Project summary
The Sherborne Windrush Restoration Project is a partnership project that will use CRF funds to improve the River Windrush and the Sher-borne Brook in the Sherborne area of Glouces-tershire.
The river suffers from a degraded habitat aris-ing from insensitive dredging which has re-moved 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 Di-rective (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.
