Karkheh dam has two important characteristics among Iranian dams. The first feature of this dam is that it is the largest barrier of Iranian history and also has the largest artificial lake in the country.

Karkhe dam is located 21 km northwest of Andimashk in Khuzestan province (southwest of Iran). The project is located at 48 degrees and 8.7 minutes east longitude, and 32 degrees and 6.29 minutes north. The purpose of this dam is to provide water for irrigation of 340,000 hectares of downstream land, controlling destructive floods and preventing damages resulting from it, producing hydroelectric power and reducing hydraulic gradients. The type of Karkhe dam is of clay type with a dam height of 127 meters and a crest length of 3030 meters. The dam's width is 12 meters in diameter, followed by 1100 meters. The volume of the reservoir at the operation level of 220 m is 5.6 billion cubic meters (before sedimentation) and the useful volume of the reservoir is 3.9 billion cubic meters (after sedimentation). The water level at the flood event is up to 230.9 and the area of ​​the lake is 220 meters at an operational level of 162.47 square kilometers. The length of the lake is also at an altitude of 220 meters, about 60 kilometers.
