    Mosul Dam is an earthfill multipurpose dam. It is located on the River Tigris in northwestern Iraq. The dam is 3.65 km long and its crest elevation is at 341 m above sea level. The storage capacity at normal operation level (330 m above sea level) is 11.11km3. The work to build the dam started on 25th January, 1981 and finished on 24thJuly, 1986. The total cost of the development was estimated at 2.6 billion US$. The foundation of the dam lies on the Fatha Formation.
