River Garw - Flood Risks

Flood Risks

During periods of prolonged heavy rain, the River Garw quite commonly bursts its shallow banks, causing minor flooding in all villages along its length. As the villages are mostly up on the valley sides, this doesn't have any significant effect, save for a few places; a house that once stood next to what is now a small footbridge across the river near the children's playground on the valley floor at Pantygog was demolished some years ago due to constant flooding from the river. The river has also been known to flood the playground area at Braichycymmer, and sometimes becomes hazardous near the Llangeinor playing fields/railway crossing, and in the lower regions of Bryngarw Country Park (where it has become less of a problem due to the deepening off the river bed to these ends). Its tributary streams, one of which joins at the boundary of Pontycymer and Pantygog, can turn from mere babbling brooks to raging torrents in a matter of a few minutes, and it is not unknown for this to occur very suddenly.
