River Gwenfro


The River Gwenfro is a small river in Wrexham County Borough, north Wales. It is a tributary of the Clywedog. The name Gwenfro is possibly derived from the Welsh language words gwen, "white", and bro, "border", "boundary".
The river rises at a number of small springs south and east of the village of Bwlchgwyn, including a place called Ffynnon y Ceirw. It flows eastwards for several miles through a rather deep valley, and is joined by several other streams; it then passes through Wrexham town centre, where it is largely culverted, and joins the Clywedog at King's Mills.
The Gwenfro was an important water source for Wrexham industry and has had pollution issues. Although still periodically affected – an incident in 2006 led to a fine for Welsh Water – fish including brown trout and roach are now present.
