MULLAPPERIYAAR DAM

MULLAPPERIYAAR DAM



           The Mullaperiyar Dam is a masonry gravity dam on the Periyar River in the Kerala state of India. It is located 881 m (2,890 ft) above mean sea level, on the Cardamom Hills of the Western Ghats in Thekkady, Idukki District of Kerala, South India. It was constructed between 1887 and 1895 by the British Government to divert water eastwards to the Madras Presidency area (present-day Tamil Nadu). It has a height of 53.6 m (176 ft) from the foundation, and a length of 365.7 m (1,200 ft). The Periyar National Park in Thekkady is located around the dam's reservoir. The dam is located in Kerala on the river Periyar, but is controlled and operated under a period lease by neighboring Tamil Nadu state. Although the Periyar river has a total catchment area of 5398 km2 with 114 km2 in Tamil Nadu, the catchment area of the Mullaperiyar dam itself lies entirely in Kerala. The control and safety of the dam and the validity and fairness of the lease agreement have been points of dispute between Kerala and Tamil Nadu states. Supreme court judgment came in 27 February 2006, allowing Tamil Nadu to raise the level of the dam to 152 ft (46 m) after strengthening it. Responding to it, Mullaperiyar dam was declared an 'endangered' scheduled dam by the Kerala Government under the disputed Kerala Irrigation and Water Conservation (Amendment) Act, 2006.
