Developed in partnership with Aire Rivers Trust, the Yorkshire Derwent Catchment Partnership, and supported by Yorkshire Water, Rivers to Reef is creating a movement across Yorkshire to protect rivers from their source areas in the hills and moorlands down to the North Sea, with a focus on the Rivers Aire and Derwent. Every year, litter, microplastics, agricultural run-off, sewage, and chemicals enter Yorkshire’s rivers and eventually reach the Humber Estuary and the North Sea.
