The Tishrin Dam is a dam on the Euphrates river, located 90 kilometres (56 mi) east of Aleppo in Aleppo Governorate, Syria. The dam is 40 metres (130 ft) high, and has 6 water turbines capable of producing 630 MW. Construction took place between 1991 and 1999. Rescue excavations in the area that would be flooded by the dam's reservoir have provided important information on ancient settlement in the area from the Pre-Pottery Neolithic A (PPNA) period onward.
