Blue-green algae (Cyanobacteria) bloom advisories lifted

November 1, 2017

Revised November 20, 2017

SOUTH ZONE– 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 two bodies of water in South Zone, both of 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:

  • Reesor Lake
  • Bullshead Reservoir
  • Chain Lakes Reservoir
  • Sherburne Reservoir
  • Yellow Lake

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

Alberta Health Services is the provincial health authority responsible for planning and delivering health supports and services for more than four million adults and children living in Alberta. Its mission is to provide a patient-focused, quality health system that is accessible and sustainable for all Albertans.
