River Arth
Encyclopedia
The River Arth is a small river
that emerges in the hills near Bethania, Ceredigion
, Wales
, which runs west for 15 miles (24.1 km) and discharges its waters into Cardigan Bay
at Aberarth
.
Despite its small size it is one of the few rivers in Britain which has a bore
when the incoming tide cause a tidal wave to run upstream. The Arth bore is only a few inches high and it runs only for a short distance upstream. Beyond the road bridge in Aberarth, the river rises steeply preventing the bore propagating any further.
In the 1970s, the River Arth suffered severe intermittent agricultural pollution
from a dairy unit not far from the village but improved pollution control and a change of ownership of the farm has rectified that position.
