As locals and visitors make the trip to Northern Ireland’s lakes in search of summer sunshine, they are once again facing an unwelcome sight: blue-green algae.
The toxic bacteria which can cause skin irritation and sickness in people and animals who come into contact with it, has become an unwelcome feature of recent summers.
There are currently 247 algae blooms across Lough Neagh and Northern Ireland’s water systems, according to the UK Centre for Ecology and Hydrology, external. Eighty have been confirmed in June and July alone.
The Department of Agriculture, Environment and Rural Affairs (Daera) said two of the areas affected are Camlough Lake near Newry and Craigavon Lakes.
For one business owner based at Camlough Lake, the return of blue-green algae has had an immediate impact.
Karl Toner, who owns a coffee cart on the shore as well as a nearby glamping site and paddleboard hire business, said visitor numbers have fallen sharply since the warning was issued on 13 July.
“In the summertime this place really goes off, now the algae has just completely killed it,” he said.
Toner explained how warm weather would normally bring visitors from across Northern Ireland and beyond to the area, providing a trade boost.
“On a good day, there would be hundreds of people here from the morning right through until midnight, swimming and enjoying the lake, but now the place is empty,” he said.
