The Canal de la Somme is a canal in northern France. Its total length is 156.4 km with 25 locks, from the English Channel at Saint-Valéry-sur-Somme to the Canal de Saint-Quentin at Saint-Simon.


The Somme River was canalized beginning in 1770. The 54 km section from St. Simon to Bray was completed by 1772, but the rest was not finished until 1843.[1]


The canal as originally built has seen substantial modifications since construction of the Canal du Nord in 1904-1965, and is now made up of four distinct sections:

Some authors distinguish the Grande Somme downstream from Péronne and the Petite Somme upstream from Voyennes. Since 2005 the latter section has been closed to navigation as a result of silt deposits.[1]

In the 1960s, more than 300,000 tonnes of goods were transported on the canal. Today it is used largely by pleasure boats.
