Nestled in the heart of Odisha, India, lies a true gem of modern engineering – the Hirakud Dam. This magnificent structure spans across the mighty Mahanadi River, providing vital irrigation and hydroelectric power to the people of the region. But that’s not all that makes this dam so special. With its combination of man-made engineering and natural beauty, the Hirakud Dam is truly a sight to behold. The length of the Hirakud dam is 4.8 kilometres and it has 64 sluice gates and 34 crest gates. Hirakud Dam When it comes to sheer size, the Hirakud Dam is no slouch. In fact, it boasts one of the longest earthen dams in the world, stretching over 4.8 km. But the dam’s engineers didn’t just aim for size – they also aimed for durability and efficiency. By using an innovative method called “roller compacted concrete,” they were able to build a dam that can withstand the test of time and keep the water in check. While the dam’s primary purpose is to provide irrigation water to the parched regions of Odisha, it also generates a significant amount of hydroelectric power. With a capacity of over 260 MW, the dam is a major contributor to the state’s power supply, helping to light up homes and power businesses across the region. But the Hirakud Dam isn’t just about engineering and functionality. It’s also about preserving the beauty and diversity of nature. The reservoir created by the dam covers a massive 630 km² and is home to a variety of plant and animal species, including migratory...

Hirakud dam is the longest earthen dam in the world, built over the Mahanadi river. It is 15 km long and starts from Sambalpur, which belongs to the state of Odisha. Hirakud dam also has a 55-kilometre-long reservoir. In August 2022, it was declared a Ramsar site. It is considered one of the first major multipurpose river valley projects and is the oldest and was started after India’s independence. History of the dam The dam’s foundation stone was laid by Sir Hawthorne Lewis, who was the governor of Odisha at that time. The foundation stone was laid on March 15, 1946. Pandit Jawaharlal Nehru contributed to the dam by laying the first concrete batch after two years on April 12, 1948. The government appointed the Committee of Mazumdar to keep an eye on the project. The cost of the project was Rs 92.80 crore. It was estimated to be completed by June 1955. For the dam, 1,347,000 acres were selected for irrigation, and for electricity power, 48,000 kW were generated. The foundation stone for the dam was laid in 1946, but the dam was completed in 1953 and was formally inaugurated by the then Prime Minister, Jawaharlal Nehru. Then Prime Minister Jawaharlal Nehru inaugurated the dam on January 13, 1957. The final cost of making the longest dam was Rs 1,000.2 million. The power with agricultural irrigation was generated in 1956, but with full potential, the power and agricultural irrigation started in 1966.

Chief Engineer, Upper Mahanadi Basin Ananda Chandra Sahu said at the time of opening of the gates, water level in Hirakud Dam Reservoir was 613.71 ft. It will take 36 hours for the released water to reach Mundali. "There is no possibility of flooding on the downstream. As per the current inflow, we will keep the five gates open," he said. While the upstream of the dam received 19.69 mm rainfall in the last 24 hours, the downstream recorded 17.85 mm rain during the period. Official sources said the water level of Hirakud Dam stood at 613.27 ft against the full reservoir level of 630 ft at 6 pm on Monday. Similarly, the inflow of water into the reservoir was 1,08,515 cusec and outflow was 1,16,541 cusec including 75,660 cusec released through the spillway, 36,495 cusec to power channel, 4,113 cusec for irrigation and 273 cusec for industries at 6 pm on the day. Last year, the authorities had released the first floodwater from the dam on July 11.There are 98 gates to release floodwater from Hirakud Dam. While 64 are sluice gates, the rest 34 are crest gates. Each sluice gate has the capacity to discharge 16,440 cusec of water when the reservoir level is at 630 ft, which is also termed as the danger level. Similarly, each crest gate has the potential to discharge 16,238 cusec of water at 630 ft. SAMBALPUR: The authorities of Hirakud Dam released the season's first floodwater from five gates on Monday. The floodwater was released from three gates on the left and two on the righ...
