Toxic blue-green algae blooms have reappeared across water systems in Northern Ireland, leading to widespread closures and significant disruption for local businesses and residents. According to the UK Centre for Ecology and Hydrology, there are currently 247 algae blooms present, with 80 confirmed in June and July alone. The Department of Agriculture, Environment and Rural Affairs (Daera) has identified affected areas including Camlough Lake near Newry and Craigavon Lakes.
Karl Toner, who owns a coffee cart, a glamping site, and a paddleboard hire business at Camlough Lake, reported a sharp decline in visitor numbers since a warning was issued on July 13. "In the summertime this place really goes off, now the algae has just completely killed it," Toner stated. He noted that warm weather typically draws hundreds of visitors daily from across Northern Ireland and beyond, providing a substantial boost to local trade. However, the presence of algae has led to the lake becoming deserted.
The toxic bacteria can cause skin irritation and illness in humans and animals that come into contact with it, prompting advisories against swimming and water sports. The closures have effectively turned popular summer destinations into unusable spaces, likened by some to "having an amusement park and not opening it." MOBILE_IMAGE_1
Impact on Businesses and Recreation
The economic impact is being felt keenly by businesses reliant on lake tourism. Toner's experience highlights the dependence of local enterprises on the accessibility and appeal of these natural sites during peak season. The current situation has led to a dramatic reduction in activity, impacting revenue and local employment opportunities. The widespread presence of algae across numerous water bodies suggests a persistent environmental challenge for the region during warmer months. These blooms are a recurring issue during recent summers, underscoring the need for ongoing monitoring and management strategies to mitigate their effects on both the environment and the local economy.
