Important PointsHistory and extent of dams in India:
- India’s first dam is the Kallanai built on the Cauvery river by King Karikalan of the Chola dynasty around 2,000 years ago.
- The dam, which is still functional and irrigates millions of acres, spans 329 m in length and 20 m in width.
- However, it was only post-independence that India’s love for big dams became more intense with the commissioning of a slew of projects including the Hirakud (1957), Gandhisagar (1960), Bhakra-Nangal (1963) and Nagarjuna Sagar (1967).
- Since then, the country has been continuously working on reining in its rivers for want of power, irrigation and domestic and industrial water supply needs.
- Almost half of the large dams in the country were built in the two decades of 1970-90.
- Maharashtra has the maximum number of large dams in the country (1845) followed by Madhya Pradesh (905) and Gujarat (666).
