Geography

The lake is 155.3 km2.Created by the rise in water levels at the end of the last ice age, this small inland sea is composed of three parts: the principal body of water, the Étang de Vaïne to the east and the Étang de Bolmon to the south-east.

The Étang de Berre is fed with fresh water by the rivers Arc, Touloubre and Cadière and – since 1966 – by the Canal de la Durance. Two canals link it to the sea: the Canal de Caronte leading towards Port-de-Bouc and the Canal du Rove which leads towards L'Estaque. However the underground portion of the latter is blocked by a rock fall.

The Marseille Provence Airport is located in the southeast portion of the Étang Barre, with its main runway extending into the water on reclaimed land.

Ten communes border the Étang de Berre: Istres, Miramas, Saint-Chamas, Berre-l'Étang, Rognac, Vitrolles, Marignane, Châteauneuf-les-Martigues, Martigues and Saint-Mitre-les-Remparts.

History

The ancient name of the Étang de Berre was Stagnum Mastromela, according to Pliny the Elder (Book III [34]).
