History
The Venoge was called Venobia in 814, Venubia in 937, Vinogia in 7th century, Venopia in 1313 and Venogy in 1316. Its name is probably of Celtic origin.

In 1913 it was described as splitting at La Sarraz, with the smaller part joining to the Mozon, which flows into Lake Neuchâtel at Yverdon-les-Bains, and the main part turning to the south and flowing into Lake Geneva east of Morges.

The river has been subject to heavy pollution during the 20th century. The building of more and better sewage plants along its course has led to an improvement since 1990.
