WATER activities on the lake in Llandrindod Wells have been immediately suspended following a suspected algae outbreak.

Lakeside Boathouse made the announcement on Sunday, August 15, confirming that all watersports and fishing would be cancelled until further notice.

“Due to a suspected outbreak of blue/green algae we have been advised to close the lake to people wanting to fish or paddle as from Monday, August 16,” Lakeside Boathouse said on its Facebook page.

“We will only be running the dragon boats during this time.”

The lake has proved hugely popular this summer with the boathouse launching a brand new watersports programme of events including rafting, kayaking and paddle boarding. Environmental health officers from Powys County Council were due to inspect the possible outbreak today (August 16) and the boathouse says it hopes activities can resume as soon as possible.

“The Powys outdoor recreation officer will arrange for environmental health to sample and test the water on Monday and if the results are negative we will re-open the lake as early as possible,” the statement from the boathouse continued.

“Your co-operation in this matter is much appreciated. As soon as we have any more information it will be posted on this page.”

A spokesman for the local authority said testing has been carried out on the lake and they are awaiting results. “Testing has been carried out on Llandrindod Lake due to a suspected outbreak of blue-green algae," they said.

"The council is waiting for the results of the testing from Natural Resources Wales. As a precautionary measure, the operator has suspended immersive activities on the lake.”
