Project summary

Edit project overview to modify the project summary.

The River Eden River Restoration Strategy (RERRS) is a partnership project involving Eden Rivers Trust, the Environment Agency and Natural England, working with land owners and farmers. It aims to return rivers in the Eden catchment to a more natural state for the benefit of wildlife and people. It was developed as a remedy for the unfavourable condition of large parts of the River Eden and Tributaries Site of Special Scientific Interest.

On the River Lyvennet and Howe Beck at Barnskew and Meaburn Hall, Maulds Meaburn the rivers were restored to their original winding channels with approximately 1500 m of straightened river now meandering through nearly 1900 m. The project was undertaken in 2014 and an estimated 11,000 cubic metres of soil weighing approximately 15,000 metric tonnes was excavated. Very soon after the Lyvennet was diverted into its new channel, salmon were seen spawning in the river where they had not been seen spawning before. The site is a demonstrations of river restoration techniques and the many benefits this approach can bring to wildlife and people.

Monitoring surveys and results
