. The barrage consists of two separate parts. The main stretch of the barrage has ten gates measuring 16 by 8.5 m (52.5 by 27.9 ft), allowing a maximum discharge of 3600 cubic metres (127,132.8 cu ft) per second. The second part on the left bank of the river has eight gates that are 6 metres (19.7 ft) wide. These gates divert water toward two separate irrigation channels. Their maximum discharge is 104 cubic metres (3,672.7 cu ft) per second.

The construction of the Fallujah Barrage was first proposed in 1923 as part of a large project to increase the production of cotton

in Iraq. Construction of the barrage did however start only much later. The barrage was constructed adjacent to the actual Euphrates channel so that the water did not have to be diverted during construction. The Euphrates flow was only diverted toward the barrage in 1985 when it was completed. It was intended that 225000 hectares (555,986.6 acre) would be irrigated as part of this project. After the 2003 invasion in Iraq, repairs have been carried out at the Fallujah Barrage.
