Background:
The Tabqa Dam is largest dam in Syria and its located on the Euphrates river, 40 kilometers West from city of Raqqa in Raqqa Governorate.
Nearest city to the dam is Al-Tabqa and its located South of the dam itself.
During the Syrian Civil War on 11 February 2013 the dam was captured from government forces by the Opposition fighters, and during the late 2014 Islamic State took control of the dam facilities.
In late January 2017 Kurdish-Arab alliance known as Syrian Democratic Forces (SDF) started advancing toward Tabqa dam facilities. During that time ISIS started threatening that it will open floodgates, hoping to stop SDF advances or at least slow them down.
On 26 March SDF confirmed that they managed to capture most parts of the dam from ISIS, the dam itself was reported to have become inoperable.
