Infrastructure
- The locks: the canal originally had 56 locks to which 4 locks were added to make the connection with the River Garonne at Castets-en-Dorthe.
- The Montech water slope: this structure came into service in 1974, the brainchild of the engineer Jean Aubert. The slope allows a flight of five locks to be bypassed by large vessels (only) but is currently (2010) out of commission.
- The Aqueducts: seven aqueducts allow the canal to cross the River Garonne and its tributaries, such as that over the River Baïse. The most significant two are the Agen aqueduct, 600 metres long with 23 arches and the Cacor Aqueduct at Moissac over the River Tarn, 356 metres long with 13 arches.
- A lock at Moissac allows a connection to the lowest section of the Tarn and a small part of the Garonne.
- The Canal de Montech, also known as the Montauban Branch, provides a connection from the main line of the Canal de Garonne, at Montech, with the Tarn higher upstream at Montauban. A proposal exists to create a waterway ring by restoring navigation to the stretch of the Tarn between Moissac and Montauban.
