Guidance advising against water activities in a Powys lake where immersion in water is likely, after blue-green algae was identified, have now been lifted, the county council has announced.
The council’s Environmental Health Service has lifted previous guidance regarding Llangorse Lake as the last two consecutive weekly samples showed that the lake to be free of blue green algae. The guidance was first issued last month (June) when the lake was first affected by the potentially toxic blue green algae.
Although recreational activities can now resume on the lake, both the council and the Environment Agency Wales will continue to monitor the lake as the blue green algae could grow to excess again in suitable conditions.
Steve Clinton, the council’s Public Protection Manager, said: “Weekly samples have been taken at Llangorse Lake since the blue-green algae was identified. The last two samples have shown that the lake to be free of the potentially toxic algae.
“We have now lifted the guidance, which was put into place to protect members of the public and animals. However, we will continue to work closely with the Environment Agency Wales in monitoring the lake as the blue green algae could grow again in suitable environmental conditions.”
Dai Walters, from Environment Agency Wales: “Our officers have been monitoring the lake very closely since we first identified the presence of Blue Green Algae last month.
“We’re pleased to say that the lake is currently clear of the algae, but we won’t be complacent, and we will continue to monitor the lake. We are also working with our partners to investigate the conditions which cause the algal bloom so we can reduce the likelihood of it reoccurring in the future.”
Samantha Games, PR Officer for Brecon Beacons National Park Authority, said: “Llangorse Lake is a popular destination for both local residents and visitors, who will welcome the news that the guidance has now been lifted, especially when the weather forecast is set to improve over the coming days.
“We will continue to work closely with our partners by monitoring the Llangasty side of the lake and informing them of any developments.”
