. The former British Mandate administrators (Iraq became independent in 1932) were the first to attempt to drain the marshes, motivated by their role as a breeding ground for mosquitoes and lack of apparent economic value, as well as the potential use of the water for irrigation. Prepared in 1951, The Haigh Report outlined a series of sluices, embankments and canals on the lower ends of the Tigris and Euphrates that would drain water for agriculture. These notably included the Main Outfall Drain (MOD), a large canal also referred to as the Third River, and the Nasiriyah Drainage Pump Station. Neither were completed under British rule: they were later revived by the

, many embankments and drainage works were dismantled under the newly formed administration, and the marshes began to refill. Some of this dismantling was done by local Marsh Arabs acting on their own.

There was flooding in southern areas which had previously been dry since the early 1990s.Iraq Marshlands Restoration Program

There has been some corresponding recolonization by the natural marsh vegetation since that time, and return of some species of fish and birds.

By 2008, 75% of the marshes had been restored, including most of the Central Marshes. However, the wetlands have since shrunk to 58% of their pre-drainage area and are projected to drop below 50% as a result of Turkish and Iranian damming of the Tigris and Euphrates, which the UN reports has reduced the combined volume of the rivers by 60%. Further, the water quality and salinity is much worse than in the pre-drained marshes: water salinity has soared to 15,000 parts per million (ppm) in some areas, up from 300 to 500 ppm in the 1980s. This increased salinity has hindered the reintroduction of native plant and fish species and has had major detrimental effects on buffalo herding and fishing in the marshes, the chief economic activities of the Marsh Arabs. 2010 research in the Central Marshes attributed the increased salinity and decreased water quality to the limitation of the water source to only the Euphrates, a smaller seasonal fluctuation in water inflow and outflow, and inputs of
