The Chamberonne , known in the middle course as Sorge , is an approximately 12 km long tributary of Lake Geneva in the canton of Vaud in Switzerland . It drains a section of the Waadtländer Mittelland and belongs to the catchment area of the Rhone . The area of the Chamberonne catchment area is around 40 km². The name is derived from the Gallic word components cambo- (curve, meander) and onno (river, brook) and therefore means something like meandering brook .
The headwaters of the Chamberonne are located at around 590 m above sea level. M. on the high plateau of the southern part of the Gros de Vaud , west of the municipality of Cheseaux-sur-Lausanne . Over a distance of around 3 km, the two source streams, the Chamberonne and the Petite Chamberonne, flow more or less parallel in valleys that are slightly sunk into the plateau. From the confluence of these two streams in the woods of Plamont and Bois de la Chasse , the river is called Sorge . This moves further south to the Lake Geneva basin, where it crosses the industrial areas of Crissier , Bussigny-près-Lausanne and Ecublens (VD) . Several sections of the concern were covered.
At Ecublens the concern turns to the east and unites with the Mèbre , a creek that flows parallel for long stretches at a distance of 1 km. The last 1 km long section of the river below the confluence of the Sorge and Mèbre rivers is again called Chamberonne . About halfway between Lausanne and Saint-Sulpice (VD) , the Chamberonne flows into Lake Geneva with a small alluvial cone near the former Dorigny mansion .
Most of the time, only the upper reaches of the Chamberonne are in a near-natural to natural state, while the lower reaches have been channeled and partially relocated underground. The Chamberonne has a pluvial discharge regime .
