NI Water is reminding everyone visiting loughs, lakes and rivers this summer to take simple steps to prevent the spread of invasive species.

With more people enjoying boating, angling, paddleboarding and other water-based activities during August, NI Water is encouraging the public to follow the Check, Clean, Dry approach before moving between waterways.

Invasive non-native species can be carried in tiny amounts of water, mud or plant material on boats, clothing, footwear, fishing gear and other equipment. Once introduced, they can damage native wildlife, affect water quality, block waterways and cause costly disruption to water infrastructure.

NI Water is particularly mindful of the threat posed by aquatic invasive species such as zebra mussels and quagga mussels, which can attach to hard surfaces and spread quickly between connected waters.

NI Water Catchment Manager Roy Taylor said: “August is one of the busiest times of year for recreational use of our waterways, and that means there is a greater risk of invasive species being moved from one location to another.

“Invasive species can have a serious and lasting impact on the water environment. They can outcompete native plants and animals, alter habitats and cause operational challenges by clogging screens, pipes and other equipment used to abstract and treat water.

“Prevention is our best defence. By checking, cleaning and drying boats, clothing and equipment every time you leave the water, everyone can play their part in protecting our waterways.”

Check, Clean, Dry:

  • Check boats, equipment, footwear and clothing for mud, aquatic animals or plant material before leaving the water.
  • Clean everything thoroughly as soon as possible, paying particular attention to ropes, bilges, trailers and areas that stay damp or are hard to access. Use hot water where possible.
  • Dry all equipment and clothing for as long as possible before using it elsewhere, as some invasive species can survive for days or even weeks in damp conditions
