Idukki Dam

The 555-foot arch dam over the Periyar River in Idukki is the biggest arch damn in Asia and the third tallest dam in India. Built and owned by the Kerala State Electricity Board, it stands between the Kuravan and Kurathi Hills. Two other dams were constructed along with this at Cheruthoni and Kulamavu. The Moolamattom Power house near Thodupuzha draws water for power from the artificial lake created by the three dams.

According to historical records, in 1922, the head of the Araya race, Shri Kolumban revealed the beautiful mountains and the water flow to his friend, the Malankara Estate Superintendent Thomas, during a hunt. A report was submitted to the Government of Travancore in 1932 for the possibility of constructing a dam for power generation. After a detailed survey was made in 1956 and allied paperwork done, the construction of the dam was commissioned in 1969.

With Canadian aid, the scope of construction of the dam was revised and after it was built, the then Prime Minister Smt. Indira Gandhi commissioned the commercial operation of the dam on 12 February 1976.

History Of Mullaperiyar Dam – Thekkady

The much controversial Mullaperiyar Dam stands after the confluence of the Mullayar and Periyar rivers in Idukki, and has been so named. In 1886, the then Maharaja of Travancore, forced by the British, signed an indenture with the Secretary of State for India for Periyar irrigation works for a lease period of 999 years. And by this clause, parts of Tamil Nadu such as Theni, Madurai, Sivaganga and Ramanathapuram will be irrigated by the water diverted by the dam and at a later stage, the electricity produced from it. The construction of the dam started in 1887 and it started operations in 1895. It is a masonry gravity dam running a length of 1,200ft and a height of 176ft.

The dam and its reservoirs are located within the Periyar National Park, Thekkady. More than two lakh acres of land is irrigated by the dam’s waters. The water is transported via a 1.6-km tunnel that reaches the Churuliyar and Vaigai rivers in Tamil Nadu.
