Construction started in 1991 and was completed in 1999. One reason for the construction of the Tishrin Dam was the lower than expected power output of the hydroelectrical power station at the Tabqa Dam. This disappointing performance can be attributed to the lower than expected water flow in the Euphrates as it enters Syria from Turkey. Lack of maintenance may also have been a cause. The Tishrin Dam is the last of three dams that Syria has built on the Euphrates. The other two dams are the Tabqa Dam, finished in 1973, and the Baath Dam, finished in 1986. In the 2000s, Syria had plans to build a fourth dam on the Euphrates between Raqqa and Deir ez-Zor – the Halabiye Dam.
