Idukki Dam
The Idukki Dam, located in Kerala, India, is a 555 foot tall arch dam. The dam stands between the two mountains - Kuravanmala (839)m and Kurathimala (925)m. It was constructed and is owned by the Kerala State Electricity Board.
It is built on the Periyar River, in the ravine between the Kuravan and Kurathi Hills in Kerala, India. At 167.68 metres, it is one of the highest arch dams in Asia. It started generating power on 4 October 1975. 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 in area. The stored water is used to produce electricity at the Moolamattom Power house, which is located inside nearby rocky caves. The Government of Canada aided in the building of the dam with long term loans and grants.
