A spokesperson for the Loughs Agency said the body was currently attending the scene of an extensive pollution incident on the Aghlisk River, a tributary of the Owenreagh in Co. Tyrone. It comes just days after the Department of Agriculture, Environmental and Rural Affairs published details of how it plans to reduce agricultural run-off in its new River Basin Management Plan. “Loughs Agency fishery officers were alerted to the incident via a report received at 6:30pm on Sunday, May 2, 2021,” the Loughs Agency spokesperson said.
