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 Gilfach Goch, past Bridgend and Ogmore. The River Ogmore rises at Craig Ogwr (527m) in the Ogmore Valley as the Ogwr Fawr before linking with the Ogwr Fach at 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.

Geology and geography

The Ogmore has two major branches in its headwaters; the Ogwr Fawr which flows south through Nantymoel, Ogmore Vale and Lewistown and joining it from the east the Ogwf Fach which flows through Gilfach Goch and, after the confluence with the Nant Iechyd, they join to form the Afon Owr at Blackmill

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 and many of the tributaries meandered through their valleys in the past. The considerable urbanisation, especially in the 19th century confined most rivers to rather narrow artificial channels bordered in places such as Bridgend with concrete flood protection walls.

Ogwr

The Borough of Ogwr was one of six districts of Mid Glamorgan in Wales, which existed from 1974 to 1996.

It was formed under the Local Government Act 1972 from the urban districts of Bridgend, Maesteg, Ogmore and Garw and Porthcawl, along with Penybont Rural District from the administrative county of Glamorgan. In 1996 most of Ogwr became part of Bridgend County Borough, with the Vale of Glamorgan taking the communities of Wick, St Brides Major and Ewenny.

The district took its name from the local River Ogwr.
