Geography

[edit]

The lagoon covers an area of 155.3 km² (60.0 sq mi). Created by the rise in water levels at the end of theLast Glacial Period (colloquially known as the last ice age), this small inland sea is composed of three parts: the principal body of water, theÉtang de Vaïne to the east and theÉtang de Bolmon to the south-east.

The Étang de Berre is fed withfresh water by the riversArc,Touloubre and Cadière and – since 1966 – byÉlectricité de France'sCanal EDF de la Durance [fr]. Two canals link it to the Mediterranean, the open airCanal de Caronte [fr] leading towardsPort-de-Bouc and theCanal de Marseille au Rhône which leads towardsL'Estaque through theRove Tunnel; the Rove Tunnel has been closed since 1963, after a section of the tunnel collapsed.

TheMarseille Provence Airport is located in the southeast portion of the Étang de Berre, with its main runway extending into the water on reclaimed land.
