 To the south west Malwa plateau, the dissected hill
tracts culminate in the Mathwar hills, located
in Alirajpur district of Madhya Pradesh.
 Below these hills Narmada river flows through a
long, terrific gorge.
 This gorge extends into Gujarat where the river is
tapped by the Sardar Sarovar dam.

6. HISTORY OF SARDAR SAROVAR DAM
The plan for harnessing the river for irrigation and power generation in the Narmada basin was initiated in 1946.
Seven projects including the Bharuch project were identified during the initial Survey and 4 projects Bharuch
(Gujarat), Bargi, Tawa and Punasa in Madhya Pradesh were given top priority for investigation. After the
completion of investigation, the proposed dam at Gora in Gujarat with the full reservoir level (FRL) 161 ft (49.08m)
was selected and the foundation stone was laid by late Prime Minister, Pandit Jawaharlal Nehru on 5th April, 1961.
However as more detailed, modernized contour sheets from the Survey of India were available thereafter,
possibility of raising the height of the dam for optimum utilization of water was considered.
In 1964, to resolve the dispute about sharing of the Narmada Waters between the Governments of Gujarat and
Madhya Pradesh, the Government of India appointed an expert committee under the Chairmanship of late Dr.
Khosla which recommended a higher dam with FRL 500 ft (152.44m) in 1965. However, Govt. of M.P. was not
agreeable to development of Narmada water as per Khosia Committee report and hence the Narmada Water
Dispute Tribunal (NWDT) was constituted by the Government of India in October 1969, under the Inter State River
Water Disputes Act, 1956. NWDT gave its final award in December 1979.

7. BACKGROUND OF SARDAR SAROVAR DAM
•The Sardar Sarovar Project was the brainchild of Sardar Vallabh Bhai Patel (India’s first deputy Prime
Minister) in the view to arrest the excess flow of water from Narmada river to the Arabian sea.
•Pandit Jawaharlal Nehru had laid the foundation stone for the project in 1961. However, the construction of
the project was started only in 1987. For information regarding Pt. Jawaharlal Nehru, visit the link provided
here.
•The Supreme Court stalled the project in 1995 as the project was a controversial one because many people
objected to the construction of the dam citing environmental issues and the displacement of people.
•The Narmada Bachao Andolan was formed in order to protest against the project.
•In 2000- 2001 the project was revived but with a lower height of 110.64 metres under directions from the
SC, which was later increased in 2006 to 121.92 meters.
•The Project was executed by Gujarat Government’s Sardar Sarovar Narmada Nigam Limited – SSNL.

8. ABOUT SARDAR SAROVAR DAM
•Sardar Sarovar Project is a concrete gravity dam on the Narmada river in
Kevadiya near Navagam, Gujarat.
•It is the second-largest concrete dam in the world in terms of the volume of
concrete used to construct the dam (after the Grand Coulee Dam in the
United States).
•It involves a series of large irrigation and hydroelectric multi-purpose
dams.
•The irrigation benefits accrue to the states of Rajasthan and Gujarat while
the hydroelectric power of the SSP is to be shared by the states of Gujarat,
Madhya Pradesh and Maharashtra. Maharashtra is to get around 57
percent of the electricity produced; Madhya Pradesh will get around 27
percent and Gujarat around 16 percent.
•It was funded by the World Bank through its International Bank for
Reconstruction and Development (IBRD), although it withdrew in 1994.

9. • It is a part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of
large irrigation and hydroelectric multi-purpose dams on the Narmada river.
• The Sardar Sarovar Project includes two powerhouses, the River Bed Power House – RBPH with an installed capacity of
1,200 MegaWatt and the Canal Head Power House with 250 MegaWatt).
• The Narmada Control Authority decided on 17 June 2017 to raise the height of the Sardar Sarovar Dam to its fullest height
163 meter (depth) by ordering the closure of 30 Gates.
• It is the third-highest concrete dam in India with 138.68 metres height.
• The Sardar Sarovar Project was inaugurated in September 2017 by Prime Minister Modi.

12. BENEFITS OF SARDAR SAROVAR DAM
•Unused Water from Narmada river, which would otherwise flow into the sea, is used for serving many dry
towns, villages and districts of Gujarat.
•The project employed about one million people starting from the start to the end of the Sardar Sarovar
project.
•Provided electricity to the unserved regions and also to the farmers.
•Provided water for irrigation and for drinking purposes.
•Around 800,000 hectares of land in Gujarat and approx 2,46,000 hectares of land in Rajasthan are irrigated
by the water of SSD. It is said that it provides drinking water to 131 towns and cities and around 9,633
villages in the four states, mostly the drought-prone areas of Kutch and Saurashtra.
•Provided flood protection to an area of about 30,000 hectares which is prone to the fury of floods.
•Wildlife sanctuaries will also be benefited

14. RESERVOIR OF SARDAR SAROVAR DAM
 The Full Reservoir Level (FRL) of the Sardar Sarovar Dam is fixed at RL 138.68 metres (455 feet). The
Maximum Water Level is 140.21 metres (460 feet.) while minimum draw down level is 110.64 metres
(363 feet.). The normal tail water level is 25.91 metres (85 feet.).
 The gross storage capacity of the reservoir is 0.95 M. ha.m. (7.7 MAF) while live storage capacity is 0.58
M.ha.m. (4.75 MAF). The dead storage capacity below minimum draw down level is 0.37 M. ha. m. (2.97
MAF). The reservoir would occupy an area of 37,000 ha. and would have a linear stretch of 214 kilometer
of water and an average width of 1.77 kilometer.
 The submergence at Full Reservoir Level (FRL) is 37,690 ha. (86,088 acres), which comprises 11,279
ha. agricultural land, 13,542 ha. forests and 12,869 ha. river bed and waste land. In all 245 villages of the
three states viz. 193 Villages of Madhya Pradesh, 33 villages of Maharashtra and 19 villages of Gujarat
are affected. Only 3 villages of Gujarat are fully affected, while the remaining 242 villages are partly
affected. In Madhya Pradesh, out of 193 villages, more than 10% agricultural land will be submerged only
in 79 villages, in 89 villages less than 10% agricultural land or only houses will be submerged under FRL,
due to back water of 1 in 100 years flood. In 25 villages, only Government waste land will be submerged.
