Explanations for the table:

• If in a line the indication of the confluence side (“right” / “left”) has been moved under the name box of a line above, the body of water shown in the bottom line flows into the one shown in the above line.
• If a tributary of a higher ranking river is listed in the line under an inflow of a tributary, the associated page number is accordingly further up under the beginning of the name box of the higher-ranking river.

shipping

Garonne and its side canal in Meilhan

The Garonne is navigable from its mouth to the Pont de Pierre in Bordeaux for seagoing vessels, for which the height of 53 meters of the Pont d'Aquitaine and the 2.8 kilometers upstream lift bridge Pont Jacques Chaban-Delmas is sufficient. After that, the arch height of the Pont de Pierre and the respective water level of the Garonne limit shipping to inland vessels , such as the Péniches , which can sail on the Garonne to Langon or to the town of Castets-en-Dorthe . Because shipping further upriver used to be dependent on the changeable water flow , the Garonne Lateral Canal was built, which runs parallel to the river to Toulouse and continues to the Mediterranean in the Canal du Midi . Today, however, it is almost exclusively used for tourist purposes.

Between the towns of Saint-Léger (on the left bank) and Nicole (on the right bank), ships that want to reach the river Lot or come from it are also allowed to sail on the Garonne, depending on the water level .
