Victorians hoping to take a dip in Prior Lake this afternoon would do better to pick a different water body.
As of Thursday, the CRD has issued an advisory against swimming in Prior Lake – located at the north end of Thetis Lake Regional Park – due to the presence of toxic blue-green algae.
When present, the algae usually produces a visible blue-green sheen, which appears as surface scum. However, not all blooms are easy to see and toxins can still be present in the water even if you cannot see them.

If ingested, the algae can cause a range of harmful symptoms, including headaches and abdominal pains. For other animals, like dogs, it could also cause lethal liver damage.
During toxic blue-green algae warnings, the CRD advises against entering the water and keeping pets on leashes.
