The Bhakra Nangal Dam is actually a system of two separate structures. Together, they harness the mighty Sutlej River. They provide life-giving water and electricity to a vast region of North India. Understanding this project is to understand India’s post-independence journey. It is a story of vision, sacrifice, and incredible achievement.
What is the Bhakra Nangal Dam? A Tale of Two Dams
Many people use the term “Bhakra Nangal Dam” as if it were a single entity. However, it is a complex of two main dams located about 10 kilometers apart. Both are crucial components of the larger Bhakra-Nangal Project.
The Bhakra Dam: A Concrete Gravity Giant
The Bhakra Dam is the primary structure. It is a massive concrete gravity dam built across the Sutlej River. It is located in a gorge near the now-submerged village of Bhakra in Himachal Pradesh. Its sheer size is awe-inspiring. It is one of the highest gravity dams in the world.
- Type: Concrete Gravity Dam. This means it relies on its own weight to resist the immense pressure of the water it holds back.
- Purpose: Its main functions are to store water for irrigation, generate hydroelectricity, and control floods.
- Reservoir: The Bhakra Dam creates the vast Gobind Sagar Lake, a massive man-made reservoir.
The Nangal Dam: A Supporting Barrage
Downstream from the Bhakra Dam lies the Nangal Dam. It is located in the town of Nangal in Punjab. The Nangal Dam is a barrage, which is a much smaller type of dam. Its primary role is not water storage but water regulation.
- Type: Barrage or Diversion Dam.
- Purpose: It diverts the water released from the Bhakra Dam into the Nangal Hydel Channel. This channel feeds a series of power plants and the vast network of irrigation canals. It also acts as a balancing reservoir to ensure a steady water supply.
So, while Bhakra is the giant that stores the water, Nangal is the crucial regulator that distributes it. Together, they form the heart of the project.
