The Kut Barrage is a barrage on the Tigris river, located in the modern town of Kut in Wasit Governorate, Iraq. It is 516 metres (1,693 ft) long, 10.5 metres (34 ft) high and consists of 56 gates, each 6 metres (20 ft) wide. The maximum discharge of the barrage is 6,000 cubic metres (7,800 cu yd), but actual discharge has not exceeded 2,000 cubic metres (2,600 cu yd) in the last 10 years. The barrage supports a road and includes a lock for boats passing up and down the Tigris. Its purpose is to maintain a sufficiently high water level in the Tigris to provide water for the Gharraf irrigation canal, which branches off the Tigris just upstream from the Kut Barrage. Before the construction of the Kut Barrage, the Gharraf canal only received water during periods of flood in the Tigris.
