RESOLVED: Blue-Green Algae Bloom in Elk/Beaver Lake Regional Park

Jul 22, 2020 (updated Aug 19, 2020, 8:05am)

As of Aug 19, the advisory has been lifted for Beaver Lake. Blue-green algae blooms are still present at Thetis Lake and Prior Lake.

The CRD, in consultation with Island Health, has lifted a beach advisory for Beaver Lake in Elk/Beaver Regional Park. Water samples collected indicated a “below detection limit” result for cyanotoxins. The extended absence of blue-green scum combined with test results are good indicators that the bloom is over. 

Park users are reminded to watch for the distinctive blue-green sheen, which can appear on the lake surface. Blue-green algae blooms are unpredictable and may occur at any time. These algae are known toxin producers. Ingesting water containing these cyanotoxins may cause a range of symptoms, including headaches and abdominal pain in humans, and can lead to lethal liver damage in dogs.
