Third fish kill incident for town

Trout, roach and stone loach were killed

Another fish kill is being investigated by the Environment Agency in Portadown - the third such incident in the area in recent weeks.

It happened on the Ballybay River at Corcrain, which is close to a nature reserve and a natural wetland.

Trout, roach and stone loach are among the species that have been killed.

"Water quality inspectors have been assessing the damage and trying to establish what happened," said an Environment Agency spokesman.

"In the inspectors' opinion, a plug of pollution has travelled down the river which was in flood at the time.

"Measurements of dissolved oxygen levels in the river were very low and samples have been taken for analysis in an attempt to discover the nature of the pollutant."
