History of Hirakud Dam
Post-Independence Vision
Proposed by Sir M. Visvesvaraya in 1937 to control devastating Mahanadi floods, construction began in 1948. It stands as one of India's first major multipurpose river valley projects after independence.
Historic Inauguration
The dam was officially inaugurated by Prime Minister Jawaharlal Nehru on January 13, 1957, marking a proud moment in India's modern engineering and infrastructure history.
Ongoing Legacy
Over the decades, Hirakud has mitigated floods in the coastal delta region and transformed western Odisha's agricultural landscape through an extensive irrigation network.
Significance
Beyond its primary roles in hydroelectric power generation and flood control, the dam represents the cornerstone of Odisha's agricultural economy. The massive reservoir also serves as a critical wetland habitat, attracting thousands of migratory birds during the winter season.
