The '''Indira Sagar Dam''' is the largest dam in [[India]], in terms of volume of water stored in the reservoir. It is located on the [[Narmada River]] at the town of [[Narmada Nagar]], [[Punasa]] in the [[Khandwa district]] of [[Madhya Pradesh]] in [[India]]. The foundation stone of the project was laid by the [[prime minister of India]] [[Indira Gandhi]] on 23 October 1984. The construction of the main dam started in 1992. The downstream projects of ISP are [[Omkareshwar]], [[Maheshwar]], and [[Sardar Sarovar Project]]. To build it, a town of 22,000 people and 100 villages were displaced.<ref>{{Cite web|url=https://www.thehindu.com/thehindu/mag/2003/11/09/stories/2003110900040400.htm|archive-url=https://web.archive.org/web/20040122070332/http://www.thehindu.com/thehindu/mag/2003/11/09/stories/2003110900040400.htm|url-status=dead|archive-date=2004-01-22|website=[[The Hindu]]|title=Development or displacement?|access-date=2019-07-08}}</ref>

The Project involved construction of a 92 m high and 653 m long concrete [[gravity]] [[dam]]. It provides [[irrigation]] to 1,230 square kilometres of land with annual production of 2.7 billion units in the districts of [[Khandwa district|Khandwa]] and [[Khargone district|Khargone]] in Madhya Pradesh, and power generation of 1,000 MW (8x125 MW) installed capacity. In terms of storage of water, it is the largest reservoir in India, with capacity of 12.22 billion cu m or 12.2 km3, followed by [[Rihand Dam]], Uttar Pradesh then [[Nagarjuna Sagar Dam|Nagarjuna Sagar]] between [[Telangana]] and [[Andhra Pradesh]]. The dam was built as a joint venture between Madhya Pradesh irrigation and [[National Hydroelectric Power Corporation]]. It was commissioned in May 2005.<ref>[http://www.nhpcindia.com/Projects/English/Scripts/Prj_Features.aspx?Vid=15 NHPC Limited: Indira Sagar Power Station]</ref>

River [[Narmada]], the fifth largest river in India, with a river flow length of 1,312 km, originates from Amarkantak in Anuppur district of Madhya Pradesh. Narmada flows southwestward and after passing through Madhya Pradesh, Gujarat, and a small stretch in Maharashtra, it drains into the Arabian Sea near the Gulf of Khambhat. Indira Sagar Project (ISP) situated on River Narmada, 12 km from Punasa in Khandwa district of Madhya Pradesh, has been commissioned on 31 March 2005.

Indira Sagar Project is a multipurpose Project with an installed capacity of 1,000 MW, with annual energy generation of 2,698 million units in Stage I, 1,850 million units in Stage II, and 1,515 million units in Stage III, and annual irrigation of 2.65 Lac. Ha on a Culturable Command Area (CCA) of 1.23 Lac. Ha. Total [[Drainage basin|catchment area]] at the dam site is 61,642 km2. The regulated discharge from Indira Sagar Dam under mother Indira Sagar Projectwill enable Power generation at downstream projects of Omkareshwar and Maheshwar projects and irrigation from the Omkareshwar project and will also provide supplies to the Sardar Sarovar Project as directed by the Narmada Water Disputes Tribunal.<ref>{{Cite web |title=Indira Sagar /Narmada Sagar Project Major Irrigation Project JI00836 |url=https://indiawris.gov.in/wiki/doku.php?id=indira_sagar_narmada_sagar_project_major_irrigation_project_ji00836 |website=India-WRIS}}</ref> This project on [[Narmada River#Narmada basin|Narmada Basin]] with the largest reservoir in India, having 12.22 b m3 storage capacity. All the eight units commissioned by March 2005 ahead of schedule while generation from first unit was started from January 2004. The powerhouse is the second-largest surface powerhouse in India.
