The Haditha Dam (Arabic: سد حديثة‎) or Qadisiya Dam is an earth-fill dam on the Euphrates, north of Haditha (Iraq), creating Lake Qadisiyah (Arabic: Buhayrat al-Qadisiyyah‎). The dam is just over 9 kilometres (5.6 mi) long and 57 metres (187 ft) high. The purpose of the dam is to generate hydroelectricity, regulate the flow of the Euphrates and provide water for irrigation.
