RESOLVED: Blue-green algae bloom at Elk Lake in Elk/Beaver Lake Regional Park

Apr 11, 2020 (updated Apr 28, 2020, 9:24am)

As of Apr 28, the advisory has been lifted at Elk Lake. However, blue-green algae blooms are unpredictable and may occur at any time.

The blue-green algae advisory is now lifted for Elk Lake, located in Elk/Beaver Lake 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 that can appear on the lake surface 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.
