The River Dyfi north of Machynlleth
|- elevation||1,900 ft (579 m)|

The Dovey rises in the small lake Creiglyn Dyfi at about 1,900 feet (580 m) above sea level, below Aran Fawddwy, flowing south to Dinas Mawddwy and Cemmaes Road, then south west past Machynlleth to Cardigan Bay at Aberdyfi. It shares its watershed with the River Severn and the River Dee before flowing generally south-westwards down to a wide estuary. The only large town on its route is Machynlleth.
Because of its origins high in the Cambrian Mountains and its relatively short length, it is prone to flooding and some roads in the lower catchment can become impassable during very wet weather. It has been a relatively pristine river with few polluting inputs and is notable for its Salmon and Sea Trout (migratory Brown Trout).
The Dovey is joined by the:
- Angell at Aberangell
- Twymyn above Cemmaes Road (Glantwymyn)
- South Dulas above Machynlleth
- North Dulas at Ffridd Gate
- Llyfnant at Glandyfi.
The Dovey Estuary was used as a location shot in Led Zeppelin's 1976 film The Song Remains the Same. The segment of the film is where Robert Plant comes ashore on a boat, after which he rides a horse, making his way to Raglan Castle. Plant was obviously behind the choice of the location, being familiar with the area; Bron-Yr-Aur cottage is located on the edge of Machynlleth.
