Hirakud Dam, Odisha – The Longest Earthen Dam in the World

Stretching across the Mahanadi River near Sambalpur, Odisha, the Hirakud Dam is the world’s longest earthen dam, with a length of 4.8 kilometers. Built in 1957, it was one of India’s first major multipurpose river valley projects after independence. The dam forms the Hirakud Reservoir, which extends over 55 kilometers and offers stunning panoramic views. It plays a vital role in flood control, irrigation, and hydroelectric power generation for the region. Tourists can visit the Gandhi Minar and Nehru Minar to enjoy breathtaking views of the dam and its vast water body. The site also attracts birdwatchers during winter. Hirakud is not just a dam but a lifeline for Odisha’s agriculture and economy.
