The Ermenek Dam is a double-curvature concrete arch dam located on the Göksu River in Karaman Province, Turkey. The 210 m (689 ft) tall dam (218 m (715 ft) from thalweg level) was the highest in Turkey at the time of its construction and currently ranks third after Deriner Dam and Yusufeli Dam (under construction). The development was backed by the Turkish State Hydraulic Works.
