Hidden beneath the surface of the River Frome lies a quiet problem. From weirs to culverts, over a hundred barriers interrupt the flow of water and life along this Gloucestershire river and its key tributary, the Nailsworth Stream. These structures fragment vital freshwater habitat and prevent fish from reaching their spawning and feeding grounds. The Frome Fish Barrier Appraisal and Prioritisation project set out to change that.
Led by Severn Rivers Trust as part of the Wilder Frome flagship under the Severn Vale Catchment Partnership, the project brought together local expertise and ambition. Between April 2024 and March 2025, we assessed 100 known barriers to fish migration across the catchment. This work provided a crucial baseline to help us understand which sites offer the best opportunities for restoration.
To guide our decisions, we created a bespoke prioritisation matrix with input from the newly formed Frome Fish Pass Working Group. This group, made up of representatives from five local organisations, agreed on criteria to assess each site. The result is a clear and strategic approach to improving fish passage where it will make the most difference.
Two priority sites were selected and taken through an options appraisal. We now have outline designs in place for fish passes or full barrier removals at both locations. These concept plans will help the Working Group move forward with fundraising and delivery, forming the first steps in a wider vision to reconnect the Frome for wildlife and people alike.
The project has been made possible through support from the Environment Agency’s Water Environment Improvement Fund (WEIF), with match funding provided by Stroud District Council.
A partnership built on shared ambition
The project has already sparked a renewed sense of collaboration. The creation of the Working Group marks a long-term commitment to improving fish habitat and building resilience across the catchment. It brings together the knowledge, passion and local presence needed to take real action.
“This project has provided an invaluable baseline assessment of fish passage in the Frome and galvanised local partners around a collective ambition to pursue a long-term programme of easements and removals, so that we might see thriving fish populations in future,” said Chloe Hatton, Severn Rivers Trust’s Catchment Restoration Officer.
Looking ahead
In one year, we’ll have detailed designs and delivery plans in place. In five, we hope to see completed fish passes and open migration routes. In ten, the Frome could once again be home to healthy, thriving fish populations making their natural journeys through a connected river system.
As this work moves from planning to delivery, we’ll continue to share updates and opportunities to get involved. Whether you’re a local resident, angler or river enthusiast, your support helps make projects like this possible.
By removing barriers and restoring flow, we’re not just helping fish move more freely. We’re making space for nature, for people and for a better future along the River Frome.
