TOXIC blue-green algae has been detected at a popular Furness fishing spot, prompting a warning to anglers.

The Environment Agency has found evidence of a blue-green algal bloom in a section of water at Pennington Reservoir, near Ulverston.

The news comes a week after localised blue-green algae was reported on Windermere at Ferry Nab.

South Lakeland District Council  is urging people to treat all blue green algae blooms with caution and contact should be avoided as skin rashes and illness may occur if the water is swallowed.

Anglers who fish at Pennington reservoir are being warned that any fish should not be caught for human consumption during a toxic blue-green algal bloom.

SLDC’s Principal Environmental Protection Officer, Sean Hall, said: “Blue-green algae can potentially make people feel quite ill if swallowed or even by just swimming in it. 

“We want the public to be aware of the effects and are asking people to be extra careful and vigilant when using the lakes, rivers and reservoirs for recreational purposes during the summer months. 

“Farmers and pet owners should also prevent livestock and animals coming into contact or drinking the affected water, as it can sometimes prove fatal for animals.

“People should observe any notices near affected areas and avoid contact or drinking water from areas identified.”

Many standing waters are vulnerable to problems with blue-green algae, typically between June and November. 

All blue-green algae blooms should be assumed to be toxic and the blooms vary in colour from discoloured green, blue-green, greenish brown, or reddish brown. The blooms do subside and this is a temporary situation.
