Hirakud Dam: Asia’s Longest Earthen Dam

The Colossus of the Mahanadi

Imagine a body of water so vast it stretches from horizon to horizon, a shimmering expanse that forms the largest artificial lake in Asia – this is the Hirakud Reservoir. Holding it in its monumental embrace is the Hirakud Dam, a colossus of earth and concrete standing in “lonely majesty” across the mighty Mahanadi River near Sambalpur, Odisha. 

More than just an engineering marvel, Hirakud is a living monument to a newly independent India’s ambition and vision. It is a structure of profound paradoxes—a symbol of progress that holds within its depths a history of submerged temples and forgotten legends. It is a powerhouse of development that doubles as a vital ecological sanctuary, earning the prestigious designation of a Ramsar site for its biodiversity.   

This dam is a destination with a story to tell, a place where modern ingenuity meets ancient mystique. This guide is your definitive companion for exploring every facet of the Hirakud Dam in 2026. It will take you beyond the statistics and into the heart of its history, its purpose, and its vibrant life as one of Odisha’s premier tourism destinations.

A Legacy Forged in Earth and Water: The Story of Hirakud Dam

The story of Hirakud is not one, but three powerful narratives woven together by the waters of the Mahanadi: a tale of national ambition, a legend of ancient riches, and a poignant account of loss and remembrance.

From a Post-Independence Dream to a Concrete Reality

In the early 20th century, the Mahanadi River was a force of both life and destruction, its devastating floods regularly ravaging the delta region. The vision to tame its waters was first proposed by the eminent engineer Sir M. Visveswararya. After the catastrophic floods of 1937, this vision gained unstoppable momentum.   

Following India’s independence, the project became a cornerstone of the nation’s development. In 1945, a committee chaired by Dr. B. R. Ambedkar, the then Member for Labour, made the pivotal decision to invest in this multipurpose project. On March 15, 1946, Sir Hawthorne Lewis, the Governor of Odisha, laid the foundation stone, marking the beginning of an epic undertaking.   

The scale of the project was immense for its time. Prime Minister Jawaharlal Nehru himself laid the first batch of concrete on April 12, 1948. The dam was completed in 1953 and formally inaugurated by Nehru on January 13, 1957, at a total cost of ₹100.02 crores—a monumental sum in that era. It stood as one of India’s first and most ambitious river valley projects, a symbol of a new era.   

The Land of Diamonds Beneath the Waves

Long before concrete was poured, the land beneath Hirakud held a different kind of treasure. The name ‘Hirakud‘ itself is a direct clue, translating to “Diamond Island“. Ancient texts from chroniclers like Ptolemy and Gibbon referred to this region around Sambalpur as a famed source of the world’s finest diamonds, coveted even by the Romans.   

These were not diamonds from deep mines, but alluvial gems washed down from the Vindhya mountains and deposited in the riverbed by the Mahanadi and its tributaries. The unique geography of Hirakud island, which split the river into two channels, created a natural sieve where diamonds, gold dust, and other semi-precious stones would settle.   

For centuries, the local Jhara community practiced the art of finding these treasures. As described by British officer Major Ouseley in 1840, thousands of villagers would build a temporary embankment each March, divert the river’s flow, and pan the stagnant pools for diamonds and gold. The diamonds went to the Raja of Sambalpur, while the gold provided a livelihood for the community. This ancient story adds a layer of incredible mystique to the dam that now stands on that very spot.   

Echoes from the Deep: The Submerged Temples and Displaced Lives

The creation of this national symbol came at a significant human cost. The vast reservoir, essential for the dam’s function, submerged an enormous area, displacing an estimated 1.5 lakh people from 26,561 families across 369 villages. The lives and histories of these communities were forever altered, a poignant counter-narrative to the story of progress.   

Beneath the serene waters also lie the ghosts of over 200 temples, their spires and structures now part of an underwater world. During the peak summer months of May and June, as the water level recedes, these “lost temples” dramatically resurface. This haunting spectacle has become a major attraction for historians, photographers, and even scuba diving enthusiasts seeking to explore this submerged heritage.   

This duality—the creation of a modern marvel and the inundation of an ancient landscape—is the emotional core of Hirakud’s story. It reminds every visitor that the serene lake holds not just water, but also memories, legends, and the echoes of a life that once was.

Hirakud Dam by the Numbers: An Engineering Marvel Unpacked

The sheer scale of Hirakud is difficult to comprehend until you see it. The statistics behind its construction are as staggering as the view from its crest. The materials used—earth, concrete, and masonry—were enough to build a paved road 8 meters wide from Kanyakumari to Kashmir. 

The main dam, a composite structure of earth and concrete, stretches for an impressive 4.8 km between two hills, Laxmidungri on the left and Chandili Dunguri on the right. This is flanked by 21 km of earthen dykes, bringing the total length of the structure to a world-record 25.8 km. It stands at a maximum height of 60.96 meters (about 200 feet), holding back a reservoir that spreads over 743 sq. km.   

A key feature of the dam’s design is its two massive spillways, equipped with a complex system of gates to manage the river’s flow. Contrary to some popular belief, the dam has a total of 98 gates, a testament to its intricate design.

More Than Just a Wall: The Dam’s Multipurpose Mission

Hirakud was designed as a multipurpose project, and its benefits continue to shape the economy and safety of Odisha. Its primary functions are:

• Flood Control: It provides critical flood protection to 9,500 sq. km of the Mahanadi delta, safeguarding countless lives and vast areas of agricultural land in districts like Cuttack and Puri.   
• Irrigation: The dam is the lifeline for agriculture in the region, irrigating over 2,640 sq. km of land for both Kharif (monsoon) and Rabi (winter) crops across Sambalpur, Bargarh, Bolangir, and Subarnpur districts.   
• Power Generation: With a total installed capacity of 307.5 MW, its two powerhouses at Burla and Chiplima are significant contributors to the state’s energy grid.   

However, this 67-year-old marvel is not a static relic. It is a dynamic system that requires constant upkeep. Over the decades, siltation has reduced its water-holding capacity by nearly 24%. To address this and prepare for future climate eventualities, plans are underway for a major overhaul, including the construction of an additional spillway to handle increased flood discharge capacities, ensuring the dam remains a steadfast guardian for generations to come.

• Sarsatia : a traditional sweet native to Sambalpur in Western Odisha, made using the resin of the Ganjer (or Ganjari) tree, combined with rice flour and sugar to create a subtly sweet, crispy treat with an earthy aroma.

 

• Pakhala Bhat: The soul food of Odisha, this is a dish of fermented rice served with accompaniments like fried fish, roasted vegetables, and yogurt. It is incredibly refreshing, especially in the summer.   
• Dalma: A uniquely Odia dish, this is a nutritious stew made from lentils and a medley of vegetables, tempered with a special five-spice mix called panch phoron.   

  Panasa Tarkari: A delectable curry made from unripe jackfruit, cooked with potatoes and onions in a blend of local spices.   
• Aamisa Jhol: This term covers a range of non-vegetarian curries. Look for Kukra Jhol (chicken curry) or Jhuri Bhaja (a special fish curry), which are local favorites.   
• Sweets: End your meal with famous Odia sweets like Chenna Poda (a baked cheese dessert) and Rasabali (deep-fried cheese patties soaked in thickened milk).   

For an authentic taste, visit restaurants in Sambalpur like Kedia’s Restaurant, Spicy Affairs, or The Punjab Grill, which are well-regarded by locals and visitors alike.   

Beyond the Dam: Exploring the Jewels of Sambalpur

Hirakud Dam is the perfect gateway to exploring the rich cultural, spiritual, and natural treasures of the Sambalpur region. Each of the nearby attractions tells a story deeply connected to the Mahanadi River and the land it nourishes.

Debrigarh Wildlife Sanctuary: Where Nature Roams Free

 

Nestled along the vast Hirakud reservoir, Debrigarh Wildlife Sanctuary offers a unique ecosystem where forest life meets an aquatic habitat. This sanctuary is a crucial corridor for wildlife and is home to a healthy population of Indian Bison (Gaur), leopards, sambar deer, and the elusive chousingha (four-horned antelope). It is also a birdwatcher’s paradise, with over 234 species recorded.   

Visitors can explore the sanctuary through guided jungle safaris, which typically last 2.5 hours. It is mandatory to book an entire vehicle, with prices ranging from ₹2,100 for a 4-seater to ₹4,725 for a 12-seater AC vehicle. The sanctuary is generally open from 6:00 AM to 4:00 PM, with an entry fee of ₹40 for Indian nationals.   

Maa Samaleswari Temple: The Spiritual Heart of Sambalpur

The Maa Samaleswari Temple is the spiritual epicenter of Western Odisha. This revered 16th-century shrine is dedicated to the goddess Samaleswari, the region’s presiding deity, who is believed to be an incarnation of Durga. The temple architecture is a fine example of the Kalinga style.   

A major attraction for visitors is the spectacular evening Light and Sound Show. This 37-minute presentation uses stunning visuals and a compelling narrative to bring the glorious history of the temple and the Sambalpur region to life. The temple is open for darshan from early morning (around 5:00 AM) to night (around 9:00 PM), with the show typically starting at 7:00 PM.   

The Leaning Temple of Huma: India’s Own Pisa with a Fishy Tale

Prepare to be amazed at the Leaning Temple of Huma, one of the only leaning temples in the world. Located on the banks of the Mahanadi, this temple dedicated to Lord Shiva defies architectural logic. The main temple structure leans significantly in one direction, while the smaller shrines and even the boundary walls within the complex tilt in other directions—a mystery that has puzzled engineers and historians for centuries.   

Adding to the temple’s charm is the legend of the ‘Kudo’ fish. These large, reddish-colored fish swim in the river by the temple ghats and are considered sacred. They are so tame that they will eat food directly from the hands of devotees. Local folklore holds that anyone who harms or catches these fish is cursed to turn to stone.   

Ghanteswari Temple: The Lighthouse of a Thousand Bells

The Ghanteswari Temple offers a truly unique sensory experience. As its name suggests, the temple is adorned with thousands upon thousands of bells (ghanti) of all sizes, hung by devotees whose wishes have been fulfilled. The constant, gentle chiming of these bells creates an atmosphere of profound peace and devotion.   

Before the Hirakud Dam was built, this spot on the Mahanadi was known for its treacherous whirlpools. The temple served as a “lighthouse without light.” Early sailors would listen for the sound of the temple’s large bells, carried by the strong winds, which warned them of the approaching danger. The dam’s construction tamed the river’s flow, making the waters safer and transforming the temple’s role from a vital navigational aid to a beloved spiritual destination.   

Hirakud Eco Retreat: Glamping by the Great Reservoir

For a touch of luxury amidst nature, the Hirakud Eco Retreat is an unparalleled experience. This seasonal “glamping” event, organized by Odisha Tourism, sets up luxurious Swiss tents with five-star amenities right on the banks of the reservoir. The retreat typically runs from mid-November to mid-February.   

Packages include accommodation in premium air-conditioned tents, all meals, curated cultural performances in the evenings, and access to a host of activities like water sports, ATV rides, and guided tours to nearby attractions. It offers a perfect blend of comfort, adventure, and cultural immersion, making it a highly sought-after experience.
