
Haunted Lake
Little Beaver Lake
Wapasu Lake
Windsor Lake


AHS has also lifted the water quality advisory for:

Ebeling Beach at Aspen Beach Provincial Park on Gull Lake

As always, visitors and residents are reminded to never drink or cook with untreated water directly from any recreational body of water, at any time.
