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.

A spokesperson for East Renfrewshire Council told the Barrhead News: “Algal scum can form on the surface of water due to warmer weather during the summer months.

“It can be harmful to health, so you should not swim, paddle or fish in the Balgray Reservoir until it clears. This advice also applies to dogs.

“Our park rangers and environmental health team will continue to monitor the situation.”

In animals, symptoms of exposure can appear within a few minutes or hours, depending on the type of toxin ingested, and commonly include vomiting, diarrhoea, disorientation, breathing difficulties and seizures.

If left untreated, the toxins can cause liver damage.

Dog owners are advised to keep their pets on a lead when visiting Balgray Reservoir.

Anyone whose dog does swim there should wash its coat thoroughly with clean water afterwards.

Chief superintendent Mike Flynn, of the Scottish SPCA, said: “Any dog owners concerned that their dog has come into contact with blue-green algae should consult their vet immediately.

“If you find algae, this should be reported to the local authority’s environmental services.”
