The Karkheh Dam () is a large multi-purpose earthen embankment dam built in Iran on the Karkheh River in 2001 by the contractor of Khatam al-Anbiya Construction Central Headquarters of the Islamic Revolutionary Guards Corps (IRGC).

The dam is in the northwestern province of Khūzestān, the closest city being Andimeshk to the east. It is 127 m high and has a reservoir capacity of 5.9 billion cubic meters. The Karkheh Dam is designed to irrigate 320,000 ha of land, produce 520 MW of hydro-electricity and prevent downstream floods.

Mean annual electricity generation is approximately 700 GWh. Based on IWPCO records, dam's power plant generated total of 4,941 GWh electricity during 2002–2008. In 2014 the maximum water in the reservoir of the dam reached 1,900,000,000 m3 and it is estimated that this number will be even less in 2015.

Hawizeh Marshes is affected by the torrential sediments of rivers such as Tigris and Euphrates in Iraq and Karkheh in Iran. Karkheh dam caused to decline the quantity of entering water to the wetland and following it, the wetland extend has been reduced remarkably.

Construction

In 1956, studies began on the Karkheh Dam by the American company Development and Resources Corporation, which was headed by David E. Lilienthal, the former chairman of the Tennessee Valley Authority (TVA). In 1990, the final studies and design were completed by Mahab Ghodss Consulting Engineers, directed by master engineer Mohammad Soleymani. The engineering division of the Islamic Revolutionary Guards Corps (IRGC) started construction on the Karkheh Dam in 1992 and the dam was complete in 2001.
