History of Bhakra Nangal dam

  • In 1908, Sir Louis Dane, the Lieutenant Governor of Punjab, suggested a reservoir to be built on Sutlej by building dams for storage and power development.
  • However, due to prohibitive costs, the project was shelved. Over the decades, many other reports were submitted and studied, and finally in 1948 the Bhakra Nangal project actually took shape with the aim of providing irrigation, power generation, and preventing floods in the Sutlej-Beas river valley.

Objectives of the Bhakra dam include Irrigation

  • One of the main purposes of the dam is to store water for irrigation for more than 10 million acres of fields in Punjab, Haryana, and Rajasthan, by a regulated release throughout the year.
  • The water flows down from the Bhakra dam downstream to the Nangal dam where it is controlled and released into the Nangal Hydel Channel. The dam also counteracts the damage caused due to monsoon floods.
