Toxic Blue Algae Found in New Pond

The New Pond is experiencing an early onset of a blue-green algae bloom, a phenomenon typically observed around mid to late August. This unusual event is thought to be a result of the exceptionally warm and dry conditions experienced in June.

Blue-green algae, scientifically known as Cyanobacteria, are not algae but bacteria. They thrive in warm temperatures and still water, making the New Pond an ideal breeding ground. The typical bloom period in ponds like the New Pond occurs during the summer months, with higher risk in the warmer summer months.

While the current weather conditions are cool, the blue-green algae are still appearing in the New Pond. It's important to note that some species of Cyanobacteria can produce a toxin, posing a health risk to both animals and humans. However, precautionary measures are being taken as it is very unlikely that blue-green algae toxins will be present in a "carpet-like spread."

The health authority does not regulate the quality of water in non-swimming lakes like the New Pond. The risk to animals from blue-green algae in the New Pond is a potential concern, and pet owners are advised to be vigilant. The health risk from blue-green algae is primarily through drinking the water, such as if a dog drinks while swimming.

Initially, there is no direct danger to humans from the blue-green algae in the New Pond, as it is not a swimming lake. However, the risk to humans would increase if it were to become a swimming lake.

In some cases, the blue-green algae in the New Pond can turn a metallic blue colour, and blue-green algae streaks are appearing. Sometimes, this metallic blue tint is added later in their season.

It's crucial to monitor the situation closely and adhere to any warnings or instructions issued by local authorities. The quality of swimming lakes is controlled, and they may be closed by the health authority at certain threshold values.

Stay informed and take necessary precautions to ensure the safety of both yourself and your pets.
