The Tabqa Dam, or al-Thawra Dam as it is also named, most commonly known as Euphrates Dam, is an earthen dam on the Euphrates, located 40 kilometres (25 mi) upstream from the city of Raqqa in Raqqa Governorate, Syria. The city of Al-Thawrah is located immediately south of the dam. The dam is 60 metres (200 ft) high and 4.5 kilometres (2.8 mi) long and is the largest dam in Syria. Its construction led to the creation of Lake Assad, Syria's largest water reservoir. The dam was constructed between 1968 and 1973 with help from the Soviet Union. At the same time, an international effort was made to excavate and document as many archaeological remains as possible in the area of the future lake before they would be flooded by the rising water. When the flow of the Euphrates was reduced in 1974 to fill the lake behind the dam, a dispute broke out between Syria and Iraq that was settled by intervention from Saudi Arabia and the Soviet Union. The dam was originally built to generate hydroelectric power, as well as irrigate lands on both sides of the Euphrates. The dam has not reached its full potential in either of these objectives.

The Ilısu Dam is a concrete-face rock-fill dam on the Tigris near the village of Ilısu and along the border of Mardin and Şırnak Provinces in Turkey. It is one of the 22 dams of the Southeastern Anatolia Project and its purpose is hydroelectric power production, flood control and water storage. When operational, the dam will support a 1,200 MW power station and will form a 10.4 billion m3 reservoir. Construction of the dam began in 2006 and was originally expected to be completed by 2016. As part of the project, the much smaller Cizre Dam is to be constructed downstream for irrigation and power. The dam has drawn international controversy, because it will flood portions of ancient Hasankeyf and necessitate the relocation of people living in the region. Because of this, the dam lost international funding in 2008. Most historical structures in Hasankeyf were moved to the new Hasankeyf prior to the filling of the dam. The dam began to fill its reservoir in late July 2019. Due to rainfall, the dam has achieved water levels up to 100m above the river bed and stored 5 billion cubic meters of water. The water level had reached an elevation of 498.2m on 1 April 2020.

Hydroelectricity is a major source of electricity in Turkey, due to its mountainous landscape and many rivers. The country's main river basins are the Euphrates and Tigris. Over 700 hydropower plants have been built, and they make up about 30% of the country's electricity generating capacity. Annual generation varies greatly, and in rainy years lots of hydroelectric power can be generated. Government policies have generally supported building dams, but some are controversial in neighbouring countries, and some raise concerns about damage to the environment and wildlife.
