Camddwr
The Camddwr is a significant right-bank tributary of the River Towy in the eastern part of Ceredigion, mid Wales. It rises on the undulating plateau east of Garn Gron and flows in a generally south-southeasterly direction into Llyn Brianne, a reservoir formed by the damming of the upper Towy, A chapel at Soar y mynydd beside the river is often mentioned as being the most isolated in Wales.
