Halifax Regional Municipality is warning people to avoid swimming at Cunard Lake Beach in Halifax due to a possible blue-green algae bloom. Blue-green algae, or cyanobacteria, are microscopic bacteria that live in surface water like lakes, ponds, rivers and streams that can be dangerous to people and pets. The organisms can multiply rapidly during the hot summer months and may release toxins into the water when the blooms die.
Blue-green algae confirmed in Shelter Bay on Lower Shebandowan Lake
The Thunder Bay District Health Unit is warning people to avoid the water at Shelter Bay on Lower Shebandowan Lake after tests confirmed the presence of blue-green algae. The health unit said some blue-green algae blooms produce toxins that pose health risks to people and animals, and the water at Shelter Bay should be avoided while the bloom is present, and for about two weeks after it dissipates.
Risk advisory in effect for Lake Banook after possible algae bloom
Swimmers are being asked to avoid Dartmouth's popular Lake Banook due to a possible blue-green algae bloom. A release from the Halifax Regional Municipality Sunday afternoon announced a risk advisory was in effect for Birch Cove Beach, and people were asked to avoid swimming there until further notice. City staff are currently investigating whether or not it is a toxin-producing algae, the release said. Blue-green algae naturally occurs in freshwater environments and can multiply rapidly during the summer, leading to extensive growth called a bloom. Some types of this algae produce toxins during blooms and those toxins may leak into the water when the bloom fades, the release said.
