The Environment Agency have said that Blue Green Algae has been found in Ullswater. The algae is potentially harmful to swimmers. It can also be fatal to dogs.

Blooms of blue-green algae can produce harmful toxins which stop the liver from functioning properly.

A spokesperson for the Environment Agency said, “If you spot algae please call the incident hotline on 0800 807060.

“If you are concerned, please contact Eden Council Environmental Health or seek medical advice.”

Blue-green algae is a term used to describe a group of bacteria, called cyanobacteria.

They are not actually algae, but the organisms got this name because they often give the appearance of algae when they clump together in bodies of water.

The bacteria cannot be seen with the naked eye unless they clump together. When this happens, blue-green algae can look like green flakes, greenish bundles or brown dots in a pond, lake or stream.

When the algae blooms, it can give look like a blue-green scum has appeared on the surface of the water. It sometimes looks a bit like pea soup.

Blooms of the organisms often build up around the edges of ponds and lakes, which may look like foam.

It is most common in non-flowing fresh water such as lakes and ponds during hot weather when there is less rainfall, but can also occur at other times of the year.

You may notice dead fish in ponds or lakes with a high concentration of the toxic bacteria.

The algae may be present in a harmful form even if you cannot see it, so take note of any warning signs in the area.
