North Lincolnshire Council has warned dog walkers to stay away from a potentially toxic lake in Scunthorpe.
The Blue Lagoon lake in a nature reserve off Normanby Road is covered in blue-green algae and officials are working to see if it is toxic.
Experts from the Environment Agency will assess the water over the next ten days to see if it is the toxic strain of the bacteria.
Blue-green algae can produce toxins harmful to both humans and animals, which dogs could consume if they go for a swim.
If left untreated, the toxins produced by blue-green algae can be ultimately fatal for dogs.
The British Veterinary Association has seen a rise in toxic blue-green algae cases in Lincolnshire, Derbyshire, and Leicestershire.
⚠️ Dog owners are warned not to allow their dogs to swim in Blue Lagoon, off Normanby Rd, due to potentially toxic blue green algae. We're working alongside the @EnvAgency to see if it is a toxic strain, – this can take around ten days.

British Veterinary Association junior vice president Daniella Dos Santos said: “While not all blue-green algae are poisonous, it is impossible to tell the difference visually, so it is better to be safe than sorry.
“There is currently no known antidote for the toxins, so prompt veterinary treatment is essential to tackle their effects and ensure a good chance of recovery.
“If you suspect your dog has been exposed to blue-green algae, rush it to your local vet without delay.”
