Project summary

Edit project overview to modify the project summary.

Many watercourses within the River Rea Catchment are failing to meet the required standards under the Water Framework Directive (WFD) due to failing fish numbers. The River Rea has long been known as a catchment in serious decline as a result of sedimentation, poor agricultural practices and fish migration barriers. The Severn Rivers Trust walkover surveys of the River Rea, confirmed that suspended sediment load is seen to be impacting on the ecological health of the river and a major cause of fish failure. Impacts such as agricultural run-off from fields and bank erosion caused by farm animals are major contributors to an excessive quantity of sediment entering the river system. Also good riparian habitats are in decline due to over shading and over mature and diseased alders dying and falling into the river causing excessive blockages and bank erosion scars.

It is seen as an integral part of an integrated catchment management approach.
