River Dovey
The River Dovey or River Dyfi flows through the counties of Merionethshire and Montgomeryshire and its broad estuary forms the border between Merionethshire and Cardiganshire.
Course
The Dovey rises in Merionethshire, high in the Cambrian Mountains in the small lake named Creiglyn Dyfi at about 1,900 feet above sea level, below Aran Fawddwy.
From the mountain, the river flows south to Dinas Mawddwy and down through great fields entering Montgomeryshire where it collects the waters of the River Angell at Aberangell. It continues south to Cemmaes Road, and southwest past Machynlleth, where it collects the waters of the River South Dulas from the south and then the River North Dulas from the north, assuming thereafter the latter's office of boundary river beyween Montgomeryshire and Merionethshire.
Just a few miles below Machynlleth the Dovey becomes tidal.
The lowest bridge on the river is the railway bridge by Dovey Junction station, a few yards below which the river leaves Montgomeryshire behind; the estuary opens up and becomes a great sea-loch parting Merioneth from Cardiganshire, opening finally into Cardigan Bay at Aberdyfi.
The only large town on the Dovey is Machynlleth in Montgomeryshire.
Because of its source high in the Cambrian Mountains and its relatively short length, the Dovey is prone to flooding and some roads in the lower catchment can become impassable during very wet weather. It is a very clean river with little pollution befouling its waters and is rich in salmon and sea trout, which latter are migratory brown trout).
The catchment area was notable for its now defunct lead mines and slate quarries, especially around Corris and Dinas Mawddwy.
Tributaries
Amongst the tributaries of the Dyfi are:
- The Angell at Aberangell
- The Twymyn]] above Cemmaes Road
- The South Dulas above Machynlleth
- The North Dulas at Ffridd Gate
- The Llyfnant at Glandyfi.
