Tamil Nadu-Kerala dam row (alternatively India dam row) is an ongoing row and the long legal battle between the Indian states of Tamil Nadu and Kerala about the Mullaperiyar dam on the Periyar river. Although the 116-year-old Mullaperiyar dam is located in Kerala, it is operated by the government of Tamil Nadu which signed a 999-year lease agreement with the former British government to irrigate farmland on its side. The agreement was signed by the Secretary of Madras State (now Tamil Nadu) under the British Raj and the King of Travancore. Kerala now says the dam is too old and dilapidated and poses immense danger to millions of people living in the region and that it needs to be destroyed and rebuilt - a move opposed by Tamil Nadu. Tamil Nadu maintains that the dam was repaired in 1979 and insists the dam`s walls have been strengthened and that it can hold more water than the current level of 136 ft (41m).
