Explanation: The Bhakra Nangal Dam is a significant multi-purpose hydroelectric and irrigation project located on the Satluj River in Himachal Pradesh, India. It is one of the largest and most important dams in India, contributing significantly to the region's water and power needs. The dam is part of a larger project that includes the Nangal Dam, which is located downstream on the Sutlej River.
The Satluj River, also known as the Sutlej, is one of the five major rivers of the Punjab region. It originates from the Mansarovar Lake in Tibet and flows through Himachal Pradesh before joining the Indus River in Pakistan. The Bhakra Nangal Dam was constructed to harness the river's water for irrigation, power generation, and flood control.
The construction of the Bhakra Nangal Dam began in 1948 and was completed in 1963. It is a concrete gravity dam with a height of 226 meters, making it one of the tallest dams in the world. The dam has a reservoir capacity of about 9.34 billion cubic meters and generates approximately 1,325 MW of electricity. The project has significantly improved the agricultural productivity of the region by providing irrigation water to over 1.4 million hectares of land in Punjab, Haryana, and Rajasthan.
The Bhakra Nangal Dam is not only a significant engineering feat but also a symbol of India's post-independence development efforts. It has played a crucial role in the economic development of the region by providing reliable water and power resources. The dam's construction and operation have also faced various environmental and social challenges, including the displacement of local communities and the impact on the river's ecosystem.
In summary, the Bhakra Nangal Dam is the correct answer as it is the major dam situated on the Satluj River in Himachal Pradesh. It is a critical infrastructure project that has had a profound impact on the region's water and power supply, as well as its agricultural productivity. Understanding the significance of the Bhakra Nangal Dam is essential for comprehending the geography and development of Himachal Pradesh and the broader Punjab region.
