The Construction of the Haditha Dam was begun in 1977 and it was completed in 1988. Investigation works and preparation of the general design and specifications were made by Soviet organizations in contracts with the Iraqi Government under the Treaty of Technical and Economic Cooperation between the two governments. The All-Union Institute” Hydroprojekt” of Moscow took up the guidance of the investigations, preparation of final design, detailed design, and the preparation of the detailed specification of the earth-fill dam. The construction works of the earth-fill dam were done by the Iraqi State Organization for Dams (SOD) with technical Soviet support. The detailed design and construction of the powerhouse were awarded by (SOD) to Energoprojekt – Hydrogradnja from the previous Yugoslavia. The preliminary design of the powerhouse was done by Hydroprojekt Institute- Moscow, excavation of the powerhouse pit by (SOD) and Soviet support. The long period of investigation and construction was in lieu of procedures of similar works carried out in the Soviet Union. The usage of mealy dolomite as a core material in this dam for the first time in the world required extensive laboratory and site testing of this material to prove its suitability. The usage of the asphaltic concrete diaphragm in conjunction with the dolomitic core required conducting additional testing. These and the performance of grouting tests meant that the detailed specification could only be issued gradually according to the progress of the works. The long period of construction was also in part due to the volume of research work and testing programs that were necessary. The selected site of Haditha Dam is located in a narrow part of the Euphrates River few kilometers upstream from Haditha city. This selection was determined by the topographic and geological conditions and mode of occurrence of karstified rocks in the abutments of the dam in addition to the presence of local construction materials and the suitable conditions of performing the works. The total length of the dam is 9064 meters, which includes 8875 meters of the earth-fill part and 189 meters of the hydropower station and spillway combined structure which is located at the river channel. The earth-fill part is divided into 3310 meters on the right bank, 4985 meters on the left bank, and another 580 meters in the river channel. In Figure above the general layout of the dam is given. The maximum height of the dam is 57 meters from the deepest point at the river channel, which was dictated by topographical and hydrological factors. The dam crest level, according to these considerations was fixed at 154.00 m (a.s.l.), and the width of the crest was 20 m.
