geography

course

The headwaters of the Veyron are located at around 720 m above sea level. M. in the Grand Marais corridor at the foot of the Jura on the commune of Bière . On the plateau at the foot of the Jura, the stream flows northeast parallel to the Jura ranges and has only a very slight gradient. At Mollens (VD) , the Veyron enters a boggy valley low with alder forests. This valley with around 500 m wide, flat ground served the Ice Age Rhone glacier as a meltwater channel for a long time.

South of L'Isle , the Veyron turns to the east and overcomes a height difference of 100 meters for 6 km, where it runs in a valley that is sunk about 30 m into the surrounding high plateaus. At the village of La Chaux (Cossonay) , this valley opens into a wide hollow, which is flanked to the east by the ridge of the Bois du Sépey . The stream now flows north-northeast and after a short section in a ravine-like valley it reaches the Tine de Conflens (498 m above sea level), a rock basin in which it flows into the Venoge. Up to this point the Veyron has covered a distance of around 13 km longer than the Venoge; however, the latter generally carries more water.

The entire course of the Veyron has been preserved in a near-natural, partly natural state. From the foot of the Jura , the tributaries Etremble , Malagne , Morand and Gèbre flow to it. The water power of the Veyron has been used in several places for the operation of mills and sawmills since the Middle Ages .
