The Indira Gandhi canal (originally :Rajasthan canal) is the longest canal of india. It starts from the Harike Barrage at Harike, a few kilometers below the confluence of the Satlej and Beas rivers in the indian state of Punjab and terminates in irrigation facilities in the Thar Desert in the north west of Rajasthan state.

Origin of Indira Gandhi Canal

The Indira Gandhi Canal, also known as the Rajasthan Canal, is one of the largest irrigation canals in India. It originates from the Harike Barrage in Punjab and extends through the states of Punjab, Haryana, and Rajasthan. Let's explore the details of its origin and significance.

1. Harike Barrage:
The Indira Gandhi Canal originates from the Harike Barrage, which is located at the confluence of the Beas and Sutlej rivers in Punjab. The barrage serves as a head regulator for the canal, controlling the flow of water into it.

2. Purpose and Significance:
The primary purpose of the Indira Gandhi Canal is to provide irrigation water for the arid regions of Rajasthan. It helps in transforming the barren lands of the Thar Desert into fertile agricultural fields. The canal also supports drinking water supply, livestock, and industrial needs in the region.

3. Length and Route:
The total length of the Indira Gandhi Canal is approximately 649 kilometers. It traverses through Punjab, Haryana, and Rajasthan, covering numerous districts and providing water to thousands of hectares of farmland.

4. Canal Structure:
The canal is a gravity-flow canal, which means it relies on the natural slope of the land to carry water from the source to the destination. It is a lined canal, which reduces water seepage and ensures efficient water supply. The canal has a capacity of carrying around 18,000 cubic feet per second of water.

5. Construction and Commissioning:
The construction of the Indira Gandhi Canal began in 1958, and it was completed in 1987. It was a massive engineering feat, involving the excavation of vast stretches of land, construction of numerous distributaries, and the establishment of water management infrastructure.

6. Benefits and Impact:
The Indira Gandhi Canal has had a transformative impact on the agricultural landscape of Rajasthan. It has facilitated the cultivation of various crops, including wheat, mustard, cotton, and vegetables. The canal has also contributed to increased agricultural productivity, improved living standards, and socio-economic development in the region.

In conclusion, the Indira Gandhi Canal originates from the Harike Barrage in Punjab. It is an essential irrigation canal that plays a crucial role in transforming the arid regions of Rajasthan. The canal's construction and commissioning have brought about significant benefits and positively impacted the lives of people in the region.
