Characteristics
The Hammar Marshes stretched between Nasiriyah and Basra and were located south of the Euphrates River, which formed their principal source. Their main feature was the large brackish lake Haur al-Hammar, the largest water body in the lower Euphrates. Additional water from the Tigris reached the system through overflow from the Central Marshes.
With a wide variety of habitats, the Hammar Marshes and the Haur al-Hammar supported large populations of birds, notably pelicans and ducks, with the Haur Aluwez in the south-east being especially significant for these species.
The area was formerly populated by the Marsh Arabs or Ma'dan.
