The Buron is a 17 km long southern tributary of Lake Neuchâtel in the canton of Vaud in Switzerland . It drains a section of the Waadtländer Mittelland and belongs to the catchment area of ​​the Rhine .

geography

course

The source area of ​​the Buron lies at around 650 m above sea level. M. in the forest area Grand Bois in the municipality of Goumoens-la-Ville north of Echallens on the plateau of the Gros de Vaud . Several spring streams gather at 600 m above sea level. M. in a wide valley between two ridges of the Gros de Vaud high plateau reaching north. The Buron flows north, initially in an open valley, flanked by the ridge of the Bois de Suchy in the west and the Grand Bois d'Essertines in the east. North of the hamlet of La Robellaz , it gradually deepens into the molasse layers and forms a wooded valley with numerous short meanders .

At Gressy , the most important side stream flows from the right, the Niauque . Shortly afterwards the Buron enters the agriculturally intensively used Orbe plain and now flows further north along its eastern edge. As a canal, it crosses the settlement area of Yverdon-les-Bains before flowing into Lake Neuchâtel east of the Zihl Canal and the Canal Oriental .
