This is the world's second and Asia's first arch dam.
The Idukki Dam is a double-curvature thin arch dam constructed across the Periyar River in a narrow gorge between two granite hills locally known as Kuravan and Kurathi, in Idukki district, in the state of Kerala, India. It is constructed and owned by the Kerala State Electricity Board. It supports a 780 MW hydroelectric power station in Moolamattom, which started generating power on 4 October 1975. At 168.91 metres (554.2 ft), it is one of the highest arch dams in Asia. The Indo-Canadian project was inaugurated by Prime Minister Indira Gandhi on February 17, 1976.
