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 was displaced.^[1]

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 and 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 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.^[2]
