Dams are the perfect examples of architectural and civil engineering marvels. Tough, strong, and extremely durable, they comprise colossal concrete walls and unpenetrable structures. Generating huge amounts of hydroelectricity, dams are inevitable for irrigation, industrial usage, and domestic purposes.
In India, there’s a huge potential for construction of massive dams, owing to the country’s abundant water resources and multiple rivers. After independence, India has constructed several dams and water reservoirs, with approximately 4300 already-constructed large dams. Moreover, there are several projects in the pipeline. They also attract many tourists throughout the year.
Satluj Jal Vidyut Nigam (SJVN), Bharat Heavy Electricals Limited (BHEL), and National Hydroelectric Power Corporation (NHPC) are the pioneering organizations who handle the dam construction business in the country. If you did not know already, Tehri Dam is the eighth highest dam in the world. Additionally, the Idukki dam is the first Indian arch dam that was built across the Periyar river in Kerala.
It is, in fact, the largest arch dam in Asia. Again, the Grand Anicut of Kallanai, which is constructed on the Cauvery River in Tamil Nadu, is the oldest dam in the world. Indira Sagar Dam is known to be the largest reservoir in India.
Below, we have compiled a list of the 10 largest dams in the country.

Sardar Sarovar Dam aka Narmada Dam is the most massive project that has been built or will be constructed on the Narmada river. With a height of 163 meters and length of 1210 meters, it is located in Gujarat. It plays a vital role in providing water to the arid regions of Kutch and Saurashtra, which are often prone to severe and frequent droughts.
This dam is considered to be vision of India’s first deputy prime minister Sardar Vallabhbhai Patel. The dam’s foundation was first laid out by India’s first Prime Minister Pandit Jawaharlal Nehru on 5th April, 1961.
Sardar Sarovar Dam has the capacity to generate up to 200 MW of power and offers its benefits to the states of Gujarat, Madhya Pradesh, Maharashtra, and Rajasthan. It features a reservoir capacity of 7,701,775 acre·ft.
“Four crore Gujaratis will get drinking water and 22,000 hectares of land will be irrigated,” claimed union minister Nitin Gadkari on the benefits of the project.
Hirakud Dam (Odisha) Hirakud-Dam
