Blue-Green Algae Information

A blue-green algae (cyanobacteria) bloom has been identified in a pond at the Three Mile Bend off-leash dog park, Bower Ponds and McKenzie Trails.

As a result, an Advisory is in place from Alberta Health Services. This Advisory will remain in place until a rescind notice is issued. While the advisory is in place residents should take the following precautions:

  • Avoid all contact with algae blooms. If contact occurs, wash with tap water as soon as possible.
  • Do not swim or wade (or allow your pets to swim or wade) in any areas where algae is visible.
  • Do not feed whole fish or fish trimmings from this pond to your pets.
  • Consider limiting human consumption of whole fish and fish trimmings from the pond, as it is known that fish may store toxins in their liver. (People can safely consume fish fillets from this pond).
  • As always, never drink or cook with untreated water directly from any pond or lake, including Three Mile Bend, at any time. Boiling pond or lake water will not remove the toxins produced by blue-green algae (cyanobacteria). An alternate source of drinking water should be provided for pets while this advisory is active.

Note: areas of the pond that do not have visible blooms can still be used for recreational purposes, even when an Advisory is in place.
