River Dyfi

The River Dyfi (Welsh: Afon Dyfi Welsh pronunciation: [ˈdəviː], sometimes anglicised as River Dovey /ˈdʌviː/,) is a river in Mid Wales. It is approximately 30 miles (48 km) long.[1] Its estuary forms the border between the counties of Gwynedd and Ceredigion, and its lower reaches have historically been considered the boundary between North and South Wales.[2][3]

Name

Nowadays the Welsh spelling Dyfi is widely used locally and by the Welsh Government,[4] Natural Resources Wales[5] and the BBC.[6] The anglicised spelling Dovey continues to be used by some entities.[7][8][9][10][11]

Sources

The River Dyfi rises in the small lake Creiglyn Dyfi at about 1,900 feet (580 m) above sea level, below Aran Fawddwy,[12] flowing south to Dinas Mawddwy and Cemmaes Road (Welsh: Glantwymyn), then south west past Machynlleth to Cardigan Bay (Welsh: Bae Ceredigion) at Aberdyfi. It shares its watershed with the River Severn (Welsh: Afon Hafren) and the River Dee (Welsh: Afon Dyfrdwy)[13] 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).[14]

The catchment area is notable for its now-defunct lead mines and slate quarries, especially around Corris and Dinas Mawddwy.

Tributaries

The main tributaries of the River Dyfi are:

Dyfi Bridge
Main article: Dyfi Bridge

The road bridge which crosses the river north of Machynlleth is a landmark.[15]

Dyfi Biosphere

The area around Aberystwyth and the Dyfi Valley is known as the Dyfi Biosphere (Welsh: Biosffer Dyfi). It was UNESCO-designated in 1978.[16][17] Within the biosphere are a number of Special Areas of Conservation and Sites of Special Scientific Interest (Cors Fochno, Coed Cwm Einion and Pen Llŷn a’r Sarnau).

Film Location

The Dyfi 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.

gollark: Was it just a really gold-rich area for some reason?
gollark: How do you even *get* pure gold from arbitrary ground locations, in significant quantities?
gollark: The *true* form of cereal bars was of course covered up by the lace person.
gollark: It could very much *not* be perceived that way, in a world where culture came out differently.
gollark: It's only that way because it's perceived that way because ???.
