Glenavy River: Hundreds of fish threatened by pollution

Mr McCormack suggested that pollution from agriculture is most likely responsible for the fish kill.

The Glenavy River has suffered similar pollution incidents in the past, once in 2020 and in 2014.

Describing the scene at the Glenavy River, Mr McCormack said: “The water is just filled with a brown effluent.

“Normally, this river is sparkling clear and you can see right down to the bottom.”

The Glenavy Conservation and Angling Club accessed grants to open a parkway, a fairy glen for children and fishing stands along the riverbank, making it a popular recreational area.

Young people from the nearby Glenavy Youth Project were confronted by the sight of the dead fish floating at the surface of the river.

“It’s just really harrowing that kids in particular had to witness this incident,” Mr McCormack added.

A spokesman from the Northern Ireland Environment Agency said: “Officers remain on site assessing the extent of the incident and conducting an investigation to determine the possible source of the pollution.”
