Project summary

Edit project overview to modify the project summary.


The Wansbeck and many of its tributaries are currently viewed as ‘failing’ under the requirements of the Water Framework Directive (WFD). The main reason for failure is numbers of fish. The main issue behind this appears to be the amount of silt, sediment and nutrients that are washed into the rivers and streams from farmland and forests. Other factors include weirs that hold up fish migration, and a lack of bank-side and in-stream habitat. This ambitious community project aims to help address these issues, and improve the quality, WFD status and local enjoyment of 100km of river and stream. The rivers and streams that are part of the project include:The Upper Wansbeck; The Font; The Hartburn; The Delf Burn; The Ray Burn. The project will work closely with schools and communities to help renew local interest and ‘ownership’ of the rivers in this rural part of Northumberland. Outputs will include: improvements to fish passage; lengths of fenced buffer strip to filter out sediments; new and improved wetland features to settle out sediment and nutrients; improvements to vehicle crossings; new native woodland; work with farmers and land managers to reduce run-off in ways that reduce their costs; engagement and communications activity with schools, communities and angling clubs.
