The Allier is a river in France. It rises in the Lozère department in the Cevennes , on the southern flank of the Moure de la Gardille summit , in the municipality of Chasseradès .


The Allier forms the border between the Lozère and Ardèche departments , drains generally northwards and flows into the Loire after 421 km at Bec d'Allier , in the municipality of Cuffy in the Cher department , as a left tributary .

The Allier department is named after the Allier ; other departments through which it flows are Lozère , Ardèche , Haute-Loire , Puy-de-Dôme , Nièvre and Cher .


The Allier receives additional water through the Naussac dam and therefore also has more water in its bed than it would be natural, since streams that otherwise drained differently are diverted into the Allier to generate electricity. Immediately before the confluence, the Loire Lateral Canal ( Canal latéral à la Loire ) crosses the Allier with the imposing canal bridge Le Guétin .


In the early 1990s, many weirs were removed or modified; since then, salmon have again been able to migrate unhindered to the upper reaches of the spawning area. Special protection times and zones support this.


On the border between the Lozère and Haute-Loire departments are the Gorges de l'Allier , which can be visited by excursion train between Langogne and Langeac . The Allier is also very popular with canoeists - from Langogne to Langeac for whitewater paddlers, from Langeac to the Loire for touring paddlers (the part from Pont d'Alleyras to Monistrol, however, is closed to paddlers).
