An investigation is underway after a pollution incident killed approximately 1,000 fish across the Gransha, Ballystockart, and Inler Rivers in County Down. The Department for Agriculture, Environment and Rural Affairs (Daera) confirmed the report, which was filed by a member of the public at 09:30 GMT on Tuesday.
A Devastating Blow to Spawning Grounds
Glenn McKibbin, secretary of the Inler Angling Club, estimates the death toll includes both brown and migratory sea trout. These smaller tributaries serve as vital nurseries; trout and salmon rely on the cooler, gravel-bottomed waters to spawn safely away from the predators lurking in the mainstem river.
McKibbin noted that the pollution has effectively obliterated both current and future fish stocks for years to come, as it impacted resident fish and migratory species that only return to the river at this time of year to spawn.

Angling Club Demands Stricter Oversight After Pollution Incidents
This is not the first time the Inler Angling Club has faced such a crisis. The river was still struggling to recover from major pollution incidents in 2013 and 2015 when this latest disaster struck. McKibbin remains deeply skeptical of the current oversight, noting that waterways up and down the country continue to be treated like sewers. He argues that the fines typically issued after such events are not a deterrent and described the current system as broken.
The club is now pressing local authorities to prioritize water quality and allocate more resources toward prevention. Chairperson David Pyper highlighted the emotional toll this takes on those who steward the waterways:
For those who dedicate so much time and effort to caring for the river, witnessing the sheer loss of fish in circumstances such as these is particularly disappointing.
