The Yonne (in French jɔn/) is a river in France, a left-bank tributary of the Seine. It is long. The river gives its name to the Yonne département. It rises in the Nièvre département, in the Morvan hills near Château-Chinon. It flows into the river Seine at Montereau-Fault-Yonne.

The Yonne flows through the following départements and towns:

Château-Chinon, Clamecy

Auxerre, Migennes, Joigny, Villeneuve-sur-Yonne, Sens

Montereau-Fault-Yonne

The main tributaries of the Yonne are the Vanne, the Armançon, the Serein and the Cure.

History

The river was historically used for flottage, or the floating of rafts of timber from the Morvan forest to serve the needs of the capital, Paris.[1] It was bypassed as a rafting waterway by the Canal du Nivernais in 1841, from near its source at Corbigny down to Auxerre.

In 1834 the engineer Charles Poirée had successfully tested his design for a needle weir, and this construction technique was adopted on the river Yonne. The first lock was built in the 1840s, the others from 1861. The locks were enlarged to Freycinet standards in the late 19th century, then again to their current dimensions after World War II.[2]

Navigation

The navigable river Yonne extends for 108km (67miles), from Auxerre (junction with the Canal du Nivernais) to the confluence with the Seine. At Laroche-Migennes (PK 23), the Yonne connects with the Canal de Bourgogne. There are 9 locks on the river on the first section to Laroche-Migennes, the remaining 17 on the more gently-sloping lower course of the river.
