Information about the 104km long canalised river Oise and the 34km long Canal latéral à l’Oise

Oise location map France

The river Oise extends 104km from its confluence with the Seine at Conflans-Sainte-Honorine (Fin d’Oise) to the connection with the Canal latéral à l’Oise at Janville (commune of Longueil-Annel). It is extended by the Canal latéral à l’Oise from Janville to connect with the Canal de Saint-Quentin at Chauny, a distance of 34km. The overall route is therefore 138 km long, and forms part of the important waterway route from the Seine to Northern France, Belgium and the Rhine. The Seine-Scheldt waterway is now to be upgraded to European Class Vb dimensions, with locks 185 by 12m, and the new Canal Seine-Nord Europe, which will replace the first the subject of considerable improvement works carried out in the 1960s to make the river navigable by large push-tows. A 2km length of the non-canalised river remains navigable upstream of Janville to serve a boatyard. It should be noted that the kilometre posts along the river are numbered from the upstream end of the Canal latéral à l’Oise. Thus the route description starts at 33.8km.
Junctions are made with the Canal de l’Oise à l’Aisne (PK 3) and with the Canal du Nord (PK 18.6). Forming part of the busy ‘north-south’ route between the Seine basin and northern France and Belgium, the canal has seen large-scale improvement works, like the Oise further downstream. The lower section from the junction with the Canal du Nord is to be further widened or rebuilt on a parallel path as part of the Seine-Nord Europe Canal.

River Oise region map

History – The river was navigated from the Middle Ages, but canalisation started only in 1835, with locks 41 by 6 m or 46 by 8 m. In 1910, a new set of locks 125 by 12 m were built, with limited depth (2.50 m, for a loading draught of 2.20 m). Starting in 1965, after the deeper Canal du Nord was opened, new locks 185 by 12 m were built, with a sill depth of 4m. Dredging in the river was not consistent throughout, and to prepare for the future Seine-Nord Europe Canal, all the weirs are being replaced, and a depth of 3.50 m is to be provided throughout. The canal latéral was built in 1831 to provide a complete itinerary between the Canal de Saint-Quentin and the Seine, and to avoid the winding course of the river Oise in this section. Initially to Becquey dimensions, locks were later doubled and enlarged to 39 by 6 m and 39 by 6.5 m at each fall, with a depth of 2.5m. With the opening of the Canal du Nord, it was decided to further improve the canal downstream of the junction with this new canal. The canal was given 20cm more depth and 5m extra width, and two new locks 100 by 12 m were built around 1970.

Key Waterway Dimensions

  • Max Beam: 6.50m
  • Max Height: 4.10m
  • Max Draught: 2.40m


Navigation This is mostly a grand gabarit waterway that is busy with large commercial peniches and push-tows.

Locks – There are seven locks on the River Oise, each with two large chambers side by side (185 by 12m and 125 by 12m) on a short diversion canal at the level of each weir. All locks are electrically-operated and controlled by lights. At Lock 1 (Venette) boats may be routed to the 125m chamber on the other side of the island ; the lock-keepers have no clear view of this lock, but remote monitoring and control equipment has been installed. The former small locks adjacent to the weirs have been eliminated.

On the Canal latéral à l’Oise, there are four electrically-operated locks. The two downstream of the junction with the Canal du Nord each have two parallel chambers, 125 by 12m and 39 by 6.50m. The two locks above the junction have two chambers of 39 by 6.50m.

Draught The maximum authorised draught is 3.00m from the confluence with the Seine up to Creil (PK 75), 2.50m from Creil to the confluence of the river Aisne, and 2.40m through to the end of the Canal latéral à l’Oise.

Headroom – The headroom under the bridges is at least 5.00m above normal water levels, reduced to 4.10m above the highest navigable water level. The same limit of 4.10 m applies on the lateral canal.

Towpath – There is a good towpath throughout.
