Explanation: In Haryana, irrigation canals play a crucial role in supporting agricultural activities. The Bhakra canal, part of the Bhakra Nangal Project, is the most significant in terms of area coverage. This project, one of the largest irrigation and multipurpose projects in India, was initiated in the 1950s and has been instrumental in transforming the agricultural landscape of the region.
The Bhakra canal, along with the Nangal canal, forms the core of the Bhakra Nangal Project. The canal system is designed to provide water for irrigation, drinking, and industrial purposes. It covers a vast area in Punjab, Himachal Pradesh, and Haryana, making it the largest irrigation canal in terms of the area it serves. In Haryana, the canal system has significantly increased the agricultural productivity by providing a reliable source of water for crops, especially in the dry and semi-arid regions of the state.
The Western Yamuna canal, while important, primarily serves the western part of Haryana and is less extensive in coverage compared to the Bhakra canal. It is part of the Upper Yamuna River Basin and is crucial for the agricultural needs of the region but does not cover as much area as the Bhakra canal.
The Jawaharlal Nehru canal, also known as the Indira Gandhi Canal, is another significant canal but is more focused on the states of Punjab and Rajasthan. It serves parts of Haryana but is not as extensive in coverage as the Bhakra canal.
The Gurugaon Canal, while important for local agricultural needs, is a smaller canal that serves a specific region in Haryana. It does not cover as much area as the Bhakra canal, making it less significant in terms of overall coverage.
In summary, the Bhakra canal is the most important irrigation canal in Haryana in terms of area coverage due to its extensive reach and significant contribution to agricultural development in the state.
