Limestone forms the foundations for the Atatürk dam. If such landslides cause an artifical lake by blocking the Euphrates River, the Karakaya hydroelectric power station could be flooded. However, on the downstream side of the right slope, the Tillo–Bego–Senketo landslides have been an important risk to the dam. The Karakaya dam is constructed on metamorphic rocks thus only allowing minimal water leakage. A more recent study on the volume of leakage showed it to be reduced to 7–8 m 3 /s, with this amount remaining constant. In spite of this, when the reservoir was filled, 26–30 m 3/s of water leaked from the Keban Creek. In order to prevent this water leakage, an intensive grouting programme was applied. From the author and his colleagues' studies, it has been shown that water would leak from the left side of Keban dam reservoir, forming a spring in the Keban Creek. The Keban dam's basement is formed by karstic rock, named Keban marble. In the belief that the cost of irrigation by the Atatürk dam's water would be high, the increase of the height of Atatürk dam was preferred to the construction of the Gölköy dam. The initial plans involved a 60 m high Gölköy dam, downstream of the Karakaya dam, with the Atatürk dam 60 m lower than it is currently. The first three of these dams have been completed construction on the Birecik and Karkamis dams is underway. In order to use the energy and irrigation potential of the Euphrates River, a series of dams have been designed (upstream to downstream) Keban, Karakaya, Karababa (Atatürk), Birecik and Karkamis.
