A Hittite inscription in Luwian hieroglyphs found during excavation of the area indicates that the structure was dedicated to the Hittite goddess Ḫepat. This goddess was honoured by Puduhepa, the wife of Great King Hattusili III, who called herself the goddess' servant. From a cuneiform document it is known that her son, Tudhaliya IV, who succeeded Hattusili, had ten dams built in the Hittite empire around 1240 BC after a period of drought.Yasemin Kuşlu, Üstün Şahin: "Water Structures in Anatolia from Past to Present" Journal of Applied Sciences Research, vol. 5, no. 12 (2009) pp. 2109–2116 From this it may be concluded that the Gölpınar dam is the work of Tudhaliya. It provided irrigation water and possibly drinking water to the inhabitants of Alaca Höyük.Günther Garbrecht, "Historische Wasserbauten in Ost-Anatolien" In Christoph Ohlig (ed.): Wasserbauten im Königreich Urartu und weitere Beiträge zur Hydrotechnik in der Antike pp. 90 GoogleBooks
