Author 'Fifie34' (Id 101992 ) : What is the empty channel of water? Canal is the junction between the Canal du Midi and the Aude. With a length of 5km, this waterway has been commissioned at the end of the eighteenth or hundred years after the Canal du Midi, connecting it to the Aude and the Canal de la Robine towards Narbonne and Port la Nouvelle. We see the water off, probably for maintenance issues. It's main feature is to be lined with pine trees rather than plane as is usually the banks of the Canal Riquet.
