Natural Resources Wales (NRW) is appealing for information following a pollution incident that killed hundreds of fish on Saturday 2 July.

NRW officers are investigating the incident on the afon Llynfi, a tributary of the river Wye, near Three Cocks, Brecon.

Two officers were sent to investigate on Saturday evening to look for signs of pollution and attempt to find the cause of this significant loss of fish.

Initial reports had found over 50 fish had been killed. An on-going assessment of the impact of the incident has reported hundreds of fish killed, which includes brown trout and bullheads.

Steve Morgan, South East Operations Manager for Natural Resources Wales, said:

“Our rivers provide a home to rich, diverse and valuable species of plants and animals so it’s important to deal with pollution as quickly as possible.
