The CRD has closed Beaver Lake because of a blue-green algae bloom.
The Lake has been closed to swimmers while a sample of the water is tested for toxins.
Visitors are advised to avoid swimming at Beaver Lake and to keep animals on a leash to prevent them from drinking or swimming in the water.
The algae usually produce 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 the algal blooms.
Algae blooms are unpredictable and produce toxins which have been detected previously in Elk and Beaver Lakes.
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.
