History of Hirakud Dam

The idea for Hirakud Dam was born out of the need to manage the flood-prone Mahanadi River. Floods would often wreak havoc on the fertile plains of Odisha, causing widespread damage to agriculture and human settlements. Sir M. Visvesvaraya, a noted Indian engineer, first suggested constructing a dam to control the floods. The project’s initial plans were drawn up during the colonial period, but it wasn’t until after India’s independence that construction began in earnest.

The foundation stone for the Hirakud Dam was laid by then Prime Minister Pandit Jawaharlal Nehru in 1948, and the dam was inaugurated in 1957. It took nearly a decade to complete, employing thousands of workers and using significant amounts of earth and concrete.
