Key Takeaways

  • Sardar Sarovar Dam is built across the sacred Narmada River (largest west-flowing river in Peninsular India) at Ekta Nagar (Kevadia) in Narmada district, Gujarat. It is the cornerstone of the Narmada Valley Development Project.
  • It is the second-largest concrete gravity dam in the world by volume of concrete used (after Grand Coulee Dam, USA) and the third-highest concrete gravity dam globally. Height: 138.68 m (455 ft); Length: 1,210 m (3,970 ft); 30 radial spillway gates.
  • Total installed power capacity: 1,450 MW — River Bed Power House (1,200 MW, underground, 6 × 200 MW reversible Francis turbines) + Canal Head Power House (250 MW, 5 × 50 MW Kaplan turbines).
  • Power is shared among three states as per NWDT award: Madhya Pradesh 57%, Maharashtra 27%, Gujarat 16%.
  • The Narmada Main Canal is 458 km long in Gujarat + 74 km in Rajasthan. It irrigates over 1.8 million hectares in drought-prone Saurashtra, Kutch, and southern Rajasthan, and supplies drinking water to over 9,000 villages and 135 urban centres.
  • The project has been at the centre of the Narmada Bachao Andolan (NBA) led by Medha Patkar and Baba Amte. The 2000 Supreme Court judgment allowed construction with parallel rehabilitation of displaced families.

Introduction & Multi-Purpose Significance

The Sardar Sarovar Dam on the Narmada River is one of the most ambitious, controversial, and transformative water resource projects in independent India. Conceived originally by Sardar Vallabhbhai Patel, it has become the lifeline for drought-prone regions of Gujarat, parts of Rajasthan, and has significantly contributed to the power needs of western and central India.

As the second-largest concrete gravity dam in the world by volume, it stands as a symbol of both engineering achievement and the complex socio-environmental debates surrounding large dams in India. For competitive exams, it is a high-yield topic covering interstate river disputes, irrigation geography, power sharing, and environmental movements.

📌 Exam Pointer:

Sardar Sarovar is repeatedly asked under themes like “Largest concrete gravity dams”, “Narmada Bachao Andolan”, “Interstate water disputes”, “Narmada Main Canal command area”, and “Supreme Court judgments on development vs environment”.

Location & The Sacred Narmada River

The dam is located at Ekta Nagar (formerly Kevadia) in Narmada district of Gujarat. It is built across the Narmada River, revered as one of the holiest rivers in India and the largest west-flowing river of Peninsular India.

The Narmada originates from the Amarkantak plateau in Madhya Pradesh and flows westward between the Vindhya and Satpura ranges before emptying into the Gulf of Khambhat in Gujarat. The Sardar Sarovar is the terminal major dam on this river and the key structure of the Narmada Valley Development Project.

💡 Memory Trick:

“Sardar Sarovar = Sardar (Patel’s vision) + Sarovar (reservoir) on Narmada = Lifeline for Saurashtra, Kutch & Rajasthan”.

Physical Specifications & Concrete Gravity Dam

Sardar Sarovar is a massive concrete gravity dam. It ranks as the second-largest concrete gravity dam in the world by volume of concrete (after the Grand Coulee Dam in the USA) and the third-highest concrete gravity dam globally.

HEIGHT
138.68 m
(455 ft) from deepest foundation
LENGTH
1,210 m
(3,970 ft) across Narmada

The dam is equipped with 30 massive radial spillway gates to safely pass heavy flood discharges during the monsoon. Its final height was achieved after decades of legal and political processes.

Power Generation & Interstate Sharing Formula

The Sardar Sarovar Project has a total installed hydroelectric capacity of 1,450 MW, generated from two powerhouses:

  • River Bed Power House (RBPH): 1,200 MW — Located underground, consists of 6 × 200 MW reversible Francis turbines. It utilizes the main river fall.
  • Canal Head Power House (CHPH): 250 MW — Located at the head of the main canal, consists of 5 × 50 MW conventional Kaplan turbines.

Interstate Power Sharing (as per Narmada Water Disputes Tribunal award):

  • Madhya Pradesh: 57% (largest share as most of the catchment lies in MP)
  • Maharashtra: 27%
  • Gujarat: 16%
📌 Exam Pointer:

Remember the power sharing percentages: MP 57%, Maharashtra 27%, Gujarat 16%. Questions on interstate sharing of Sardar Sarovar power are common in UPSC and State PSC exams.

The Narmada Main Canal & Irrigation Network

The irrigation component of the Sardar Sarovar Project is one of the largest water conveyance systems ever built. The Narmada Main Canal is a completely lined gravity contour canal that stretches 458 km across Gujarat up to the Rajasthan border and extends another 74 km into Rajasthan.

It irrigates over 1.8 million hectares of land, bringing water to the chronically drought-prone regions of Saurashtra, Kutch in Gujarat, and the arid districts of Barmer and Jalore in Rajasthan. In addition, the project supplies drinking water to more than 9,000 villages and 135 urban centres across western India.

💡 Memory Trick:

“Narmada Main Canal = 458 km (Gujarat) + 74 km (Rajasthan) = Water for Saurashtra, Kutch & Barmer-Jalore”.

Historical Timeline & Political Context

  • 1946 — Project first conceptualized by Sardar Vallabhbhai Patel to address water scarcity in western India.
  • 5 April 1961 — Foundation stone laid by Prime Minister Jawaharlal Nehru.
  • 1969 — Narmada Water Disputes Tribunal (NWDT) constituted by the Central Government to resolve sharing disputes between Gujarat, Madhya Pradesh, and Maharashtra.
  • 1979 — NWDT gave its final award, laying down parameters for dam height and water/power sharing.
  • 17 September 2017 — Dam dedicated to the nation at its final full height by Prime Minister Narendra Modi.

Narmada Bachao Andolan & Supreme Court Judgment

The Sardar Sarovar Dam became the focal point of one of India’s most significant environmental and human rights movements — the Narmada Bachao Andolan (NBA), launched in the mid-1980s.

Led by social activists Medha Patkar and Baba Amte, the movement protested against the large-scale submergence of forests and fertile lands in upstream Madhya Pradesh and the inadequate rehabilitation and resettlement (R&R) of tens of thousands of displaced tribal (Adivasi) families.

In the landmark 2000 judgment in Narmada Bachao Andolan vs. Union of India, the Supreme Court of India allowed the construction of the dam to continue, but with the strict condition that rehabilitation of displaced families must proceed pari passu (hand-in-hand) with every increase in dam height.

⚠️ Common Confusion:

The NBA is often asked as a case study of development vs. displacement. Remember the key outcome: Supreme Court permitted construction but mandated parallel rehabilitation. It did not stop the dam.
