Samarra Barrage

Samarra Barrage (Arabic: سد سامَرّاء‎) and Thar Thar Barrage (Arabic: سد الثَرثار‎) is a multi-purpose barrage on the Tigris River adjacent (west) of Samarra and north of Baghdad, Iraq. The main purpose of the dam is to divert floodwater in the Tigris River to Lake Tharthar through the Thar Thar depression along with irrigation and a 84 MW hydro-electricity station. It also serves to produce hydroelectric power and flood control – although the later has become less critical with the construction of the Mosul Dam upstream and several other large dams in Turkey.
