Project summary

Edit project overview to modify the project summary.


Clear the scrub and some canopy to improve light penetration to the river. Flow & width adjustments for wider areas to create viable pool-riffle system. Despite trout spawning in the area, some habitat is degraded and silt covers gravel.
Planned and in discussion for funding and delivery

Funding - Environment Agency Or Wild Trout Trust (Cinderella Project)
