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.

History

The canalisation works were carried out by order of Napoleon in 1802 to provide access to the strategic military town of Pontivy. Like the entire Brittany canal network, its ''raison d’être'' was military defence in case of a naval blockade of the coast by the British Navy. Works began in 1804 and were completed in 1825.

Navigation

The waterway has little recreational traffic because of the large number of locks in the watershed section of the Nantes-Brest canal between Pontivy and Rohan, and the effective barrier of Guerlédan Dam to the west.
