The Indirasagar Dam is a multipurpose project of Madhya Pradesh on the Narmada River at Narmadanagar in the Khandwa district of Madhya Pradesh in India. The foundation stone of the project was laid by late Smt Indira Gandhi, former Prime Minister of India on 23 October 1984. The construction of main dam started in 1992. The downstream projects of ISP are Omkareshwar, Maheshwar, and Sardar Sarovar Project.

The Project envisages construction of a 92 metres high and 653 metres long concrete gravity dam. It provides Irrigation in 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 installed capacity (8x125). The reservoir of 12,200,000,000 m³ (9,890,701 acre·ft) was created. In terms of storage of water, it withholds the largest reservoir in India, with capacity of 12.22 billion cu m, followed by Bharkra Nangal in Himachal Pradesh. The dam, built as a joint venture between Madhya Pradesh irrigation and National Hydroelectric Power Corporation is the source of the Indira Gandhi Canal. It was commissioned on May 2005.^[2]

Indira Sagar Project

Introduction

River Narmada , 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 westward and after passing through Madhya Pradesh, Gujarat, and Maharashtra, it drains into Arabian Sea near Gulf of Combay. Indira Sagar Project (ISP) situated on River Narmada, 10 32 km from Mundi in Khandwa district of Madhya Pradesh is 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. Indira Sagar Project is the mother project for the downstream projects on Narmada Basin with largest reservoir in India, having 12.22 Bm3 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.
