Dams play a vital role in a country’s water management system, including irrigation, flood control, hydroelectric power generation, and water supply. A clear understanding of the important dams in India, their geographical location, and associated rivers is essential for the UPSC Civil Services Examination.
Important Dams in India
Bhakra Nangal Dam
Located in Himachal Pradesh on the Sutlej River, Bhakra Nangal Dam is one of the highest gravity dams in the world. The dam’s primary purposes include electricity generation and irrigation in Himachal Pradesh, Punjab, Haryana, and Rajasthan.
Constructed across the Mahanadi River in Odisha, Hirakud Dam is one of the world’s longest man-made dams. It is primarily used for irrigation, flood control, and power generation.
Tehri Dam, located on the Bhagirathi River in Uttarakhand, is the highest dam in India. It serves the dual purpose of hydroelectric power production and water supply for irrigation.
Sardar Sarovar Dam
Built on the Narmada River in Gujarat, Sardar Sarovar Dam is a part of the Narmada Valley Project. It provides irrigation facilities to Gujarat and Rajasthan, and electricity generation for four Indian states.
Nagarjuna Sagar Dam
Nagarjuna Sagar Dam, constructed on the Krishna River, lies between Telangana and Andhra Pradesh. The dam provides irrigation water to the Nalgonda, Prakasam, Khammam, and Guntur districts.
Indira Gandhi Canal
