The first plans for a dam in the Syrian part of the Euphrates date to 1927, but these were not carried out. In 1957, an agreement was reached with the Soviet Union for technical and financial aid for the construction of a dam in the Euphrates, and in 1960 a financial agreement was signed with West Germany. Another agreement to finance the project was signed with the Soviet Union in 1965. The project included a hydroelectric power station in the Tabqa Dam, and the construction of a vast irrigation network capable of irrigating of land on both sides of the Euphrates. Construction of the dam lasted between 1968 and 1973 and the flooding of the reservoir commenced in 1974 by reducing the flow of the Euphrates. The project was completed under the presidency of Hafez al-Assad as part of his modernization policies and agricultural reforms. In 1975, Iraq complained that the flow of the Euphrates had been reduced below an acceptable level and threatened to bomb the Tabqa Dam; mediation by Saudi Arabia and the Soviet Union eventually settled this dispute.
