The Ain (in Franco-Provençal: En) is a river in eastern France. It is a right tributary of the Rhône river. It gave its name to the French department of Ain.

Geography[change | change source]

The Ain river has a length of 190 km (118.1 mi), and a drainage basin with an area of 3,765 km2 (1,454 sq mi).[1]

Its average yearly discharge (volume of water which passes through a section of the river per unit of time) is 121 m3/s (4,300 cu ft/s) at Chazey-sur-Ain in the Ain department.[2]

Course[change | change source]

The source of the Ain is a karst spring (a spring that is part of a karst system) in the Jura mountains, between the Conte an the La Favière communes (Jura department), at an altitude of about 680 m (2,231 ft).[3] From here, the Ain flows to the south.

The Ain river flows through 2 regions, 2 departments and 66 communes. It flows through the following communes, among others:[1]

Finally, it flows into the Rhône river in the commune of Saint-Maurice-de-Gourdans, on the border with the Isère department.[4]
