Nagarjunasagar Dam was the world’s largest dam to be built of stone and brick during the time of its inauguration. The dam lies very close to the town on Nagarjunasagar in Nalgonda district of Andhra Pradesh. Nagarjunasagar Dam has been constructed over river Krishna. The project work on the dam was started in 1955 and was completed by 1967.
The dam has the capacity to create a water reservoir of 11,472 million cubic meters. It stands at a majestic height of 490 ft and is about 1.6 km long, offering a spectacular view to visitors. It has a total of 26 gates that measure 42 ft wide and 45 ft long.
The dam has a lot of importance in the history of India because it was the first project to be initiated as part of the Green Revolution in the country. It was also the first dam that was used for the purpose of irrigation as well as for providing hydro-electricity to the surrounding region.
Ethipothala Waterfalls are located very close to the Nagarjunasagar town and are some 11 km from the Nagarjunasagar dam. The waterfalls are a result of cascading down of river Chandravanka, a tributary of river Krishna, from a height of 70 ft.
In fact, the waterfalls have the combined waters of three rivers, Chandravanka Vagu, Tummala Vagu and the Nakkala Vagu. The water from the Falls joins river Krishna after it passes through the Nagarjunasagar dam. The fall is about 3 km from the river.
The Falls are a major tourist attraction and are visited by many people throughout the year. The location of the waterfalls is absolutely breathtaking. It is situated amidst a forest, and the cascading waters of the falls provide a picturesque environment.
The government of Andhra Pradesh has built a view point on a hillock that lies close to the Falls. The Ranganatha and Dattatreya temples are very close to the falls.
Nagarjunakonda was an ancient Buddhist island town that is now a part of Andhra Pradesh's Nalgonda district. The town is situated very close to Nagarjunasagar and is about 150 km from the city of Hyderabad. This island town was formed during the 1960s as a result of the submerging of a hill during the construction of the Nagarjunasagar Dam.
The town is famous for being India’s richest Buddhist site and draws travellers from across the country. The hill that submerged in the waters of the lake was known as Sri Parvata during ancient times. The island was named Nagarjunakonda to honour the Buddhist monk Nagarjuna who did a lot to spread the word of Lord Buddha in the region.
It has now been proved that the town used to be a centre of learning during and after the time of Buddha. It had many Buddhist monasteries as well as universities and students from far and near came to study in these institutions.
