River Ogmore

The River Ogmore (Afon Ogwr in Welsh) is a river in South Wales popular with anglers. It runs generally from north to south from the Ogmore Vale and Pentre, past Bridgend and Ogmore. The river Ogmore is generally considered to start near the cemetery mountain, north of Treorchy, although it is known as the Ogwr Fach, with the Ogwr Fawr, coming from Gilfach to the east merging near Blackmill. The River Llynfi, the River Garw and finally the River Ewenny in its estuary are all tributaries of the Ogmore which flows into the sea between Ogmore-by-Sea and the Merthyr Mawr sand-dunes. Most of the headwaters flow over carboniferous coal measures overlain by glacial drift and fluvial gravels. The valleys are reasonably broad for a small river...
