According to the Central Water Commission (CWC) of India’s Union Ministry of Water Resources, India has 5701 large dams. In addition to these large dams, India has a large number of under construction large dams. Maharashtra, with 2354 large dams, is the state with the highest number of large dams in India. However, the tallest dam of India is situated in the state of Uttarakhand. The Tehri dam situated on Bhagirathi River is the tallest and highest dam in India. The height of the Tehri dam is 260.5 meters and it is 575 meters long.
Tehri dam: How tall is the tallest dam of India?
The tallest as well as the highest dam of India, Tehri dam, is exactly 260.5 (855 ft) meters tall. Tehri dam is a multi-purpose rock and earth-fill embankment dam on the confluence of Bhagirathi and Bhilangana Rivers and is situated in Tehri Garhwal district of Uttarakhand. The work to construct Tehri dam was started in the year 1978 and was completed in 2006 when its first unit was commissioned. The Tehri dam was built by THDC India Ltd.
The construction of the tallest dam of India was not an easy task. Even it raised environmental concerns due to its situation in the fragile ecosystem of the Himalayan foothills. Since Tehri dam is located 7.5kms above the Central Himalayan Seismic Gap, which is a major geologic fault zone, there have been concerns regarding the dam’s safety. Tehri hills are known for landslides. It also creates fear in the mind of the people living in nearby areas.
India is one of the countries having sufficient hydroelectric potential. There are many rivers which are perennial and carry a large amount of water throughout the year. Due to this hydroelectric potential, India has built thousands of dams on rivers. India has a hydroelectric potential of about 1, 45, 000 MW with a 60% load factor. These dams also provide much-needed relief to the farmers by providing timely water for irrigation purposes. The dams built in India are also used to supply clean drinking water to millions of people.
