The Dee Estuary (Welsh: Aber Dyfrdwy) is a large estuary by means of which the River Dee flows into Liverpool Bay. The estuary starts near Shotton after a five miles (8 km) ‘canalised’ section and the river soon swells to be several miles wide forming the boundary between the Wirral Peninsula in north-west England and Flintshire in north-east Wales.
