What is "chavanon"

The Chavanon (also called la Ramade) is a long river in the Creuse, Puy-de-Dôme and Corrèze départements, central France. Its source is in Crocq. It flows generally southeast. It is a right tributary of the Dordogne into which it flows between Savennes and Confolent-Port-Dieu.

On most of its course it forms part of the boundary between the Limousin and Auvergne regions.
