Afon Dyfrdwy (River Dee) SSSI

The River Dee (Afon Dyfrdwy, Latin: Deva Fluvius) flows through North Wales and Cheshire, England. Most of the river lies in Wales, with the stretch between Aldford and Saltney within England and two other sections forming the border between the two countries. The length of the section from Bala to Chester is 113 km (70 miles). The river rises on Dduallt in Snowdonia and flows east through Llyn Tegid (Bala Lake), Corwen, and Llangollen. It turns north near Overton-on-Dee and forms part of the England–Wales border before fully entering England near Aldford, north-east of Wrexham. It flows through Chester then re-enters Wales near Saltney; the final section is canalised and discharges into the Irish Sea via an estuary 23 km (14 miles) long.

Flows through: United Kingdom.
