The River Hull Headwaters nature reserve was purchased in 2008 as two grass fields – Snakeholm Pastures, adjacent to the Wansford Bridge, some four miles southeast of Driffield, in the heart of East Yorkshire. Then, in 2011 Yorkshire Wildlife Trust bought what at the time was a commercial fish farm covering 33 hectares along with around a mile of the West Beck chalk stream.

This is now known as Skerne Wetlands and in 2014 the Trust completed the purchase of a further 12 hectares of land on the opposite side of the chalk stream to extend the nature reserve to more than 40 hectares and 2.4km (1.5 miles) of chalk stream.

The site complex of more than 80 former fish farm ponds is being developed into a mosaic of wetland habitat to include wet grassland, wet woodland, reedbed and open water. The latest section of the habitat creation, integrating the Copper Hall section of the wetlands into the reserve, completed in early 2018, thanks to a partnership between Yorkshire Wildlife Trust, the Environment Agency, Natural England, East Yorkshire River Trust and Yorkshire Water.
