Farmers in Wales encouraged to seek advice before river work

Farmers and landowners in Wales are being urged to seek expert advice before working in rivers, as poorly planned activity can cause environmental damage, legal issues and significant financial costs.

Natural Resources Wales (NRW) says activities such as removing gravel, reshaping riverbanks or straightening channels can unintentionally worsen erosion, increase flood risk and damage habitats.

For farm businesses, these impacts may also extend beyond field boundaries, affecting neighbouring land and infrastructure and potentially resulting in liability claims or expensive repairs.

NRW officials stress that many of these issues could be avoided if landowners consult the regulator at an early stage.

Understanding regulations

Early advice can help farmers understand which permissions are required and how to carry out work effectively and in compliance with environmental rules.

NRW specialist adviser for freshwater habitats and species, Francesca Sanchez, said: “We’re asking landowners to get in touch with us before they start any work in a river or stream.

“Far too often, we hear about these activities only after something has gone wrong, and by that point landowners could face stop notices, costly restoration and enforcement action.”

The warning comes as natural river features, such as gravel shoals, which are important for fish spawning and biodiversity, have declined by more than half in Wales over the past century.

Disturbing these features can destabilise river systems for years and trigger enforcement action.

“A simple call at the start could prevent all of that,” added Ms Sanchez.

Available guidance

Most work within or alongside watercourses requires formal consent from NRW or local authorities, and carrying out work without the necessary permits may constitute an offence.

NRW says its officers can guide farmers through the application process and advise on practical approaches that protect both land and environment.

“It’s always better to check what permissions you need before you carry out any work in a river or stream.

“It’s better for nature and for the landowner,” Ms Sanchez added.

Landowners planning work in a river or stream can contact NRW for advice on 0300 065 3000 or email enquiries@naturalresourceswales.gov.uk.

Suspected illegal activity in rivers can be reported to the same number.
