Blue-Green Algae Presence in Lake Scugog

Whitby, Ontario - The Durham Region Health Department has been informed by the Ontario Ministry of the Environment, Conservation and Parks that a water sample collected on July 15 from Lake Scugog, near Platten Island, shows the presence of blue-green algae. During the summer months, weather conditions can lead to increased occurrences of blue-green algae in Lake Scugog and other bodies of water in Durham Region. Although there is currently no evidence of blue-green algae at Kinsmen Beach (Palmer Park, Port Perry), advisory signs will be posted there as a precaution due to the historical presence of blue-green algae at this location. Residents are advised not to enter the water if they observe algae mats that may be blue-green, olive-green, or red, as some can produce toxins harmful to humans and pets. Additionally, the lake should not be used as a source of drinking water. Blue-green algae are microscopic, plant-like organisms that can naturally occur in various water bodies. They may appear blue-green, olive-green, or red. To protect themselves and their pets, residents should avoid swimming or playing in discolored water or areas with foam, scum, or algae mats. Children and pets should not play in or drink from areas with posted beach advisories, and consuming fish from these areas is also discouraged. The Health Department monitors 14 public beaches in Durham Region from early June to the end of August, posting information notices about blue-green algae during the monitoring season. If blue-green algae are confirmed at any monitored beaches, advisory signs will be displayed. However, the monitoring program does not cover all accessible lake areas or privately owned waterfront properties, and caution is advised in these locations.
