India has several notable gravity dams, primarily located in the states of Himachal Pradesh, Uttarakhand, and Maharashtra. Prominent examples include the Bhakra Dam in Himachal Pradesh, the Tehri Dam in Uttarakhand, and the Koyna Dam in Maharashtra. These dams are strategically built to harness river water for irrigation, power generation, and flood control. Additionally, several other gravity dams can be found throughout the country's river systems, contributing to water management and energy production.

There are many gravity dams constructed of compacted earth. High dams are generally concrete. All dams require a spillway to be safe. The spillway must be armored.
Pandit Jawaharlal Nehru, independent India's first prime minister, referred to dams as the "Temples of Modern India".

Advantage of a gravity dam is that every section will be stable and reliable. An Earth dam can overflow and collapse because of erosion.
At independence, in 1947, there were fewer than 300 large dams in India. By the year 2000 the number had grown to over 4000, more than half of them built between 1971 and 1989. India ranks third in the world in dam building, after US and China. While some of these dams were built primarily for flood control, water supply, and hydroelectric power generation, the primary purpose of most Indian dams remains irrigation.

Nehru called dams 'impotant of modern India' in the sense that he was affirming a commitment to modernisation and socialism in post-Independence India. Whilst temples might be seen as mystical, traditional and ancient, dams signified rationality, progress and modernity.
