Stanborough lake closed after potentially harmful algae found

Potentially harmful algae has been discovered in one of the lakes in Stanborough Park, Welwyn Garden City.
Blue-green algae, also known as cyanobacteria, was discovered in the south lake last week, and operator Finesse Leisure has since cancelled or moved all water-based activities other than fishing.
Although not all blue-green algae is harmful, some can cause skin rashes, eye irritation, vomiting and diarrhoea, and can also kill wild animals and domestic pets.
A Finesse spokeswoman said: “Naturally occurring blue-green algae has formed on Stanborough’s south lake.
“The Environment Agency, who we informed immediately, has confirmed it is common for this time of year – particularly considering the humid weather conditions recently.
“Although unlikely, contact with the algae can cause illness or rashes and the decision was taken to cancel water-based activities at the lakes. There has been no impact on the fish stock or wildlife.
“We are working with an independent expert, and the Environment Agency, to monitor the situation daily. Public safety is our top priority and we will reopen the lake as soon as water conditions improve.”
A council spokeswoman said it was too early to put a time frame on when that might be, but confirmed some activities had been moved to the north lake.
