The River Dee (Welsh: Afon Dyfrdwy, Latin: Deva Fluvius) is a river flowing through North Wales, and through Cheshire, England, in Great Britain. The length of the main section from Bala to Chester is 113 km (70 miles) and it is largely located in Wales. The stretch between Aldford and Chester is within England, and two other sections form the border between the two countries.[1]

The river rises on Dduallt in Snowdonia and flows east through Bala Lake, Corwen, and Llangollen. It turns north near Overton-on-Dee and forms part of the England–Wales border before fully entering England north-east of Wrexham. It flows through Chester then re-enters Wales; the final section is canalised and discharges to the Irish Sea via an estuary 23 km (14 miles) long.
