The River Gade has been restored to its natural course through Gadebridge Park in Hemel Hempstead, enhancing local biodiversity and reducing flood risks.
This significant project, led by the Environment Agency with partners, reconnects the chalk stream to its floodplain, benefiting both wildlife and community recreation.
Restoration of a Rare Chalk Stream
The River Gade’s restoration is a landmark achievement for environmental conservation in the UK. Chalk streams are globally rare, with 85% located in England.
This project not only restores the river’s natural flow but also improves water quality and resilience against droughts by re-routing spring flows previously diverted underground.
Vegetated margins have been created along the riverbanks to support aquatic insects, juvenile trout, water voles, and otters.
These enhancements contribute significantly to local biodiversity while reducing sediment build-up that previously narrowed the artificial channel.
Community Benefits
- Improved access to natural river environments for residents and visitors
- Enhanced recreational facilities in Gadebridge Park
- Reduced local flooding risk protecting properties and infrastructure
- Healthier ecosystems supporting fishing and wildlife watching
- Sustainable water supply management benefiting household availability
A Collaborative Effort for Environmental Restoration
This ambitious project was a collaborative effort involving the Environment Agency, Affinity Water, Dacorum Borough Council, and BAM Nuttall.
Construction began in Autumn 2024 and concluded in June 2025. The project aligns with broader UK government policies focused on restoring natural habitats and floodplains.
Innovative Solutions for Ecological Connectivity
An innovative ultrasonic structure was installed to facilitate fish and mammal movement while redirecting spring flows.
This cutting-edge ecological engineering solution supports biodiversity and may serve as a model for future UK river restoration projects.
Stakeholder Comments
Chris Wilson, area director at the Environment Agency, said:
“Getting to this stage marks the huge collective effort of a large number of people, not just at the Environment Agency, but from our partners, Dacorum Borough Council and Affinity Water, our contractors, JBA, BAM Nuttall and Arcadis and many, many others besides.
I’d like to thank everyone involved for their perseverance and commitment to bringing such a complex and ambitious project to completion.”
Councillor Robin Bromham, portfolio holder for neighbourhood operations at Dacorum Borough Council, added:
“This is a landmark moment for Gadebridge Park and for our local environment. The return of the River Gade to its natural course not only restores an important ecosystem but also enhances the park experience for our residents and visitors.
We’re proud to have worked with our partners to deliver this project that benefits both people and nature.”
