RESOLVED: Beaver Lake Tests Positive for Blue-Green Algae

Aug 09, 2019 (updated Sep 05, 2019, 3:02pm)

As of Sept 5, the advisory has been lifted at Beaver Lake. However, blue-green algae blooms are unpredictable and may occur at any time.

The CRD, in consultation with Island Health, has lifted a beach advisory for Beaver Lake, located in Elk/Beaver Lake Regional Park. Samples collected at the beach 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 that can appear on the lake surface. Blue-green algae blooms are unpredictable and may occur at any time. These blue-green algae are known toxin producers. Ingesting water containing the blue-green algae may cause a range of symptoms, including headaches and abdominal pain in humans, and can lead to lethal liver damage in dogs.
