Inland Fisheries Ireland (IFI) investigated a pollution incident that occurred last weekend on the Carrowbeg River in Westport, Co Mayo.

IFI received a number of calls to the hotline number and had a report from the landowner where the pollution incident occurred last Saturday 16 January.

Fisheries staff responded to the report of what’s understood to be an accidental detergent discharge into the Carrowbeg River that afternoon.

The Carrowbeg River is the main river that runs through Westport town and has an abundant indigenous brown trout population, as well as being is an important amenity to the local community.

IFI officers attended the scene and worked with the landowner to identify the source and to carry out immediate remedial works.

IFI says its staff continue to monitor the site and carried out kayak and drone surveys of the catchment area over the weekend to assess implications for the fishery. Surveys to date have not found any evidence of a fish kill resulting from the incident.

IFI says it has had “subsequent engagement with the landowner regarding remediation works to be undertaken at the site” and is liaising with with Mayo County Council’s Environmental Section on analysis of samples from the affected stretch of river.

Patrick Gorman, Galway director in the Western River Basin District at IFI, says: “Inland Fisheries Ireland urges members of the public to be aware of the environmental risk posed to their local waterbodies should such discharges be made into road or car park drain networks.

“Members of the public can report suspected pollution or poaching incidents to Inland Fisheries Ireland’s 24-hour confidential hotline on 1890 34 74 24.”
