WALKERS and pet owners are being warned about toxic algae found near a popular Barrhead trail.
Concerns have been raised after a high concentration of blue-green algae – also known as cyanobacteria – was found in water at the Balgray Reservoir.
Blue-green algae may appear as green or greenish-brown scum on the surface of water and can contain toxins that are harmful for animals if ingested, even in small quantities.
Dogs can swallow this algae by drinking from an affected waterway or while licking their fur after going for a swim.
People visiting the trail are being warned not to swim, paddle or fish in the reservoir and to be cautious of allowing their dogs to swim or drink there.
