The advisory of blue-green algae at Prior Lake in Thetis Lake Regional Park has been cleared.
On Oct. 1, the Capital Regional District (CRD) and Island Health lifted the beach advisory for the toxic-producing algae .
Ingesting water containing the algae may cause headaches and abdominal pain in humans, and can lead to deadly liver damage in dogs.
Recently, water samples collected indicated a ‘below detection limit’ and the CRD has determined that the bloom is over for now.
The warning that was first announced at the end of August is a common problem across the region.
In early September, a blue-green advisory for Beaver Lake in Saanich was lifted. In early January, Elk Lake had the same algae.
Nearby residents are encouraged to keep an eye out for the algae that usually produces a visible blue-green sheen, similar to surface scum. Notably, toxins can be in the water even though you cannot see the scum.
CRD says that blue-green algae blooms are unpredictable and may occur at any time.
