Blue Green Algae Bloom Notice for Silver Lake - September 9, 2024

Results have been received from the Ministry of the Environment, Conservation and Parks (MECP) confirming a blue-green algae bloom in Silver Lake. 

Many species of blue-green algae (also called cyanobacteria) have the potential to produce toxins that are harmful to the health of humans and animals when exposed in large amounts. Due to the confirmed presence of the bloom, we are asking residents and visitors to exercise caution and recognize that toxins may also be present.

As a precautionary measure, the SMDHU urges residents and businesses to avoid drawing or drinking water from private water supplies that are impacted by the lake where blue-green algae has been identified and to take the following precautions:

▪ Do not use a private water supply that is impacted or draws water from this area of the lake for the preparation of infant formula.
▪ Do not allow pets or livestock to drink or swim in the water where an algae bloom is visible.
▪ Fish taken from waters with cyanobacterial blooms have the potential to contain toxins. Exercise caution when eating fish caught in water where blue-green algae blooms occur.
▪ Do not use herbicides, copper sulphate or other algaecides that may break open algae cells and release toxins into the water.
▪ Avoid water sport activities where an algae bloom is visible.

The health unit and the Ministry of Environment, Conservation and Parks will continue to work together to monitor the algal bloom and updates will be provided on our website www.smdhu.org/algae.
