THE PUBLIC have been asked to take care after reports of blue-green algae in Derwent Water.

The UK Centre for Ecology and Hydrology has reported blue-green algae in Ullswater near Pooley Bridge.

Blue-green algae poses a risk to the health of both humans and their pets as their blooms produce toxins that can cause skin rashes and more severe symptoms if consumed.

The centre's advice is to keep children and dogs away from the water where blue-green algae has been spotted.

They also advise that dogs are kept on a lead and carry a bottle of water.

They said: "If you or your pet become unwell after contact with water that may be contaminated with blue-green algae, we'd recommend you seek immediate medical or veterinary advice."

If a bloom of blue-green algae is spotted, the public can report it via the Bloomin Algae app.

It is also advised that you contact your Local Authority's environmental health department.

Blue-green algae first develops as small green particles of 1-2mm. If the bloom develops it can become more obvious, collecting on the surface of the water.
