Afon Llwyd

The Afon Lwyd (occasionally mis-spelt as 'Llwyd') is a small river in south Wales which flows from its source north of Blaenavon, through Abersychan, Pontypool and Cwmbran before flowing into the River Usk at Caerleon, which subsequently flows into the Bristol Channel in Newport. The name is Welsh, meaning "Grey River". Historically the river has also been known as the Torfaen. Although this name is no longer in use for the river, it is still in common use as the name for the local authority Torfaen County Borough Council.
