DRYDEN – After receiving a report of blue-green algae bloom in Ghost Lake, the Ministry of Environment, Conservation and Parks is pre-emptively closing the beach to the public while the bloom is being tested.
Although blue-green algae are naturally present in lakes and streams, they are extremely hazardous in large masses.
The Northwestern Health Unit advises the public to avoid drinking the water, swimming in it, and using it for bathing or other household purposes.
Consequently, residential water treatment systems may not remove toxins and should not be relied on during a bloom event.
Do not boil the water, as this can cause an increase in toxin levels.
Municipally treated water supplies can be used normally unless you are notified otherwise.
People and pets should avoid contact with water that has been recently impacted by a blue-green algae bloom, is discoloured or has scum on the surface. If contact does occur, wash with soap and water or rinse thoroughly with clean water to remove algae.
It is recommended to wait at least two weeks after the bloom has disappeared before resuming the normal use of lake waters.
If you spot a bloom, report it to the Spills Action Centre at 1-866-MOETIPS (6638477)
