Navigation
The Tarn was once navigable from its junction with the Garonne to Corbarieu, near Montauban. This stretch of river included seven river locks over a distance of 38 kilometres (24 mi). The canal was linked to the Canal de Garonne in Moissac by a branch lock upstream of the first river lock, and again, via the Canal de Montech, at Montauban.
The two access points from the Canal de Garonne have both been restored, and boats can again access the immediate reaches of the river at these points. Additionally the first river lock, between Moissac and the Garonne itself, has been flooded by the barrage for the Golfech power station on the Garonne, and is permanently open to boats which can thus reach the Garonne and navigate a short distance of that river.
The remaining six river locks are disused and unnavigable. A proposal exists to restore the five river locks between Moissac and Montauban, thus creating a waterway ring consisting of the Tarn from Moissac to Montauban, the Canal de Montech to Montech and the Canal de Garonne back to Moissac.
