Monne

The river is 27.9 kilometres (17.3 mi) long.^[1] The Monne is part of a hydrographical whole, draining les monts Dore. The system is made up of rivers flowing eastward into the river Allier in the plains of the Limagne. To the south lies le pays des Couzes with, from south: la Couze d'Ardes, la Couze Pavin and la Couze Chambon; beyond flows la Monne and the Veyre. Continuing north one finds other rivers feeding from la chaîne des Domes : l'Auzon, l'Artière and la Tiretaine which flows through Royat and Clermont-Ferrand.

All rivers descending more than 1,000 metres (3,300 ft) down to about 350 metres (1,150 ft) etch the granitic ridge of la faille des Limagnes +/- deeply from west to east. The most wild and spectacular gorges are those of la Monne located between Olloix and Cournols.
