Introduction
Hirakud Dam, located near Sambalpur in Odisha, is one of India's most remarkable engineering achievements. Built across the mighty Mahanadi River, it is renowned as the world's longest earthen dam. The project was undertaken to control devastating floods, provide irrigation, and generate hydroelectric power for the region.
Today, Hirakud Dam stands as a symbol of Odisha's progress and continues to play a vital role in the state's economy and agriculture.
The Need for Hirakud Dam
Before the construction of the dam, the Mahanadi River frequently caused severe flooding in Odisha. The catastrophic flood of 1937 highlighted the urgent need for a permanent flood-control solution.
The floods repeatedly damaged crops, villages, and infrastructure, affecting thousands of people. This led planners and engineers to propose a large dam project on the Mahanadi River.
Historical Background
Early Planning
The idea of constructing a dam across the Mahanadi River was first seriously considered during British rule. However, the project gained momentum after India's independence.
Dr. B. R. Ambedkar, who played a significant role in India's water resource planning, strongly supported multipurpose river valley projects, including Hirakud.
Foundation Stone
The foundation stone of Hirakud Dam was laid on 12 April 1948 by Pandit Jawaharlal Nehru, India's first Prime Minister.
The project became one of the first major multipurpose river valley projects undertaken after independence.
