Blue-Green Algae Alert: Hemlington Lake Water Deemed Potentially Toxic to People and Pets
Tests carried out by the Environment Agency on the water at Hemlington Lake have shown that blue/green algae levels are above the warning threshold.
The high levels make the water potentially toxic to humans and dogs, especially if it's ingested.
We are advising people to stay out of the water and keep pets well clear.
The algae occurs naturally, and Middlesbrough Council will provide an update when further tests are carried out.
🚨Algae Bloom at Hemlington Lake 🚨
We have been made aware of a severe algae bloom currently affecting Hemlington Lake🦠
⚠️ Do not allow pets to swim, drink, or come near the water.
We are awaiting further updates and guidance from the Environment Agency, and we will share any new information as it becomes available.
