Garw Valley

The River Garw (Afon Garw in Welsh, meaning "rugged river") runs for about 12 miles from its source in the hills north of Blaengarw to the confluence with the River Ogmore and the River Llynfi at Aberkenfig. It is one of three main tributaries of the River Ogmore which runs through the town of Bridgend. It is in Wales, United Kingdom.

Originating in Blaengarw, it passes through the villages of Pontycymer, Pantygog, Lluest/Braichycymer, Tylagwyn, Llangeinor, Abergarw and finally the village of Brynmenyn, where it joins the River Ogmore.

With most of the River Garw's course running along the floor of the river valley to which its name is given, it collects a number of tributary streams along the way. These streams are listed in order of confluence with the river from its uppermost point to its confluence with the River Ogmore.

The effects of coal mining in the valley, both from small family owned shafts and major pits alike, caused the river to become polluted and dirty with coal dust and other chemicals to the point at which it was once entirely black in colour, earning it the mainly local nickname of the "Black River".

The River Garw once contained Salmon amongst other fish. Industrialisation of the valley resulted in their loss, but they are slowly being re-introduced as part of the valley's regeneration, after the closure of the coal mines in the 1980s and the recovery of the now useful shale through a brief period of restorative opencast mining in the 1990s.
