The Narmada River (IPA: [nəɾməd̪aː]), 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 and is known as their lifeline due to its 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.[2][3]

It is one of only two major rivers in peninsular India that runs from east to west (longest west flowing river), along with the Tapti River. It is one of the rivers in India that flows in a rift valley, bordered by the Satpura and Vindhya ranges. As a rift valley river, the Narmada does not form a delta; Rift valley rivers form estuaries. Other rivers which flow through the rift valley include the Damodar River in Chota Nagpur Plateau and Tapti. The Tapti River and Mahi River also flow through rift valleys, but between different ranges. It flows through the states of Madhya Pradesh (1,077 km (669.2 mi)), and Maharashtra, (74 km (46.0 mi)), (39 km (24.2 mi)) (actually along the border between Madhya Pradesh and Maharashtra (39 km (24.2 mi)) and then the border between Maharashtra and Gujarat (74 km (46.0 mi)) and in Gujarat (161 km (100.0 mi)).[4]

The Periplus Maris Erythraei (c. 80 AD) called the river the Namnadius (Ναμνάδιος),[5] Ptolemy called it Namadus (Νάμαδος) and Namades (Ναμάδης)[6] and the British Raj called it the Nerbudda or Narbada.[7][8] Narmada is a Sanskrit word meaning "The Giver of Pleasure".[9]

Course

The source of the Narmada is a small reservoir, known as the Narmada Kund. It is located at Amarkantak on the Amarkantak Plateau[10][4] in the Anuppur District on Shahdol zone of eastern Madhya Pradesh.[11] The river descends from Sonmuda, then falls over a cliff as Kapildhara waterfall and meanders in the hills, flowing through a tortuous course crossing the rocks and islands up to the ruined palace of Ramnagar. Between Ramnagar and Mandla, 25 km (15.5 mi) further southeast, the course is comparatively straight with deep water devoid of rocky obstacles. The Banger joins from the left. The river then runs north–west in a narrow loop towards Jabalpur. Close to this city, after a fall of some 9 m (29.5 ft), called the Dhuandhara (the fall of mist), it flows for 3 km (1.9 mi), in a deep narrow channel through the magnesium limestone and basalt rocks called the Marble Rocks; from a width of about 90 m (295.3 ft), above, it is compressed in this channel of (18 m (59.1 ft)), only. Beyond this point up to its meeting the Arabian Sea, the Narmada enters three narrow valleys between the Vindhya scarps in the north and the Satpura range in the South. The southern extension of the valley is wider at most places. These three valley sections are separated by the closely approaching line of the scarps and the Satpura hills.

Marble Rocks alongside Narmada River

Emerging from the Marble Rocks the river enters its first fertile basin, which extends about 320 km (198.8 mi), with an average width of 35 km (21.7 mi), in the south. In the north, the valley is limited to the Barna–Bareli plain terminating at Barkhara Hills opposite Narmadapuram. However, the hills again recede in the Kannod plains. The banks are about (12 m (39.4 ft)) high. It is in the first valley of the Narmada that many of its important tributaries from the south join it and bring the waters of the northern slopes of the Satpura Hills.[8] Among them are: the Sher River, Shakkar River, the Dudhi River, the Tawa (biggest tributary) and the Ganjal. The Hiran, the Barna, the Choral, the Karam and the Lohar are the important tributaries joining from the north.

Below Handia and Nemawar to Hiran fall (the deer's leap), the river is approached by hills from both sides. In this stretch the character of the river is varied. Omkareshwar, sacred to Shiva is an important place of worship in Madhya Pradesh. At first, the descent is rapid and the stream, quickening in pace, rushes over a barrier of rocks. The Sikta and the Kaveri join it below the Khandwa plain. At two points, at Mandhar, about 40 km (24.9 mi) below Nemawar, and Dadrai, 40 km (24.9 mi) further down near Punasa, the river falls over a height of about 12 m (39.4 ft).

A few kilometres further down in Barwaha the Narmada enters the Mandleshwar plain, the second basin about 180 km (111.8 mi) long and 65 km (40.4 mi) wide in the south. The northern strip of the basin is only 25 km (15.5 mi). The second valley section is broken only by Saheshwar Dhara fall. The early course of about 125 km (77.7 mi) up to Markari falls is met with a succession of cataracts and rapids from the elevated table land of Malwa to the low level of Gujarat plain. Towards the west of this basin, the hills draw very close but soon dwindle down.[citation needed]

Below Makrai, the river flows between Vadodara district and Narmada district and then meanders through the rich plain of Bharuch district of Gujarat state. The banks are high between the layers of old alluvial deposits, hardened mud, gravels of nodular limestone and sand. The width of the river spans from about 1.5 km (0.9 mi) at Makrai to 3 km (1.9 mi) near Bharuch and to an estuary of 21 km (13.0 mi) at the Gulf of Cambay. An old channel of the river, 1 km (0.6 mi) to 2 km (1.2 mi) south from the present one, is very clear below Bharuch. The Karanjan and the Orsing are the most important tributaries in the original course. The former joins at Rundh and the latter at Vyas in Vadodara district of Gujarat, opposite each other and form a Triveni (confluence of three rivers) on the Narmada. The Amaravati and the Bhukhi are other tributaries of significance. Opposite the mouth of the Bhukhi is a large drift called Alia Bet or Kadaria Bet.[citation needed]

The tidal rise is felt up to 32 km (19.9 mi) above Bharuch, where the neap tides rise to about a metre and spring tide 3.5 m (11.5 ft). The river is navigable for vessels of 95 tonnes (i.e., 380 Bombay candies) up to Bharuch and for vessels up to 35 tonnes (140 Bombay candies) up to Shamlapitha or Ghangdia. The small vessels (10 tonnes) voyage up to Tilakawada in Gujarat. There are sand bases and shoals at mouth and at Bharuch. The nearby island of Kabirvad, in the Narmada River, features a gigantic Banyan tree, which covers 10,000 square metres (2.5 acres).[citation needed]

Narmada basin

[edit]

The Narmada basin, hemmed between Vindhya and Satpura ranges, extends over an area of 98,796 km2 (38,145.3 sq mi) and lies on the northern extremity of the Deccan Plateau. The basin covers large areas in the states of Madhya Pradesh (82%), Gujarat (12%) and a comparatively smaller area in Maharashtra (4%) and in Chhattisgarh (2%). 60% of the basin is made up of arable land, 35% is forest cover and 5% is made up of other types of land such as grassland or wasteland.[12] In the entire course of the river of 1,312 km (815.2 mi), there are 41 tributaries, out of which 22 are from the Satpura range and the rest on the right bank are from the Vindhya range.[4] Dhupgarh (1,350 m), near Pachmarhi is the highest point of the Narmada basin.[13]

The basin has five well defined physiographic regions. They are:(1) The upper hilly areas covering parts of Anuppur, Mandla, Dindori, Balaghat and Seoni, (2) The upper plains covering parts of Jabalpur, Narsinghpur, Chhindwara, Narmadapuram, Betul, Harda, Raisen and Sehore districts, (3) The middle plains covering parts of Khandwa, Khargone, Dewas, Indore and Dhar, (4) The lower hilly areas covering parts of Barwani, Alirajpur, Nandurbar, Chhota Udepur and Narmada, and (5) the lower plains covering mainly the districts of Narmada, Bharuch, and parts of Vadodara district. The hill regions are well forested. The upper, middle and lower plains are broad and fertile areas, well suited for cultivation. The Narmada basin mainly consists of black soils. The coastal plains in Gujarat are composed of alluvial clays with a layer of black soils on the surface.[14]

The valley experiences extremes of hydrometeorological and climatic conditions with the upper catchment having an annual precipitation in the range of 1,000 mm (3.3 ft) to 1,850 mm (6.1 ft) and with half or even less than half in its lower regions (650 mm (2.1 ft)–750 mm (2.5 ft)); the diversity of vegetation from lush green in the upper region to dry deciduous teak forest vegetation in the lower region is testimony to this feature.[4]

Geology

[edit]

About 160 million years ago, the supercontinent Pangea broke into two large masses. The northern part was Laurasia and the southern continental mass was Gondwana.[15] Between the two continents, a large sea, Tethys existed. Presently the Himalayas and the Tibetan Plateau have taken the position of the ancient Tethys Ocean. The Gondwana was intruded by few large marine transgressions. A deep gulf or sea existed along the Sindh-Baluchistan and Kutch. At one time, a marine ravine penetrated the very centre of Peninsular India through a narrow inlet along the present valley of Narmada. During this time India was divided into two halves by narrow strips of marine transgressions and there was no land communication between the Peninsular and northern India. Along the Narmada Valley, several patches of sediments have been deposited which contains ancient remains of animals. These fossils are similar to those found along the tracts of Tapi river. Such similarity probably suggests that even about 3 million years ago, Narmada and Tapi were confluent and the separate fate of these two rivers was decided by recent earth movements. The Bhedaghat falls of Narmada, near Jabalpur, was probably created during one such movement. The Narmada Valley is a graben, a layered block of the Earth's crust that dropped down relative to the blocks on either side due to ancient spreading of the Earth's crust. Two normal faults, known as the Narmada North fault and Narmada South fault, parallel to the river's course, and mark the boundary between the Narmada block and the Vindhya and Satpura blocks or Horsts which rose relative to the Narmada Graben. The Narmada's watershed includes the northern slopes of the Satpuras, and the steep southern slope of the Vindhyas, but not the Vindhyan tableland, the streams from which flow into the Ganges and Yamuna.[8]

Significance in Hinduism

Deity status

[edit]

Like the Ganges, the Narmada River is a goddess and a river in Hinduism. The Matsya Purana states that all of the banks along the Narmada are sacred.[16] Ptolemy called the Narmada River 'Nammadus' and the author of the Periplus called it 'Nammadios.'[17]

There are many stories about the origin of the Narmada River. According to the Rewa Khand, the Narmada was created from Shiva's perspiration while he was performing penance on Mount Riksha.[16] Due to this, the Narmada River is known as Shiva's daughter.[16] In another legend, two teardrops fell from the eyes of Brahma, the creator of the universe, which yielded two rivers – the Narmada and the Son.[17]

Narmada is also said to have been engaged with the Sonbhadra, another river flowing on the Chota Nagpur Plateau. According to the Puranas, the Narmada is also called the Reva, from its leaping motion (from the root 'rev') through its rocky bed.[18]

The Narmada River is also worshipped as mother goddess Muktidayani, or liberating mother.[19]

Adi Shankara met his guru Govinda Bhagavatpada in Omkareshwar, a town on the banks of the Narmada.[20]

Source of sacred linga pebbles

[edit]

Narmada is also considered sacred because of the pebbles known as banalinga that are found on the river bed. The pebbles are made up of white quartz and are linga shaped.[17] They are believed to be the personified form of Shiva and there is a popular saying, "Narmada Ke Kanker utte Sankar" which means that 'Shiva is in the pebbles of Narmada'.[20]

Pilgrimage

[edit]

Uttarvahini Panchkoshi Narmada Parikrama (literally "Northward-flowing 5-kos Narmada Circumbulation"), is a yearly month-long a significant religious pilgrimage dedicated to the Narmada River, spans a 14-kilometer path beside the Narmada River in Gujarat's Narmada region on a stretch of the river is notable for its unusual northward flow, a direction considered exceptionally sacred in Hindu beliefs. Pilgrims traditionally traverse this route on foot, visiting important riverbanks known as ghats, including Shaherav Ghat, Rengan Ghat, Rampura Ghat, and Tilakwada Ghat. More than just a physical act of walking around the river, this parikrama offers an immersion into the cultural heritage of central India, providing insights into the local ways of life, customs, and religious observances. The Puranas state, "Ganga Snane, Yamuna Paane, Narmada darshane, Tatha Taapi Smarane" meaning "liberation is attained by bathing in the Ganges, drinking the water of the Yamuna, having darshan of the Narmada, and remembering the Tapi", i.e. "while bathing in the Ganges and drinking Yamuna’s water are sacred, merely having darshan of the Narmada is believed to bestow liberation". Of the 150,000 rivers in the world, 400 are in India, Narmada is the only river in the world venerated through a sacredparikrama or circumambulation of the river.[21]

The importance of the Narmada River as sacred is testified by the fact that the pilgrims perform a holy pilgrimage of a parikrama or circumambulation of the river.[22] The Narmada Parikrama, as it is called, is considered to be a meritorious act that a pilgrim can undertake.[8]

The Uttarvahini Narmada Parikrama, a significant pilgrimage, involves a 14-kilometer circumambulation along the Narmada River. This journey can commence at either the Rampura ghat or Tilakwada. Starting from Rampura ghat, pilgrims proceed along the riverbank towards Tilakwada, crossing a temporary bridge at Saherav before arriving at Rengan ghat. To complete the circle, they then cross the river by canoe. Alternatively, the parikrama can begin in Tilakwada, leading devotees through Rengan and Rampura, then via Saherav, ultimately returning to Tilakwada. Regardless of the starting point, the devotees traverse a seven-kilometer stretch on each side of the river, totaling the 14-kilometer sacred walk.[23]

Many sadhus and pilgrims walk on foot from the Arabian Sea at Bharuch in Gujarat, along the river, to the source in Maikal Mountains (Amarkantak hills) in Madhya Pradesh and back along the opposite bank of the river. It is a 2,600-kilometre (1,600 mi) walk.[24] The spiritual journey is usually taken for 3 years, 3 months and 13 days and the pilgrims are stipulated not to cross the river at any point of time.[25] Important towns of interest in the valley are Jabalpur, Barwaha, Narmadapuram, Harda, Narmada Nagar, Omkareshwar, Dewas (Nemavar, Kity, Pipri), Mandla and Maheshwar in Madhya Pradesh, and Rajpipla and Bharuch in Gujarat. Some places of historical interest are Chausath Yogini Temple, Joga Ka Quilla, Chhatri of Baji Rao Peshwa and Bhimbetka, and among the falls are the Dhuandhar Falls, Dugdhdhara, Dhardi falls, Kapiladhara and Sahastradhara.[26]

The pilgrimage, which is held in Hindu month of Chaitra (Late March to April), at least 100,000 daily pilgrims for a month, or at least 3 million pilgrims over the duration of the event making is among one of the largest peaceful gatherings in the world.[23]

Ecology

[edit]

The lower Narmada River Valley and the surrounding uplands, covering an area of 169,900 km2 (65,598.8 sq mi) consists of dry deciduous forests. The ecoregion lies between moister forests to the northeast, southeast, and southwest, which receive greater rainfall from the southeast monsoon, and the drier forests and scrublands of the Deccan to the south and Malwa and Gujarat to the west and northwest. The natural vegetation of the region is a three–tiered forest.[citation needed] Tectona grandis is the dominant canopy tree, in association with Diospyros melanoxylon, Dhaora (Anogeissus latifolia), Lagerstroemia parviflora, Terminalia tomentosa, Lannea coromandelica, Hardwickia binata and Boswellia serrata. Riparian areas along the regions' rivers and streams, which receive yearg– round water, are home to moist evergreen forests, whose dominant tree species are Terminalia arjuna, Syzygium cumini (Jambul), Syzygium Heyneanum, Salix tetrasperma, Homonoia riparia, and Vitex negundo.[27]

The ecoregion is home to 76 species of mammals and to 276 bird species, none of which are endemic.[27] About 30% of the ecoregion is covered in relatively intact vegetation. The ecoregion includes some large blocks of habitat in the Vindhya and Satpura ranges. About 5% of the ecoregion lies within protected areas, including Bandhavgarh, Panna, and Sanjay National Parks.

Some of the important national parks and wild life sanctuaries in the valley are the following: Kanha National Park located in the upper reaches of Narmada, about 18 km (11.2 mi) from Mandla, boasts of several wild animals including the Tiger. Two tributaries of Narmada, namely, Sulkum and Banjar, flow through this park. It is one of the best National Parks of Asia, which has been described vividly by Rudyard Kipling in his famous creation The Jungle Book.[28][29]

Satpura National Park, set up in 1981, is located in Narmadapuram district of Madhya Pradesh. Its name is derived from Satpura hill ranges (Mahadeo hills) and covers an area of 524 km2 (202.3 sq mi) and along with the adjoining Bori and Panchmarhi Sanctuaries, provides 1,427 km2 (551.0 sq mi) of unique central Indian Highland ecosystem. Satpura National Park, being part of a unique ecosystem, is very rich in biodiversity. The fauna comprises tiger, leopard, sambar, chital, bhedki, nilgai, four-horned antelope, chinkara, gaur, wild boar, wild dog, sloth bear, black buck, fox, porcupine, flying squirrel, mouse deer, Indian giant squirrel. There are a variety of birds. Hornbill and peafowl are the common birds. The flora of the national park consists of mainly sal, teak, tendu, aonla, mahua, bael, bamboo, and a variety of grasses and medicinal plants.

Forest areas outside protected areas are also quite rich in floral and faunal diversity.

Mandla Plant Fossils National Park, Dindori National fossils park Ghughuya is situated in Dindori district of Madhya Pradesh in India. This national park has plants in fossil form that existed in India anywhere between 40 million and 150 million years ago spread over seven villages of Mandla District (Ghuguwa, Umaria, Deorakhurd, Barbaspur, Chanti-hills, Chargaon and Deori Kohani). The Mandla Plant Fossils National Park is an area that spreads over 274,100 m2 (2,950,387.8 sq ft). Such fossils are found in three other villages of the district also, but they lie outside the national park.[30][31]

The Pachmarhi Biosphere Reserve covers part of three civil districts viz., Narmadapuram, Betul and Chhindwara of Madhya Pradesh. The total area is 4,926.28 km2 (1,902.0 sq mi). It envelops three wildlife conservation units viz., Bori Sanctuary (518.00 km2), Satpura National Park (524.37 km2 (202.5 sq mi)), and Pachmarhi Sanctuary (461.37 km2 (178.1 sq mi)). Satpura National Park comprises the core zone and the remaining area of 4,501.91 km2 (1,738.2 sq mi)), surrounding the core zone serves as buffer zone. The area comprises 511 villages. The area exhibits variety of geological rock and soil formations. There is a wide spectrum of floral and faunal features that occupy the Satpura conservation area. It is one of the oldest forest reserves, which has an established tradition of scientific management of forests. It constitutes a large contiguous forest block that harbours a community of plant and animal species typical of the central highland region.[32]

Apart from the above national parks, there are also a number of natural preserves such as the Amarkantak, the Bagh Caves and the Bhedaghat. In compliance of the Environmental Action Plan for the Narmadasagar and Omkareswar HEPs, as per the recommendations of the Wildlife Institute of India three new protected areas may be created, which are, a) the Narmada National Park (496.70 km2), b) the Surmanya Sanctuary (126.67 km2) and c) Omkareshwar Sanctuary (119.96 km2) comprising a total area of 788.57 km2 (304.47 sq mi).[33]

Shoolpaneshwar Sanctuary in Gujarat, near the Sardar Sarovar dam site, previously called the Dumkal Sloth Bear Sanctuary (old sanctuary has been expanded four times) now covers an area of about 607 km2 (234.4 sq mi), comprises a major watershed feeding the Sardar Sarovar and Karjan reservoir (on the Karjan River, a tributary of Narmada in Gujarat). It is the habitat of mammals and a variety of birds, including eagles and hawks.[34][35]

Anthropological and archaeological sites

[edit]

The development of the Narmada river has led to the inundation of some archaeological and architectural sites. The Department of Archaeology, Museums and Archives, Government of Madhya Pradesh, undertook rescue excavations in response, and transplanted a number of temples.[36] An attempt to comprehensively list and publish lost sites has been undertaken by Jürgen Neuss.[37] Many Dinosaur fossils have been found in the Narmada valley. The first dinosaur fossil in India was discovered in 1828 by William Sleeman at Jabalpur.[38] In 1982 fossil remains of Rajasaurus narmadensis, which lived in the Cretaceous Period, was discovered.[17]

The Narmada Human, an extinct hominin species was discovered near Hathnora village in Sehore district in 1982, and is one of the earliest hominin bones in South East Asia. Other evidence or early hominin activity, including tools, have been found along the valley [39]

River development

[edit]

The Narmada river has a huge water resources potential, as much as 33,210,000 acre-feet (40.96 km3) of average annual flow (more than 90% of this flow occurring during the monsoon months of June – September), which according to estimates is greater than the combined annual flows of the Ravi, Beas and the Sutlej rivers, which feed the Indus basin. The 75% dependable flow is 28,000,000 acre-feet (35 km3).[40]

Sardar Sarovar Dam

[edit]

As one of the 30 dams planned on river Narmada, the Sardar Sarovar Dam is the largest structure to be built. It is the second largest concrete dam in the world in terms of the volume of concrete used in its construction, after the Grand Coulee Dam across the Columbia River, US.[41][42] It is a part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectricity multi-purpose dams on the Narmada River. After a number of cases before the Supreme Court of India (1999, 2000, 2003), by 2014 the Narmada Control Authority had approved a series of changes in the final height and the associated displacement caused by the increased reservoir, from the original 80 m (260 ft) to a final 163 m (535 ft) from foundation.[43][44]

Water dispute

[edit]

Investigations for harnessing the Narmada waters began in 1945 to 1946 by A. N. Khosla who was the chairman of the Central Waterways, Irrigation and Navigation Commission (CWINC). In 1948 the Khosla Committee recommended that further investigations be carried out on four of the seven proposed sites. The four sites included Tawa, Bargi, Punasa and the Broach Barrage and Canal Project.[45] In 1951 CWNIC was renamed Central Waterways & Power Commission (CWPC) and in 1957 a senior member of the CWPC selected further investigations to be completed at Navagam, a site that fell under the Broach Project. Navagam eventually became CWPC's preferred site because the geography allowed the dam's height to be raised higher. In 1960, the federal Government of India's Ministry of Irrigation and Power consultant team recommended that the Navagam Dam height be raised in one phase and that the drought prone areas in then Bombay State (modern day Saurashtra and Kutch regions) receive irrigation.[45]

On 1 May 1960 Bombay state was separated into the states of Maharashtra and Gujarat. The Navagam Dam site and Broach Project fell under the newly formed State of Gujarat and further development and planning was given to the Gujarat State government.[45] The Gujarat State government began planning studies for harnessing Narmada's water past the Punasa site in Madhya Pradesh. At the same time, the Government of Madhya Pradesh was also finalising a separate report for the Punasa Project. The competing plans led to inter-State water conflicts to arise because the Narmada did not have enough water supply to meet the requirements as planned by the two states. This began inter-State conflicts that went on for several years until 1963 when the Chief Ministers of Madhya Pradesh and Gujarat arrived at a set of compromises called the Bhopal Agreement. Gujarat State ratified the agreement but Madhya Pradesh did not, which led to another impasse.[45]

To break the logjam, a high-level Committee was appointed by the Government of India (GOI) in September 1964. In 1965, the Committee prepared a Master Plan for the basin, which involved construction of 12 major projects in Madhya Pradesh and the Navagam Dam in Gujarat. Gujarat endorsed the proposal, but Maharashtra did not. After intense parleys failed to resolve the problem, in 1968 GOI agreed to establish the Narmada Water Disputes Tribunal (NWDT) under the Interstate River Water Disputes Act of 1956 to adjudicate on the dispute relating to sharing of water of the interstate Narmada and its valley.[45]

After ten years of deliberations and taking into considering the development of the water resources of the basin as a whole gave its award December 1978.[46]

Even though the tribunal award resolved the initial issue of water sharing, the height of dam, benefit sharing and the mode of settlement of affected people caused serious difficulties in implementation, particularly of the Sardar Sarovar dam.[45]

The social movement Narmada Bachao Andolan (NBA) was formed to address environmental concerns and rehabilitation and resettlement of affected people. The movement created worldwide attention to the major development activity planned in the valley.[47] This resulted in the Bank conducting an Independent Review Mission (IRM) in 1991 of the Sardar Sarovar Project and identified several recommendations.[46] However, the IRM's report was neither accepted by the Government of India or the World Bank. Finally the Government of India decided to terminate further drawing from the World Bank loan and would complete the project with national resources.[46]

The Supreme Court has also deliberated on this issue for several years but finally upheld the Tribunal Award and allowed the construction to proceed, subject to conditions. The Court introduced a mechanism to monitor the progress of resettlement pari passu with the raising of the height of the dam through Grievance Redressal Authorities (GRA) in each of the party states. The court's decision referred in this document, given in the year 2000, after 7 years of deliberations, has paved the way for completing the project to attain full envisaged benefits.[48]

The Narmada River is a prominent west-flowing river of peninsular , originating from the plateau in 's and traversing approximately 1,312 kilometers westward through rift valleys between the Vindhya and Satpura ranges before discharging into the via the in . Its basin encompasses 98,796 square kilometers across (87% of the area), , , and a sliver of , supporting diverse ecosystems and human settlements with an average annual discharge influenced by variability. Revered in Hindu tradition as one of sacred rivers—second only to the in sanctity—the Narmada is mythologically linked to Lord , from whose perspiration or body it is said to have emerged, embodying purification and spiritual emancipation through rituals like bathing and the arduous Narmada Parikrama pilgrimage circumambulating its 2,600-kilometer course. The river's underpins vital and infrastructure, including the massive in and Indira Sagar Dam in , which collectively aim to harness its flow for drought mitigation and benefiting millions, though these multipurpose projects have ignited enduring disputes over inadequate rehabilitation of displaced communities, ecological degradation, and interstate water allocation, epitomized by the Narmada Bachao Andolan's campaigns since the 1980s.

Physical Geography

Course and Morphology

The Narmada River originates at Narmada Kund, a small perennial spring on the plateau in the Maikala Range of , at an elevation of 1,057 meters above sea level. From its source, the river flows westward in a distinctive transverse direction, covering a total length of 1,312 kilometers before discharging into the in the . Its course traverses for 1,077 kilometers, for 74 kilometers along the border with , and the remaining stretch through . The Narmada's morphology is defined by its flow through the , a tectonic bounded by the to the north and the to the south, resulting from faulting in the . This rift structure imparts a linear, straight path with limited lateral erosion and meandering, contrasting with the dendritic patterns of most peninsular rivers. The river maintains a steep longitudinal profile through rocky basaltic terrain, particularly in its upper and middle reaches, which contributes to high-velocity flow and features such as gorges and waterfalls, while its lower course widens into broader alluvial plains without forming a significant delta due to the abrupt entry into the sea. This geological confinement enhances the Narmada's erosive power along fault lines, carving deep valleys and exposing bedrock in places, with the river's bed dominated by coarse sediments and boulders in upstream sections transitioning to finer materials downstream. The morphology supports a consistent westward drainage pattern independent of the prevailing eastward tilt of the Indian Peninsula, underscoring the river's antiquity and structural control over its evolution.

Basin Characteristics

The Narmada River basin covers an area of 98,796 square kilometers, equivalent to about 3% of India's total geographical area. This primarily lies within , which accounts for the majority of the area, along with portions in , , and a minor extent in . The basin's coordinates range from 72°32' E to 81°45' E and 21°20' N to 23°45' N . Physiographically, the basin exhibits diverse topography, segmented into three sub-basins: the upper basin characterized by hilly terrain originating from the Plateau, the middle basin featuring landscapes with basaltic plateaus, and the lower basin transitioning to alluvial plains near the . Soils predominantly consist of black cotton soils, including deep, medium, and shallow variants, which support rain-fed but are prone to in steeper slopes. Land use within the basin is dominated by , covering approximately 54% of the area, followed by and settlements, reflecting the region's reliance on monsoon-dependent cultivation. The basin supports a population engaged largely in farming and tribal livelihoods, though exact figures vary by , with significant demographic in the central and lower reaches. Hydrologically, the basin's characteristics are influenced by a monsoon-dominated , with over 90% of annual rainfall concentrated in the , leading to high seasonal variability in availability.

Geological Formation

Tectonic History

The Narmada River flows westward through the Narmada Graben, a bounded by the to the north and the to the south, forming part of the extensive Narmada-Son Lineament (NSL), a major east-west trending tectonic discontinuity that segments the Indian Shield. This lineament, recognized as a paleo-rift system, originated from crustal weaknesses and divides the northern from the southern peninsular block, influencing regional drainage and seismicity. Tectonic evolution of the NSL involved multiple phases, beginning with Archaean- deformation that established initial crustal fabrics, followed by orogenic events such as the Orogeny around 1000–900 Ma, which contributed to basement structuring. Significant reactivation occurred during the , coinciding with linked to the India-Gondwana and intra-plate stresses, leading to the development of the Son-Narmada parallel to the Satpura trend and formation of the through block faulting. This period saw intense fault movements along the Narmada system, overlain by Deccan Trap (Upper to Lower ), which filled the basin with basaltic flows and influenced subsequent . Post-Cretaceous compression and inversion events modified the basin, with tectonic disturbances persisting into the , evidenced by uplift, fault reactivation, and geomorphic adjustments along the NSL. Neotectonic activity, including basin inversion and seismic events, underscores the lineament's ongoing intra-plate deformation, with GPS data indicating crustal strain accumulation that segments the Indian plate. These processes have entrenched the Narmada's antecedent drainage, resisting despite differential uplift rates between flanking blocks.

Lithology and Rift Features

The Narmada River occupies the , a structure formed along the Narmada-Son Lineament, a major east-west trending tectonic feature that bisects the Indian Shield and separates the northern Vindhyan from the southern Satpura-Deccan block. This lineament originated as a weakness zone and has undergone repeated reactivation, including during the and , resulting in horst- morphology with the Narmada flowing in the depressed axis between the elevated Satpura horst to the south and Vindhya horst to the north. The graben's bounding faults are steep, dipping at 70–80°, with cumulative vertical displacements estimated at 1500–1800 meters, facilitating the river's antecedent incision through resistant . Seismic and geophysical profiling reveals a block-faulted crust beneath the , with deep-seated faults extending near the Moho depth, anomalous crustal thickness variations, and evidence of ongoing tectonic activity influencing and . The rift's includes post-Cretaceous disturbances that modified drainage patterns, with the Narmada maintaining its course due to structural control rather than base-level fall alone. Lithologically, the Narmada basin encompasses a stratigraphic sequence spanning to units, dominated by crystalline basement rocks (gneisses, schists, granites) in the upper reaches, overlain by sedimentary covers of the Vindhyan and Satpura supergroups including , shales, and limestones. sediments, such as the Lower Nimar Formation exposed in the , consist primarily of quartzarenites with monocrystalline grains, minor , , rock fragments, and heavy minerals, reflecting fluvial to shallow marine deposition in a tectonically subsiding basin. Deccan Trap basalts cap parts of the upper basin margins, while the central and lower valley features Tertiary- alluvial fills, conglomerates, and like the Formation, comprising fining-upward sequences of pebbly conglomerates, coarse-to-fine , and siltstones derived from local horst erosion. These lithological variations exert causal control on river incision, with the Narmada exploiting weaker sediments in the core while eroding harder and basaltic uplands, producing distinctive gorges and falls such as Dhuandhar. Ongoing continue to influence sediment , with basin fills recording multiple phases of and incision tied to fault movements.

Hydrological Regime

Flow Patterns and Tributaries

The Narmada River's flow regime is characterized by pronounced , driven by the southwest that accounts for approximately 94% of the basin's annual rainfall between and . This results in peak discharges during the monsoon period, with high flows constituting 70-90% of the annual total volume. The average annual discharge at downstream locations, such as near the , is about 41.3 billion cubic meters (km³). In the non-monsoon seasons, flows diminish significantly but remain perennial due to contributions from in the river's deep aquifers, primarily within basaltic and sedimentary formations. Streamflow data from gauging stations like and indicate consistent interannual variability, with trends analyzed over periods such as 1980-2023 showing influences from rainfall patterns and changes. The river's westerly trajectory through the Narmada Rift facilitates a relatively straight and efficient flow path, with occasional multi-channel bedrock configurations in downcutting reaches enhancing during high flows. The Narmada is augmented by 41 notable tributaries, with left-bank (southern, ) streams generally larger and contributing more runoff due to steeper gradients and higher rainfall catchments compared to right-bank (northern, ) ones. Major left-bank tributaries include the Burhner (length 248 km), Banjar (286 km), Sher (497 km catchment influence), Shakkar (545 km influence), Dudhi, Tawa—the longest at 229 km and joining at Bandrabhan near —and others like Ganjal and Kundi. Right-bank tributaries are shorter, such as the Hiran, Barna, Orsang, Kolar, and Tendoni, draining less voluminous areas. These tributaries collectively drain sub-basins that enhance the main stem's discharge, particularly during monsoons, with the providing the most significant augmentation upstream of major reservoirs.

Water Availability and Seasonal Variations

The Narmada River's water availability is characterized by extreme seasonal fluctuations, dominated by the southwest (June to early ), which delivers approximately 94% of the basin's annual rainfall and drives peak discharges representing 70% to 92% of the total annual flow. The basin's average annual potential stands at 45.64 billion cubic meters (BCM), with utilizable resources estimated at 34.50 BCM, though realized mean annual flows have trended lower in recent decades, averaging around 34.72 to 40.60 BCM depending on the observation period. These variations stem from the basin's , where intense rainfall over the upper catchment generates high-velocity flows, while and limited sustain minimal baseflows elsewhere. In the non-monsoon seasons—post-monsoon (), winter ( to ), and pre-monsoon summer ( to May)—discharge drops sharply to 8% to 30% of annual totals, often approaching environmental minimums of around 361.5 cubic meters per second (m³/s) at gauged sites, equivalent to roughly 30% of mean annual runoff to maintain ecological functions. Dry-season flows rely predominantly on subsurface contributions and sporadic thunderstorms, resulting in reduced water depths and velocities that constrain , withdrawals, and aquatic habitats, particularly in the middle and lower reaches where operations can further attenuate releases. Interannual variability, influenced by El Niño-Southern Oscillation patterns and land-use changes, has shown declining trends in over the past four decades, exacerbating dry-season scarcity amid stable or slightly increasing in some sub-basins.

Cultural and Religious Significance

Mythological Origins and Deity Status

In Hindu tradition, the Narmada River is personified as a , revered as the daughter of Lord , with her origin traced to divine emanation from his body. According to accounts in the , such as the , Narmada emerges from (an aspect of Shiva) as a redeemer from worldly existence, originating from his perspiration during intense penance on Mount Riksha, as described in the Rewa Khand. Alternative legends attribute her birth to a drop of Shiva's sweat while he performed the cosmic dance on the hills or during , symbolizing her emergence as a purifying force to cleanse the sins of celestial beings amid battles with demons. As Narmada Devi, the river goddess embodies benevolence, purity, and maternal compassion, often depicted as slim and beautiful, evading marriage proposals from gods and demons to maintain her eternal virginity, earning her the epithet "" or Rewa (the flowing one). This autonomy underscores her status as one of the holiest , comparable to the , where even the sight (darshan) is believed to purify the soul and grant liberation, surpassing the need for ritual immersion. Her waters are held effective against ailments like snakebites, linking her to Naginis (serpent deities) in texts like the , reinforcing her role as a protector and healer. The deity's annual birth celebration, Narmada Jayanti, falls on the of Magha (typically ), commemorating her descent to earth on Shiva's command from the source, highlighting her integral place in Shaivite devotion and the river's sanctity across the three worlds as the purest among rivers. Devotees offer chunari ( cloth) to her as a symbol of gratitude, reflecting legends of her devotion to despite unfulfilled longing for union with him.

Sacred Sites and Practices

The Narmada River hosts several sacred sites revered in , primarily dedicated to and the river's deity status as a purifying force. , the river's source in Madhya Pradesh's , features the Narmada Udgam Temple where devotees perform rituals at the kund (pool) from which the river emerges, believing immersion cleanses sins due to its origin as one of seven holy rivers. Nearby, the Kapildhara and Sati Kund sites attract pilgrims for ablutions and offerings, attributing sanctity to ancient legends of sage Kapila's . Omkareshwar, located on an island shaped like the sacred syllable "Om" in the Narmada's flow in Madhya Pradesh, enshrines a Jyotirlinga dedicated to Shiva, drawing worshippers for darshan (viewing the deity) and riverbank rituals. The temple complex, dating to medieval reconstructions with Chalukya origins around the 11th century, involves practices like pouring water over the lingam and circumambulating the island via ghats and bridges. Adjoining Mamleshwar Temple on the mainland reinforces Shiva's dual presence, with devotees reciting hymns linking the site's geometry to cosmic symbolism. Maheshwar in features ghats and temples like Kashi Vishwanath along the riverbanks, established under 18th-century Holkar patronage, where rituals include evening aarti (lamp offerings) to honor the river's benevolence. Further downstream, Shulpaneshwar in hosts a temple and for ritual bathing and meditation, tied to (shulpa) in local lore. Common practices at these sites emphasize the Narmada's purifying waters, with bathing believed to absolve sins based on scriptural references to its divine emergence from 's penance. Devotees offer chunari (red cloth) to the river personified as a , seeking blessings for prosperity and protection, a custom rooted in tantric traditions. Banalingas, smooth pebbles from the riverbed resembling lingams, are collected for home worship, valued for their natural formation without human carving. These rituals, performed year-round but peaking during festivals like Shivratri, underscore empirical observations of the river's consistent flow aiding spiritual immersion.

Pilgrimages Including Narmada Parikrama

The Narmada Parikrama is a revered Hindu pilgrimage entailing the clockwise circumambulation of the Narmada River by traversing both its banks from the source at to the near and returning via the opposite bank. This practice, initiated by the Saptarishis according to tradition, underscores the river's unique status as the only major waterway in fully encircled in this manner. The journey covers approximately 2,624 kilometers, reflecting the river's 1,312-kilometer length doubled with crossings and detours along the terrain. Traditionally performed barefoot on foot without vehicular aid, the demands pilgrims subsist on , carry minimal possessions, and uphold rigorous mental purity through continuous chanting and . The prescribed duration spans three years, three months, and thirteen days, aligning with three annual cycles excluding the monsoon season when paths become impassable. Devotees believe completing it grants , liberation from the cycle of rebirth, equivalent in merit to bathing in all sacred rivers or circumambulating every tirtha, as the Narmada—viewed as Shiva's manifestation—purifies sins merely by sight or remembrance. Key rituals include daily bathing in the river for purification, worship of banalingas (river-smoothed stones symbolizing ), and darshan at prominent shrines such as the Narmada Kund at , the Omkareshwar Jyotirlinga island temple, and the ghats of , where ancient rituals persist. The pilgrimage integrates diverse cultural encounters, from tribal hamlets to historic forts, fostering an inner transformation reported by participants as profound self-discovery amid physical hardship. Beyond the full parikrama, shorter pilgrimages along the Narmada include localized yatras, such as the Panchkoshi circuit around Omkareshwar encompassing five sacred kos (about 15 kilometers) of temples and bathing sites, or annual Narmada Jayanti processions celebrating the river's emergence, drawing thousands for aartis and communal feasts at riverbanks. These practices, rooted in references to the river's sanctity, maintain the Narmada's role as a living in Hindu devotion, though modern adaptations like vehicle-assisted tours have shortened durations to months for broader accessibility.

Ecology and Biodiversity

Native Flora and Fauna

The Narmada River basin encompasses tropical dry deciduous forests as the predominant vegetation type, particularly in the central and western regions spanning Madhya Pradesh and Gujarat, where teak (Tectona grandis) dominates alongside species like Lagerstroemia parviflora and other hardwoods adapted to seasonal monsoons and dry periods. These forests cover approximately 32.88% of the basin area, supporting riparian zones with emergent aquatic plants and gallery forests that stabilize riverbanks and contribute to hydrological balance. Terrestrial fauna in the basin includes 76 mammal species, notably the Bengal tiger (Panthera tigris tigris), with the region hosting 17% of the global wild tiger population across protected areas like Kanha Tiger Reserve in the upper catchment. Other characteristic mammals comprise Indian leopards (Panthera pardus fusca), sloth bears (Melursus ursinus), and ungulates such as sambar deer (Rusa unicolor) and chital (Axis axis), which thrive in the dry deciduous habitats influenced by the river's seasonal flooding. Avian diversity reaches 276 species, including hornbills and eagles, though no bird species are strictly endemic to the ecoregion. Aquatic fauna is dominated by freshwater fish, with surveys documenting 84 species across 23 genera, primarily in the orders (39.8% of diversity, including Tor spp. and carps like Catla catla), (47 species), and Siluriformes (32 species). Among these, five species are endemic to , such as Glyptothorax lonah and Mystus montanus, while the river also supports macroinvertebrates like Ephemeroptera (17 species across 6 families) and assemblages indicative of varied flora. Threats from and have reduced populations of migratory species like major carps, yet the basin retains high ichthyofaunal richness compared to fragmented Indian rivers.

Environmental Degradation and Conservation

The Narmada River basin has experienced significant primarily from dam construction, , , and untreated sewage discharges. Large-scale projects like the have submerged over 13,000 hectares of forest land, leading to and for species in the riparian zones. Illegal along the riverbed and foreshore has accelerated , increased , and disrupted aquatic ecosystems, contributing to the river's reduced flow capacity in downstream areas. Pollution from municipal sewage and industrial effluents has elevated (BOD) levels beyond safe limits in several stretches, as reported by the Madhya Pradesh Pollution Control Board, impairing and harming populations. Heavy metal contamination in sediments and shows seasonal fluctuations, with higher concentrations during monsoons due to runoff from degraded catchments, posing risks to aquatic life and human health via . In the upper catchment, affects approximately 23% of global land resources analogously, driven by rates exacerbated by and forest fires, resulting in that reduces reservoir storage capacity. Conservation initiatives include riparian zone restoration efforts by organizations like India, focusing on revegetation of catchment areas, control, and mitigation through improved sanitation. The Narmada Valley Dry Deciduous Forests ecoregion encompasses 17 protected areas covering about 7,600 km², aimed at preserving amid threats from forest conversion. Community-led projects emphasize protecting against , , and wildfires, while national programs under the National River Conservation Plan support to reduce organic loads. Despite these measures, ongoing pressures from development projects challenge the of these efforts, with calls for stricter enforcement against illegal activities to maintain ecological integrity.

Historical and Archaeological Record

Prehistoric Human Settlements

The Narmada Valley preserves extensive evidence of human occupation, primarily through tool assemblages scattered along the riverbanks and tributaries in , particularly in . These sites, dating from the Early to Middle Pleistocene (approximately 1.5 million to 100,000 years ago), indicate repeated hominin exploitation of the valley's resources, including and for bifacial handaxes, cleavers, and scrapers adapted to local raw materials. Excavations and surveys have identified over 18 new localities in and Narmadapuram districts alone, with artifacts concentrated north of the river, likely due to geological exposure and proximity to Vindhyan foothills providing vantage for hunting and water access. Key sites such as Pandado, Tikoda, and Patpara yield asymmetrical bifaces and flake tools, suggesting mobile groups adapted to the valley's environments during wetter climatic phases. A landmark discovery underscoring early hominin presence is the partial cranium of Homo erectus (or archaic Homo sapiens), known as Narmada Human, unearthed in 1982 at Hathnora near the river terraces in Sehore district by palaeontologist Arun Sonakia of the Geological Survey of India. The fossil, embedded in gravel conglomerates of the Surajkund Formation, is associated with fauna indicative of a Middle Pleistocene age, estimated at 500,000 to 600,000 years based on co-occurring mammalian remains like Stegodon and Hippopotamus. This specimen represents the earliest documented hominin skeletal evidence in the Indian subcontinent, with morphological traits such as a low vault and robust brow ridges aligning with African and Asian H. erectus populations, implying migration routes through the valley. Associated Middle Paleolithic tools, including Levallois flakes, from nearby strata suggest behavioral continuity into later phases, though direct stratigraphic linkage remains debated due to fluvial reworking. The valley's role as a hominin corridor is further evidenced by faunal assemblages from sites like Devakachhar, yielding Pleistocene fossils alongside stone tools, pointing to systematic scavenging or settlements sustained by the river's perennial flow and adjacent forests. While erosion and modern development threaten these open-air sites, their distribution reflects strategic occupation of bends and escarpments for , with no permanent structures but recurrent tool-making loci indicating semi-sedentary exploitation patterns. Later prehistoric phases transition to microlithic evidence around 10,000 years ago in the region (e.g., ), but dominance underscores the Narmada's primacy in early human dispersal across peninsular .

Ancient Trade and Cultural Sites

Bhagatrav, situated near the estuary of the Narmada and Kim rivers, functioned as a protohistoric trading outpost during the Harappan period (circa 2600–1900 BCE), with excavations revealing a 2-meter cultural deposit containing beads, chert blades, and iron , suggestive of involvement in raw material procurement and coastal exchange networks. , another Harappan-era station at the Narmada mouth, supported late-phase maritime activities, linking the riverine interior to broader coastal trade routes. Bharuch (ancient Barygaza), positioned on the northern bank of the Narmada estuary, emerged as a key early historic port (from circa 200 BCE onward), evidenced by protohistoric settlements, jetty remnants, and artifacts indicating shipbuilding and commerce with Mediterranean traders as described in the ; medieval layers further attest to Arab trade connections. The valley's geological resources, including and chert, were exported upstream to Indus centers like and for bead production and tool-making. Upstream Chalcolithic settlements at and (circa 1900–1200 BCE), associated with the , exhibit fortified structures, distinctive , and a sequence of occupation extending into the and early historic periods, reflecting enduring cultural hubs with potential ties to regional resource flows along the Narmada. These sites yielded evidence of and material continuity, underscoring the river's role in sustaining prehistoric communities amid broader Deccan interactions.

Developmental Utilization

Irrigation Networks and Hydroelectric Capacity

The irrigation networks of the Narmada River derive primarily from the multipurpose dams under the Narmada Valley Development Authority, utilizing the basin's estimated utilizable surface water of 34,500 million cubic meters annually. The Sardar Sarovar Dam in Gujarat anchors the primary network via the Narmada Main Canal, the world's largest lined irrigation canal at 532 km long with a head regulator capacity of 1,133 cumecs (40,000 cusecs), tapering to 73 cumecs downstream. This canal system, extending 485 km in Gujarat and 75 km into Rajasthan, supports irrigation for 1.905 million hectares, including command areas in arid regions through branches and distributaries. Upstream, the Indira Sagar Dam in features canal networks irrigating 123,000 hectares directly, with an annual irrigation potential of 265,000 hectares via left and right bank s. Additional networks from projects like Bargi and Tawa dams contribute smaller irrigated areas, but the Sardar Sarovar and Indira Sagar systems dominate, with total live storage from completed projects at 17,806 million cubic meters enabling regulated flows for . These networks prioritize perennial canal irrigation, reducing dependency on variability through reservoir releases timed for cropping seasons. Hydroelectric capacity in the Narmada basin totals 3,498.5 MW from installed projects as of recent assessments. The provides 1,450 MW, shared among (57%), (27%), and (16%), with riverbed and canal-head powerhouses utilizing Francis turbines for baseload and peak generation averaging 3,500 million units yearly. The Indira Sagar Dam adds 1,000 MW via six 200 MW reversible pump-turbines, yielding 2,698 million units annually in stage-I operations. Smaller installations, such as the 90 MW at Omkareshwar, supplement the grid, with overall basin generation supporting industrial and domestic needs while minimizing reliance through run-of-river and storage schemes.

Key Infrastructure Projects

The Narmada Valley Development encompasses multiple dams and associated infrastructure aimed at harnessing the river's water for , hydroelectric power, and drinking water supply across , , and . Key components include major dams such as Sardar Sarovar, Indira Sagar, and Omkareshwar, which form the backbone of the basin's developmental utilization. These projects, coordinated by the Narmada Control Authority, involve structures designed to store vast reservoirs and generate significant power, with capacities ranking among the world's highest for flood management. Sardar Sarovar Dam, located in near Kevadiya, stands at a height of 163 meters and spans 1,210 meters in length, featuring a gross storage of 9.5 billion cubic meters. Constructed starting in 1987 and reaching full height in 2017, it supports for over 1.8 million hectares and boasts an installed hydroelectric capacity of 1,450 megawatts through riverbed and canal-head powerhouses. Its spillway discharges up to 30.7 lakh cubic feet per second, ranking third globally. Indira Sagar Dam in Madhya Pradesh's is a 92-meter-high, 653-meter-long gravity structure completed in 2005, providing to 1,230 square kilometers annually. The associated powerhouse, commissioned in 2004, has generated over 2,698 gigawatt-hours of electricity, with the reservoir enabling multipurpose uses including flood control. Omkareshwar Dam, situated upstream in , features a 73-meter-high concrete gravity dam completed between 2004 and 2006, with a length of 949 meters and a gross storage capacity of 987 million cubic meters. It generates 520 megawatts of power and supports networks, forming a critical link in the upper basin's chain. Additional includes the Maheshwar Hydroelectric Project, under development with a 400-megawatt capacity, and extensive canal systems like the Narmada Main Canal, which distribute water for agricultural enhancement in . These projects collectively aim to exploit the river's 75 billion cubic meters annual flow, though implementation has faced delays and inter-state coordination challenges.

Quantifiable Economic Benefits

The Sardar Sarovar Project has established an irrigation network capable of annually supplying water to 1.792 million hectares in and 0.246 million hectares in , facilitating increased in arid regions through the 532-kilometer Narmada Main , the world's largest concrete-lined by volume capacity of 1,133 cubic meters per second. This infrastructure supports multi-crop cultivation, with command areas encompassing drought-prone districts and contributing to 's agricultural output by enabling stable yields of cash crops like and groundnut. Hydroelectric generation from the provides 1,450 megawatts of installed capacity, comprising 1,200 MW from the riverbed powerhouse and 250 MW from the head powerhouse, supplying firm power to , , , and while reducing reliance on thermal sources and associated fuel costs. Complementing this, the Indira Sagar Project delivers 1,000 MW of with an annual generation of 2,698 million units, powering industrial and domestic needs in . Across the Narmada basin, these projects have created an ultimate irrigation potential exceeding 4 million hectares when combining major schemes, translating to enhanced food grain production estimated at additional millions of tonnes annually based on pre-project assessments of yield increments from assured . Economic returns are evidenced by internal rates of return projected at 12-18% for similar large-scale irrigation-hydropower initiatives, driven by causal links between and agricultural GDP contributions in beneficiary states.

Controversies and Impacts

Population Displacement and Rehabilitation Outcomes

The (SSD) and associated Narmada basin projects, including the Indira Sagar Dam, have displaced an estimated 40,000 to 42,000 families primarily from 245 villages in , , and , according to official figures from project authorities; these numbers encompass direct submergence but exclude broader project-affected persons such as those impacted by canals or downstream effects. Activist groups, including the (NBA), assert higher totals of 90,000 to 100,000 families when accounting for unenumerated marginal farmers, landless laborers, and ecological refugees, a discrepancy attributed to methodological differences in surveys and potential undercounting by state agencies to streamline approvals. The majority of displacees are indigenous communities reliant on forest-based livelihoods, with submergence affecting over 37,000 hectares of land across the basin. Rehabilitation under the 1979 Narmada Water Disputes Tribunal Award mandated "land for land" compensation, cash equivalents, and civic infrastructure like schools and roads, with providing irrigated plots while and initially favored monetary payouts; the Narmada Control Authority (NCA) monitors compliance through subgroups and field reports. By July 2024, 32,552 families had received resettlement packages or extensions across the three states, including house plots, agricultural land, and subsistence grants, per parliamentary disclosures. 's Sardar Sarovar Narmada Nigam Ltd claims an "excellent" policy implementation, relocating thousands to canal-adjacent sites with enhanced water access. Outcomes remain disputed, with official NCA progress reports indicating substantial completion but persistent gaps: as of 2023, over 17,000 families awaited full rehabilitation amid rising levels to 138.5 meters, exacerbating vulnerabilities in villages like Katnera, where oustees received no prior acknowledgment or aid despite submergence. Empirical assessments reveal mixed socioeconomic results; resettlements often yielded agricultural gains via , with some studies deeming them a "success story" for restoration, yet upstream displacees frequently faced barren lands, incomplete amenities, and net impoverishment, including a reported drop in for tribal groups due to lost commons and cultural ties. Independent reviews, such as the World Bank's 1992 Morse Commission, highlighted early failures in baseline data and consultation, contributing to ongoing litigation, though rulings in 2000 and 2017 affirmed project viability conditional on accelerated rehab. NBA-led surveys document higher rates of debt and migration among oustees, contrasting government claims, underscoring implementation biases in state-level execution where lagged due to fiscal and land constraints.

Environmental and Social Criticisms

The on the Narmada River has faced criticism for submerging approximately 37,000 hectares of land across , , and , including over 13,000 hectares of , which opponents claim disrupts ecosystems and reduces in the region. Independent reviews have noted that the environmental impacts, including habitat loss for , may exceed initial predictions due to discrepancies in hydrological data and inadequate mitigation planning. Downstream effects include reduced river flow, leading to diminished fisheries, sediment trapping that exacerbates , and potential groundwater salinization from sea ingress up to 40 km inland. Social criticisms center on the displacement of an estimated 40,000 to 70,000 people, predominantly (tribal) communities reliant on forest-based livelihoods, with reports indicating suboptimal rehabilitation outcomes such as reduced land holdings, fewer livestock, and limited post-resettlement, resulting in no significant income gains for affected families. The separation of forest-dwelling groups from their traditional surroundings has been highlighted as exacerbating cultural and economic vulnerabilities, compounded by allegations of corruption in compensation processes and concerns during evictions. Across the broader Narmada Valley Project, which encompasses multiple dams, total displacement affects over 200,000 individuals, many from marginalized sections, with critics arguing that legal mandates for rehabilitation were inconsistently applied.

Activist Campaigns and Empirical Rebuttals

The (NBA), established in 1985, emerged as the primary activist movement opposing large-scale dam construction on the Narmada River, particularly the (SSD) and upstream projects like Narmada Sagar. Led by figures such as and , the campaign mobilized tribal communities, farmers, and environmentalists through non-violent methods including (protests involving fasting and immersion in the river), rallies, and legal petitions to the . NBA's international advocacy highlighted alleged failures in displacement rehabilitation and environmental safeguards, culminating in the World Bank's 1993 withdrawal of funding for SSD following the Morse Commission's independent review, which identified deficiencies in resettlement planning and ecological assessments. Domestic efforts persisted, with over 1,000 protesters rallying at Kasrawad Bridge in September 2019 against reservoir filling, claiming inadequate prior notification to affected populations. Campaigns asserted that SSD would displace up to 200,000 people across Narmada projects without viable rehabilitation, submerge fertile lands and forests, and yield minimal net benefits due to overoptimistic projections of and power output. Activists, often drawing from tribal narratives of cultural loss, secured temporary halts via orders, such as the Supreme Court's 1994 stay on construction pending rehabilitation verification, though a 2000 ruling permitted resumption with conditional monitoring. Empirical data from the Narmada Control Authority (NCA) and project authorities indicate that rehabilitation for SSD-affected families—numbering approximately 40,000 primarily in —has been substantially completed, with land-for-land compensation, housing, and civic amenities provided under policies mandating equivalent or superior facilities. The NCA's Rehabilitation Sub-Group verified compliance before approving the dam's final height increase to 163 meters in 2017, enabling full reservoir capacity. Independent economic analyses, including those comparing resettled oustees to non-displaced neighbors, have found that while initial disruptions occurred, long-term access to irrigated lands and often resulted in improved agricultural yields and household incomes for many relocatees, countering blanket claims of uniform impoverishment. On environmental and developmental fronts, SSD has irrigated 1.792 million hectares in and 0.246 million hectares in , bolstering crop production in arid regions and generating 1,450 MW of hydropower shared among riparian states (57% , 27% , 16% ). These outcomes have yielded positive externalities such as and reduced pumping costs for adjacent farms, with studies documenting net gains in farm output despite activist projections of diminished returns from or . Delays from litigation, exceeding two decades, inflated costs but did not negate verifiable benefits, including moderation and to over 700 villages, as tracked by state irrigation departments—evidence that prioritizes causal links between storage infrastructure and regional over unsubstantiated submersion critiques. Source biases in activist narratives, often amplified by NGOs with limited on-ground verification, have been noted in judicial reviews emphasizing data-driven monitoring over anecdotal reports.
