So, Pair 1 is correct.
World’s largest masonry dam protected with 26 gates measuring 124.663m in height, Nagarjunasagar Dam is located in the Nalgonda District of Telangana. It is built across the river Krishna and not the river Tungabhadra. The dam has a storage capacity of nearly 11,472 million cubic meters with an irrigation capacity for 9.81 lac acres of land. The dam measures150m tall and 16 km in length while also being a major tourist attraction. In fact, it is among the first irrigation projects started by the Indian Government as an element of the Green Revolution. So, Pair 2 is not correct.
Reaching a staggering height of 260 meters, the imposing Tehri Dam is one of the tallest dams in the world and the tallest dam in India, built on the Bhagirati river, which merges with the Alaknanda river to form River Ganga at Devprayag. An engineering marvel in itself, Tehri Dam not only provides more than 1,000 MW of hydroelectricity but also is a popular tourist attraction in Uttarakhand. The dam reservoir, also known as Tehri Lake, is usually flocked with tourists interested in boating and is slowly becoming a prominent hub for adventure tourism in Uttarakhand. So, Pair 3 is correct.
Hirakud Dam is one of the longest dams in the world, located at a distance of 15km from the main city of Sambalpur in Odisha. It is the world’s longest earthen Dam, about 16 miles and around 26 km in length. Built on the River Mahanadi (not Tapi river) at the cost of Rs.1000 million, the Hirakud Dam project is one of its kind in the entire country. After India’s independence, it is said to be one of the first major multi-use river valley projects. From horizon to horizon, the reservoir forms the largest artificial lake in Asia, with an area of 746 sq.Kms. and shoreline over 640 kms. A 21 Kilometres drive on the dyke offers a unique experience of calm serenity and majesty of nature. So, Pair 4 is not correct.
