The Idukki Dam, located in Kerala, India, is currently the 14th largest arch dam in Asia, at 555 feet in height with a width of 650 ft. It is the world's second and Asia's first arch dam. The Idukki Arch Dam is constructed across the flabbergasting Kuravan (839 feet) and Kurathi (925 feet) hills. It is built on the Periyar River. Technically, the dam type is a concrete double, curvature parabolic, thin arc dam. This dam was constructed along with two other dams at Cheruthony and Kulamavu. Together, the three dams have created an artificial lake that is 60 km² wide. The stored water is used to produce electricity at the Moolamattom Power house. The dam proves to be a unique, fascinating, and appreciable site in Idukki. The dam is situated near the Cheruthoni barrage and extents to an altitude of 550 ft.
