course
The river has its source at a height of 280 meters near the hamlet of La Noche in the municipality of Piégut-Pluviers. Its initial direction of flow is to the southwest, forming the border between the communes of Piégut-Pluviers and Augignac and then between Saint-Estèphe and Augignac. After 5 kilometers, it is dammed near Saint-Estèphe to form the 30-hectare Grand-Étang , a popular swimming lake with a campsite. Immediately down the valley, it crosses the sea of rocks of the Chapelet du Diable with the Roc Branlant . It then changes course at Le Briodet and flows west. At Pinard (municipality of Le Bourdeix) it takes up the Ruisseau des Forges as a right tributary and changes its direction of flow again to the southwest. Before it flows into the Bandiat, it comes towards the left branch of the Combas at the mill Le Moulin de chez Jouannaud . The confluence with the Bandiat is about 1 km southeast of Javerlhac at an altitude of 120 meters.
geology
The Doue drains most of the Piégut-Pluviers-Granodiorit . Only when it reaches the municipal area of Javerlhac-et-la-Chapelle-Saint-Robert at the Le Moulin Vieux mill (about 2 kilometers from the mouth) does it flow through the shallow sediments of the Aquitaine basin , consisting of lias ( Pliensbachium and Toarcium ) and limestone des Doggers ( Bathonium , partly also recrystallized here). It flows into the Pleistocene alluvium of the Bandiat valley.
