In its northerly course it is regularly fed by the Yonne and on the southern slope by the Aron. The summit level pound also comprises three tunnels. Although the feeder canal arrives at Port Brûlé, the top of the canal is generally considered to be at Baye at the southern end of the tunnels.

Construction of the canal began in 1784, initially to aid the flottage (floating) of timber rafts from the forests of the Morvan national park to Paris, via Clamecy and Auxerre. However, in reality, the canal was quickly established as an important communication route, carrying timber, building stone, grain and wine out of the region, and bringing in coal. It contributed significantly to the economic development of the Nièvre, particularly the area known as the 'Valleys of the Yonne' of which the small town of Clamecy is the capital, and also to the quarries at Chevroches and Dornecy. The canal du Nivernais importance in this respect, faded with the arrival of the railway in the 19th century.
