The mighty Indus River, often referred to as the lifeline of Pakistan, is one of the longest rivers in the world, flowing through China, India, and Pakistan. Its extensive network of tributaries significantly contributes to its grandeur and importance in the region.
Jhelum River
The Jhelum River, originating from the Indian-administered territory of Jammu and Kashmir, is one of the primary tributaries of the Indus. With a length of approximately 725 kilometers, it meanders through the Indian-administered region and enters Pakistan near the city of Jhelum. The Jhelum contributes significantly to the Indus’s water volume, providing essential water for irrigation and hydropower generation.
Chenab River
The Chenab River, the largest tributary of the Indus, originates from the Indian state of Himachal Pradesh and flows through the Indian-administered union territory of Jammu and Kashmir before entering Pakistan. Its course within Pakistan covers a substantial part of the country, making it a vital contributor to the Indus’s water resources. The Chenab plays a crucial role in agriculture, supporting the fertile plains of Punjab, and its waters are harnessed for hydropower generation through dams such as the Tarbela Dam.
Ravi River
Originating in the Indian state of Himachal Pradesh, the Ravi River flows through the Indian-administered union territory of Jammu and Kashmir before entering the Chamba district of Himachal Pradesh and ultimately reaching Pakistan. Though it is one of the smaller tributaries, the Ravi is essential for the region’s irrigation and contributes to the overall flow of the Indus.
Sutlej River
The Sutlej River, originating from Tibet, China, enters India and flows through the Indian states of Himachal Pradesh and Punjab before reaching Pakistan. It is the easternmost tributary of the Indus and covers a vast distance through the Indian subcontinent. The Sutlej’s waters are crucial for agriculture, providing irrigation to the fields of Punjab, and it is also a significant source of hydropower through dams like the Bhakra Dam.
Beas River
The Beas River, a tributary of the Sutlej, has its origins in the Indian state of Himachal Pradesh. It flows through the Kullu Valley before entering the Indian state of Punjab and finally reaching Pakistan. Though smaller in size compared to some other tributaries, the Beas contributes to the overall water resources of the Indus River system, supporting agriculture and local ecosystems.
