River Wye boundary, and beyond it at least to Hay on Wye. A horse towing path was added in 1808, but only up to Hereford; previously, as on the River Severn, barges were man-hauled. Money was spent several times improving the River Lugg from Leominster to its confluence with the Wye at Mordiford, but its navigation is likely to have been difficult. The Wye remained commercially navigable until the 1850s, when commercial traffic moved to railways. It is still used by pleasure craft. In 2017 MORE than 600 people took to the River Wye in inflatables ranging from dinghies to paddling pools
River Wye river from Redbrook to Chepstow forms the border between England and Wales. The River Wye forms two Sites of Special Scientific Interest, one covering the Upper Wye ("Gwy Uchaf") above Hay-on-Wye, and one covering the Lower Wye ("Gwy Isaf") downstream to Chepstow. The criteria for inclusion of the river as an SSSI include geology, topography, flora, mammals, invertebrates, fish and birdlife, as the river and its tributaries constitute a large linear ecosystem. The Lower Wye SSSI is itself divided into seven units of assessment set by Natural England, and administrative responsibilities are shared between the county authorities of Powys, Herefordshire,
