Project begins April 2025
The Greater Cambridge Chalk Stream Project (GCCSP) is a focused case study initiative aimed at restoring and protecting some of Cambridgeshire’s most vulnerable chalk streams. These rare, spring-fed rivers support unique ecosystems and provide vital water resources—but are increasingly under pressure from pollution, sedimentation, low flows, and habitat loss.
The GCCSP takes an evidence-based approach, using selected demonstration sites to understand the sources of degradation and evaluate the impact of in-channel restoration. Each site will undergo detailed pre- and post-project monitoring to build a clearer picture of ecological change and the effectiveness of interventions.
In collaboration with Anglia Ruskin University, the project will carry out weekly water quality monitoring at six sites, blending citizen science and academic research. This work will generate local, high-resolution data to pinpoint water quality issues and guide future action.
Importantly, each site will act as a living laboratory, where communities, councils, and decision-makers can come together to collect robust data, raise awareness, and promote the long-term protection of our chalk streams. The goal is to shift restoration from isolated efforts to a coordinated, evidence-driven model.
Key project aims include:
- Identifying specific pollution sources and water quality pressures
- Testing and refining in-channel habitat restoration techniques
- Collecting continuous environmental data to inform future management
- Showcasing regenerative farming practices that support aquifer health
- Empowering local communities through education and citizen monitoring
Sites include rural stretches of the River Granta in Linton and Abington, urban streams like Hobson’s Brook, Coldham’s Brook, and Cherry Hinton Brook, as well as springhead sites and a regenerative farming demonstration at New Shardelowes Farm.
By combining science, innovation, and public involvement, the GCCSP aims to build a stronger case for long-term chalk stream recovery—providing a model for Greater Cambridge and beyond.
