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

Jul 22, 2020 (updated Aug 05, 2020, 2:23pm)

As of Aug 5, this advisory for Beaver Lake remains in effect. We continue to monitor water quality in the lake.

The Capital Regional District (CRD) advises, in consultation with Island Health, that there is a blue-green algae bloom at Beaver Lake located in Elk/Beaver Lake Regional Park. At this time, this advisory does not include Elk Lake. However blooms are unpredictable and may occur at any time.

Blue-green algae can produce cyanotoxins. Visitors are advised to avoid swimming in the lake and to keep animals on a leash to prevent them from drinking or swimming in the lake until the advisory has been lifted.

The algae usually produce a visible blue-green sheen, which appears as surface scum on the water. Not all blooms are easy to see and toxins can still be present in the water even if you cannot see a bloom.

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.
