List of rivers of Wales

(Redirected from Afon)

Afon redirects here. For Nigerian region, see Imeko Afon

This is a list of rivers of Wales, organised geographically. It is taken anti-clockwise from the Dee Estuary to the M48 Bridge that separates the estuary of the River Wye from the River Severn.

Tributaries are listed down the page in an upstream direction, starting with those closest to the sea. The main stem (or principal) river of a catchment is given, left-bank tributaries are indicated by (L), and right-bank tributaries by (R). Note that, in general usage, the 'left (or right) bank of a river' refers to the left (or right) hand bank as seen when looking downstream. Where a named river is formed by the confluence of two differently named rivers, these are labelled as (Ls) and (Rs) for the left and right forks. A prime example is the formation of the River Taff from the Taf Fawr and the Taf Fechan at Cefn Coed-y-cymmer.

The list includes more or less every watercourse named on Ordnance Survey mapping and thus many of the main rivers of Wales (as defined by Natural Resources Wales ). Difficulties arise otherwise in determining what should and what should not be included.[1]

Certain names are encountered frequently and particular care should be taken to differentiate between the various occurrences of Clydach, Clywedog and of Dulas for example as well as those whose names refer perhaps to the colour of their waters e.g. Afon Goch (red river), Afon Ddu (black/dark river) and Afon Wen (white/light river).

Longest rivers in Wales edit

This is a table of the longest rivers wholly or partially in Wales.[2] Rivers only partly in Wales are included in this table in italics. Note that river lengths given by different authorities vary due to the different ways in which the measurement is made or indeed estimated. That rivers are partly fractal in nature accounts for some variation and lengths can also vary slightly over time as meanders expand or are cut off where rivers run through broad flood-plains.

River Length Notes
(miles) (km)
1 River Severn 220 354 Leaves Wales after 48 miles.
2 River Wye 135 217 Forms the Wales-England border for much of its length.
3 River Teme 81 130 Entirely in England after 12 miles.
4 River Usk 78 126[3] Longest river entirely in Wales according to some sources.[4]
5 River Tywi 75 121
6 River Teifi 73 117 [5]
7 River Dee 70 113
8 River Taff 40 64
