Geography

The Truyère river has a length of 167.2 km (103.9 mi) and a drainage basin with an area of 5,507 km2 (2,126 sq mi).[1]

Its average yearly discharge (volume of water which passes through a section of the river per unit of time) is 69.5 cubic metres per second at Entraygues-sur-Truyèret.[2]

Course

The Truyère starts in the Margeride mountains, south-western Massif Central, north of Mende, in the "commune" of La Villedieu (Lozère department), at an altitude of about 1,460 m (4,790 ft).[3]

The Truyère flows to the west, in general, and passes through 2 regions, 3 departments and 44 communes:[1]

  • Occitanie region
    • Lozère: Le Malzieu-Ville, Chaulhac, Saint-Léger-du-Malzieu, Rimeize, Blavignac, Saint-Pierre-le-Vieux, Fontans, Saint-Gal, Serverette
  • Auvergne-Rhône-Alpes region
    • Cantal: Saint-Martial, Chaliers, Oradour, Fridefont, Alleuze, Faverolles, Neuvéglise
  • Occitanie region
    • Aveyron: Entraygues-sur-Truyère, Thérondels, Cantoin, Montézic, Brommat

Finally, it flows, as a right tributary, into the Lot river, in Entraygues-sur-Truyèret, in the Aveyron department, at 228 m (748 ft) of altitude.[4]

The Garabit Viaduct is a bridge over the Truyère near Ruynes-en-Margeride that was built by Gustave Eiffel.

There are several dams over the river to produce hydroelectricity.
