The Rhône is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and southeastern France before discharging into the Mediterranean Sea. At Arles, near its mouth, the river divides into the Great Rhône and the Little Rhône. The resulting delta forms the Camargue region.
The Saône is a river in eastern France. It is a right tributary of the Rhône, rising at Vioménil in the Vosges department and joining the Rhône in Lyon, at the southern end of the Presqu'île.
The Moselle is a river that rises in the Vosges mountains and flows through north-eastern France and Luxembourg to western Germany. It is a left bank tributary of the Rhine, which it joins at Koblenz. A small part of Belgium is in its basin as it includes the Sauer and the Our.
The Canal de la Sambre à l'Oise is a canal in northern France. It forms a connection between the canalised river Sambre at Landrecies and the Oise at La Fère. The canal is 71 kilometres (44 mi) long, and has 38 locks. The junction made at La Fère is with a branch of the Canal de Saint-Quentin, while the Canal latéral à l'Oise is joined 10.5 km further downstream at Chauny. It was used by the standard Freycinet-gauge péniches, 38.50 metres (126.3 ft) long, and 5.05 metres (16.6 ft) in beam, carrying up to 250 tonnes. The canal, also a popular waterway for boats heading south from the Netherlands and Belgium to the central French waterways, had to be closed in 2006 when two aqueducts were found to be in danger of failing. Funding has been put in place by the owner, Voies Navigables de France, and the local authorities, with support from the State. The canal was reopened in July 2021.
The Marne is a river in France, an eastern tributary of the Seine in the area east and southeast of Paris. It is 514 kilometres (319 mi) long. The river gave its name to the departments of Haute-Marne, Marne, Seine-et-Marne, and Val-de-Marne.
The Sambre is a river in northern France and in Wallonia, Belgium. It is a left-bank tributary of the Meuse, which it joins in the Wallonian capital Namur.
The Aisne is a river in northeastern France. It is a left tributary of the Oise. It gave its name to the French department of Aisne. It was known in the Roman period as Axona.
The Blavet river flows from central Brittany and enters the Atlantic Ocean on the south coast near Lorient. It is 148.9 km (92.5 mi) long. The river is canalised for most of its length, forming one of the links in the Brittany canal system. It connects with the Canal de Nantes à Brest at Pontivy and runs to Hennebont, a distance of 60 km. From the last lock at Polvern, the river is tidal and considered as a maritime waterway, giving access to the seaport of Lorient and the Atlantic Ocean. It became more important when the western half of that system was cut off by the construction of the Guerlédan dam and hydropower plant. Today, boats coming from Nantes via Redon have to take the Canal du Blavet in order to reach the ocean near Lorient.
The Nantes–Brest canal is a French canal which links the two seaports of Nantes and Brest through inland Brittany. It was built in the early 19th century, and its total length as built was 385 km with 238 locks.
The Canal de la Marne au Rhin is a canal in north-eastern France. It connects the river Marne and the Canal entre Champagne et Bourgogne in Vitry-le-François with the port of Strasbourg on the Rhine. The original objective of the canal was to connect Paris and the north of France with Alsace and Lorraine, the Rhine, and Germany. The 313 km (194 mi) long canal was the longest in France when it opened in 1853.
The Canal du Centre, originally known as the Canal du Charollais, is a French canal running from Digoin, where it now joins the Canal latéral à la Loire, to the Saône at Chalon-sur-Saône. It was opened in 1792 and was the first watershed canal allowing boats to pass from the north of France to the south. It is 112.1 kilometres (69.7 mi) long and has 61 locks. Most of its traffic was generated by now abandoned coal mines at Montceau-les-Mines.
The Canal du Nord is a 95-kilometre (59 mi) long canal in northern France. The canal connects the Canal latéral à l'Oise at Pont-l'Évêque to the Sensée Canal at Arleux. The French government, in partnership with coal-mining companies in the Nord and Pas-de-Calais departments, developed the canal to help French coal mining companies withstand foreign competition. Construction of the canal began in 1908 but halted in 1914, because of the First World War. The war caused widespread destruction of the canal and the French government made no attempt to resume construction until 1959. Construction recommenced in 1960 and the waterway opened to the public in 1965. The Canal du Nord and the Canal de Saint-Quentin may be supplanted by the Seine–Nord Europe Canal, a projected high capacity link between the Oise River at Janville and the high capacity Dunkirk-Escaut Canal.
The Canal du Rhône au Rhin is one of the important watershed canals of the French waterways, connecting the Rhine to the Saône and the Rhône and thereby the North Sea and the Mediterranean. As built, the canal was made up of four distinct sections:
The Canal du Loing is a 49.4 km long canal which connects the Seine at Saint-Mammès to the Briare Canal just north of Montargis, in central France. It runs through the Loiret and Seine-et-Marne départements.
The Canal latéral à l'Aisne is a canal in northern France, which connects the Canal des Ardennes at Vieux-lès-Asfeld to the canalised river Aisne at Condé-sur-Aisne. It is 51.3 km (31.9 mi) long, with 8 locks. It runs alongside the Aisne. It has junctions with the Canal de l'Aisne à la Marne at Berry-au-Bac and with the Canal de l'Oise à l'Aisne in Bourg-et-Comin.
The Canal de l’Aisne à la Marne is a canal in northeastern France which connects the Aisne and the Marne valleys. It runs from the Canal latéral à l'Aisne at Berry-au-Bac to Condé-sur-Marne on the Canal latéral à la Marne, a distance of 58 km. The canal rises 40m through 16 locks via the cathedral city of Reims, which is also a busy commercial port, to a summit level at an altitude of 95.70m. After crossing the watershed through a tunnel 2302m long at Mont-de-Billy, the canal drops down 23.80m through a flight of 8 locks towards the Marne.
The Oudon is a 103.2 km (64.1 mi) long river in the Mayenne and Maine-et-Loire départements, western France. Its source is near La Gravelle. It flows generally south east. It is a right tributary of the Mayenne into which it flows between Le Lion-d'Angers and Grez-Neuville.
The Canal latéral à l'Oise is a canal in northern France that, along with the river Oise, connects the Canal de Saint-Quentin at Chauny to the Seine at Conflans-Sainte-Honorine. See under the river Oise for the continuation of the route; the junction is made downstream of the lock at Janville 49.45750°N 2.85933°E. When a canal is latéral, it follows the course of the river it is named after but in a separate excavated channel. The route described below is the 34 km of canal parallel to the river Oise and 103.5 km of the canalised river Oise.
The Canal entre Champagne et Bourgogne, previously named Canal de la Marne à la Saône, is a canal in north-eastern France connecting the towns of Vitry-le-François and Maxilly-sur-Saône. It is a summit level canal of Freycinet dimensions connecting the Marne and the Saône. It is 224.191 kilometres long, and has 114 locks and two tunnels, Condes which is 275 metres long and the tunnel on the summit level between Balesmes-sur-Marne and Noidant-Chatenoy, 4820 metres long. which runs almost exactly underneath the source of the Marne.
The Canal de la Sarre, originally called Canal des Houillères de la Sarre, connects the Canal de la Marne au Rhin in Gondrexange to the canalised river Sarre in Sarreguemines in northeastern France. For convenience this entry covers the entire waterway in France, including the canalised river. The canal is 63 km long, and the French portion of the canalised river Sarre is 12 km long, making a total of 75 km, with respectively 28 and 2 locks.
