Indirasagar Dam

The Indira Sagar Dam is a multipurpose project of the state Madhya Pradesh 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 late Smt Indira Gandhi, former Prime Minister of India 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[2]

The Project envisages construction of a 92 m high and 653 m 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 (8x125 MW) installed capacity. 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 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 on May 2005.[3]

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 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. Indira Sagar Project is the mother project for the downstream projects 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. It has really provided the villages near Narmada with river water for irrigation.

Indirasagar reservoir project has submerged 40,332 hectares of forests, 44,345 hectares of agricultural land, and affected 30,739 families

Indian National Human Rights commission takes complaint of Salem-News.com’s Human Rights Ambassador complain into note regarding Omkareshwar and Indira Sagar Dams. Complaints cited by their Human Rights Ambassador William Nicholas Gomes, over water levels being raised to the point that they literally drowned a local community, have been recognized by the National Human Rights Commission in India.[4][5]
