It is a restricted lagoon of 115 km2 (25 by 7.5 km) and with a depth not exceeding 8m.The island barrier is 25 km large with an average width of 300-400m (it can come up to 2 km in some parts) and is cut by an artificial inlet. The lagoon is nourished by several tributaries which are used today for the sewer discharge of the upstream built-up areas. There are 3 urban clusters in the surroundings and 2 saline workings on the banks of the lagoon. There is also an important fish farm.
