Afon Dringarth
Encyclopedia
The Afon Dringarth is a river in Powys
, Wales
and wholly contained within the Brecon Beacons National Park. Its headwater streams drain the eastern slopes of Fan Dringarth, the southern slopes of Craig Cerrig-gleisiad
and the western slopes of Fan Fawr
. The river flows south-southwest for about 6km / 3.5mi to its confluence with the Afon Llia
one mile north of the village of Ystradfellte
, continuing south as the Afon Mellte. The river may derive its name from the hill immediately to its west, Fan Dringarth.
The Afon Dringarth flows across ground formed from the Old Red Sandstone
laid down during the Devonian period. The presence of areas of glacial till reveals that the area was inundated by ice during the ice ages. The waters of the river were impounded by a dam during the early 20th century to form Ystradfellte Reservoir
