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]

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 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. [3] This project on 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.
The Narmada River, previously also known as Narbada or anglicised as Nerbudda, is the 5th longest river in India and overall the longest west-flowing river in the country. It is also the largest flowing river in the state of Madhya Pradesh. This river flows through the states of Madhya Pradesh and Gujarat in India. It is also known as the "Lifeline of Madhya Pradesh and Gujarat" due to its huge contribution to the two states in many ways. The Narmada River rises from the Amarkantak Plateau in Anuppur district in Madhya Pradesh. It forms the traditional boundary between North and South India and flows westwards for 1,312 km (815.2 mi) before draining through the Gulf of Khambhat into the Arabian Sea, 30 km (18.6 mi) west of Bharuch city of Gujarat.

Harsud railway station is a railway station, situated at Harsud, Madhya Pradesh. Its station code is HRD. It serves Harsud city. The station consists of two platforms, neither well sheltered. It lacks many facilities including water and sanitation. Old station is presently defunct. Old Harsud station was submerged under the waters of the Indirasagar Dam in July 2004. Due to this the existing railway line between Itarsi Junction railway station(station code ET) & Khandwa Junction railway station(station code KNW) was abandoned & dismantled. A New 10 kilometres (6.2 mi) new line was laid & Harsud railway station(HRD) was shifted to new location increasing the distance by 14 kilometres (8.7 mi). Current distance between Itarsi Junction railway station(station code ET) & Khandwa Junction railway station(station code KNW) is 183 kilometres (114 mi), which was 169 kilometres (105 mi) before construction of Indirasagar Dam Reservoir in July 2004. The old railway line still exist from Talvadiya Junction railway station(station code TLV) to Singaji railway station(station code SJ) connecting Indirasagar Dam Thermal Power Station.
