Calgary Blue-green algae bloom advisories lifted

November 6, 2019

CALGARY – 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 water bodies which had previously been placed under blue-green algae (cyanobacteria) bloom advisories in the Calgary Zone of Alberta Health Services (AHS).

Effective immediately, AHS has lifted the blue-green algae (cyanobacteria) bloom advisories for Twin Valley Reservoir and Clear 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.

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.
