IFI secures conviction against Uisce Éireann for sewage pollution that killed almost 1,000 fish
- Fine of €4,000, and more than €7,100 in costs/expenses imposed
Inland Fisheries Ireland(IFI) has welcomed a conviction against Uisce Éireann after a sewage discharge polluted a popular angling lake in Co Mayo.
Effluent from Uisce Éireann’s wastewater pumping station in Claremorris flowed into Clare Lake, killing at least 945 fish over a two-week period.
The company was found to have committed a water pollution breach, and must pay a fine of €4,000 and €7,131 in costs and expenses to IFI.

Commenting, Dr Rachel Cooper IFI’s Galway Director, said: “A large number of fish, including perch and roach, were impacted in this very damaging event. It may take years for Clare Lake to recover.
"Pollution incidents such as these severely affect water quality and pose a serious threat to our natural environment, and fish stocks."
The lake is a well-used and very important local angling amenity, with floating fishing stands, wheelchair access, and seating areas for members of the public.
These works were completed by IFI in 2016, in conjunction with a local Community Employment Scheme initiative.

The case was heard at Castlebar District Court, on January 7th, 2025.
The incident occurred on April 26th, 2024 and may have also had a secondary impact on water quality in the River Robe as the lake forms part of its catchment.
IFI continues to urge the public to report instances of water pollution, fish kills, habitat destruction, or illegal fishing, to its confidential 24/7 number, 0818 34 74 24.
