Project summary
The Sherborne Windrush Restoration Project is a partnership project that will use CRF funds to improve the River Windrush and the Sherborne Brook in the Sherborne area of Gloucestershire.
The river suffers from a degraded habitat aris-ing from insensitive dredging which has removed river bed gravels and built up banks causing a disconnect from the water meadows as well as suppressing in stream habitat varia-tion. There are also problems caused by dif-fuse agricultural pollution and areas of over sharing. These issues are preventing this stretch of water from meeting the required standards under the Water Framework Directive (WFD). This project will build on the work already completed by addressing the following issues: inadequate levels of fish spawning gravels; lack of in-stream habitat variation; pollution from agricultural run off; poaching of the banks by cattle; lack of hydrological connectivity with the flood plain; over shading by streamside vegetation.
