The Northwestern Health Unit has confirmed that the bloom spotted and tested in Rice Bay on Rainy Lake earlier this month is blue-green algae.
The health unit said results of the sample show that toxins were present that exceed the Ontario Drinking Water Standard and Recreational Water Standard.
It added that since the testing was earlier this month, concentrations may now be higher or lower, depending on how the bloom has evolved, Also the bloom can move and may not be localized to a single location on the lake.
With the presence of the blue-green algae, the health unit said it is important to avoid drinking the water, swimming in it, and using it for bathing or other household purposes. Municipally treated water supplies can be used normally unless you are notified otherwise.
The health unit said if contact does occur between the algae bloom and people and pets, wash with soap and water or rinse thoroughly with clean water to remove algae. At least two weeks should pass after the bloom has disappeared before using lake waters again.
