Altınkaya Dam, Embankment dam in Samsun Province, Turkey
Altınkaya Dam is an embankment dam built across the Kızılırmak River, the longest river in Turkey, rising 195 m and spanning 634 m in length. It holds back a large reservoir and uses four turbines to generate electricity for the national grid.
The dam was built between 1980 and 1988 as part of a national push to expand Turkey's hydroelectric capacity. It forms part of a series of dams along the Kızılırmak, working together to manage water flow and energy output across the region.
The name Altınkaya means 'golden rock' in Turkish, referring to the rocky terrain along the Kızılırmak River where the dam was built. Today, the reservoir draws local families to its banks, especially on weekends.
The dam is located in Samsun Province and can be reached by road from the main coastal towns heading inland. Viewpoints along the reservoir's edge give a clearer sense of the structure's scale than the immediate surroundings near the dam face.
The Şahinkaya Canyon, which sits within the reservoir, has vertical rock walls that the Kızılırmak carved over millions of years before the dam existed. Boat trips on the reservoir pass through this narrow gorge, offering a view that is impossible to get by road.
