Cyanobacteria advisories lifted across Alberta

Nov 3, 2026 | 2:18 PM

Cyanobacteria (blue-green algae) advisories have been lifted across Alberta, according to Alberta Health Services.

Recent weather has cooled lake and reservoir water temperatures to such an extent that cyanobacteria and water quality, including fecal bacteria levels, present a low health risk for usage of the lake for recreational purposes, officials say.

Effective immediately, Alberta Health Services has lifted the cyanobacterial bloom advisories for:

  • Astotin Lake
  • Beaver Lake
  • Blood Indian Creek Reservoir
  • Bonnie Lake
  • Buffalo Lake (North)
  • Chump Lake
  • Driedmeat Lake
  • Eagle Lake
  • Floatingstone Lake
  • Goose Lake
  • Half Moon Lake
  • Hope Lake
  • Iosegun Lake
  • Isle Lake
  • Lac Cardinal
  • Lac La Biche
  • Lac La Nonne
  • Lac Ste. Anne
  • Lake Sundance
  • Lessard Lake
  • Long Lake (Thorhild County)
  • Matchayaw (Devil’s) Lake
  • Milk River Ridge Reservoir
  • Moonshine Lake
  • Moose Lake
  • Nakamun Lake
  • Paddle River Reservoir
  • Pigeon Lake
  • Pine Lake

  • Severn Creek Reservoir
  • Shorncliffe Lake
  • Skeleton Lake
  • Steele (Cross) Lake
  • Stoney Lake
  • Thunder Lake

Effective immediately, AHS has lifted the water quality advisories for:

  • Half Moon Lake Resort
  • Golden Sands Beach
  • MacFarlane Beach

  • Plamondon White Sands Beach
  • Ridge Park Beach
  • Shorncliffe Lake Park
  • Sir Winston Churchill Provincial Park – Campers Beach
  • Stoney Lake Municipal Campground Beach
  • Sunset Point Christian Foundation

Visitors and residents are reminded to never drink or cook with untreated water directly from any lake or reservoir at any time, AHS adds.

Boiling water won’t remove toxins produced by cyanobacteria. An alternate source of drinking water should also be provided for pets and livestock when cyanobacteria may be of concern.
