HI DIZ IS MOULALI i wanna ppt on nagarjuna sagar dam for the better understanding and helps me to explain to my friends

Nagarjuna Sagar Dam is the world's largest masonry dam built across Krishna River in Nagarjuna Sagar,Nalgonda District of Andhra Pradesh, India. It is downstream to the Nagarjuna sagar reservoir with a capacity up to 11,472 million cubic metres which is the world's largest man-made lake with a concrete wall of 6 ft. thickness. The dam is 490 ft. tall and 16 Km long with 26 gates which are 42 ft. wide and 45 ft. tall.[1]

It is one of the earliest irrigation and hydro-electric projects in India. The dam provides irrigation water to the Nalgonda District, Prakasam District, Khammam District, and Guntur District.The proposal to construct a dam to use the excess waters of the Krishna river was put forward by the British rulers in 1903. Siddeswaram and Pulichintala were identified as the suitable locations for the reservoirs.The dam water was released by the then Prime Minister's daughter, Indira Gandhi in 1967.[5] The construction of the dam submerged an ancient Buddhist settlement, Nagarjunakonda, which was the capital of the Ikshvaku dynasty in the 1st and 2nd centuries, the successors of the Satavahanas in the Eastern Deccan. Excavations here had yielded 30 Buddhist monasteries, as well as art works and inscriptions of great historical importance. In advance of the reservoir's flooding, monuments were dug up and relocated. Some were moved to Nagarjuna's Hill, now an island in the middle of the reservoir. Others were moved to the mainland.The project benefited farmers in the districts of Guntur, Prakasam, Krishna, Nalgonda and khammam. The right canal (a.k.a Jawahar canal) is 203 km long and irrigates 1.113 million acres (4,500 km²) of land. The left canal (a.k.a Lalbahadur Shastri canal) is 295 km long and irrigates 0.32 million acres (800 km²) of land in nalgonda and khammam districts of telangana region. The project transformed the economy of above districts. 52 villages were submersed in water and 24000 people were affected. The relocation of the people was completed by 2007.The hydroelectric plant has a power generation capacity of 815.6 MW with 8 units (1x110 MW+7x100.8 MW). First unit was commissioned on 7 March 1978 and 8th unit on 24 December 1985. The right canal plant has a power generation capacity of 90 MW with 3 units of 30 MW each. The left canal plant has a power generation capacity of 60 MW with 2 units of 30 MW each.

Nagarjuna Sagar, located at a distance of 150 km from Hyderabad, is one of the most prominent Buddhist centers and attractive tourist spots in Andhra Pradesh.Known in ancient days as Vijayapuri, Nagarjunasagar takes its present name from Nagarjuna, one of the most revered Buddhist monks, who governed the sangha for nearly 60 years around the turn of the 2nd century AD. It is also a place of immense archaeological significance & excavations which reveal Nagarjunasagar as a center for the propagation of Buddhist teachings in South India.


nagarjuna dam
One of the early river valley civilizations took birth here. Enthused by the peaceful environs of this place, Buddhists made this land a great hub of learning, setting up one of the four major Viharas here. Further down in history, one of the first Hindu kingdoms of South India, Ikshvakus made this city their capital. Once Vijayapuri, today Nagarjunasagar, this hoary land of antiquity and enligtment, now boasts of the world's tallest masonry dam.

Nagarjuna dam, which was completed in 1966, is 124 metres high and 1 km long has 26 crest gates. The lake, which it straddles, is the third largest manmade lake in the world. 4 kms away from the dam, is the Viewpoint, where a panoramic view of the amazing landscape, is simply a feast to the eyes.

One of the earliest hydro-electric projects of India, the Nagarjunasagar Dam is a symbol of modern India's architectural and technological triumphs over nature.


The relics of Buddhist civilisation dating back to the 3rd Century A.D were excavated here.

The excavated remains of the Buddhist civilization have been reconstructed and are carefully preserved at Nagarjunakonda, a unique Island museum, situated in the midst of the man-made Nagarjunasagar lake.
Constructed In the shape of a Buddhist Vihara, the museum houses a stupendous collection of relics of Buddhist art and culture. Famous relics include a small tooth and an ear-ring believed to be of the Buddha. The main stupa of Nagarjunakonda called Mahachaitya is believed to contain the sacred relics of lhe Buddha. A partly ruined monolithic statue of the Buddha, that's at once a striking-image of peace and poise, is the main attraction at the museum.
The monasteries and chaityas were reconstructed on top of a hill called Nagarjunakonda (konda is the Telugu word for hill), which rises from the middle of the lake. The island takes its name from the Buddhist monk, Nagarjuna, who lived around the turn of the 2nd century AD and was the exponent of the philosophy of sunyata (void). Statues, friezes, coins and jewellery found at the site are housed in a museum on the island and give a fascinating insight into the daily lives of this ancient Buddhist centre. Earlier it used to be known as Vijayapur. The site was discovered in 1926. Subsequent excavations, particularly in the '50s and '60s, have unearthed the remains of stupas, viharas, chaityas and mandapams.


Ethipothala is a mountain stream cascading down the hills from a height of 21.3 meters into a lagoon. This waterfall is a combination of three streams namely Chandravanka Vagu, Nakkala Vagu & Tummala Vagu.

The dazzling lagoon formed by the falls has a crocodile-breeding centre. After flowing for 3 km, this stream joins with the river Krishna. Ranganadha and Dattatreya temples are found near the waterfalls. People believe that the caves near the waterfalls go to Srisailam.
