Basha Dam is to be constructed on ___________?

  • River Sutlaj
  • River Jhelum
  • River Chenab
  • None (On Indus River in Gilgit-Baltistan)
Correct Answer: D. None (On Indus River in Gilgit-Baltistan)

Detailed Explanation

Basha Dam, officially called Diamer-Bhasha Dam, is a large-scale multipurpose dam project under construction in Gilgit-Baltistan, Pakistan. This dam is being built on the Indus River, one of the largest rivers in Asia. The project site is located between Khyber Pakhtunkhwa (Kohistan District) and Gilgit-Baltistan (Diamer District), hence the name "Diamer-Bhasha."The main purpose of constructing Basha Dam is to address Pakistan’s growing need for water storage, irrigation support, and hydroelectric power generation. Once completed, the dam will help:




  • Store up to 8.1 million acre-feet (MAF) of water, reducing water shortages.




  • Generate approximately 4,500 megawatts of hydroelectric power, contributing to the national grid.




  • Control floods by regulating water flow downstream of the Indus River.




  • Extend the life of downstream reservoirs such as Tarbela Dam by trapping sediments upstream.The other rivers mentioned in the options are incorrect:






  • River Sutlaj: Houses major dams like Bhakra and other projects in India, not Basha.




  • River Jhelum: Known for Mangla Dam, but not Basha Dam.




  • River Chenab: Includes Marala and other barrages but not this project.




Basha Dam is strategically important for Pakistan’s water security and renewable energy goals. The Indus River was chosen due to its high water flow and favorable topography for a large reservoir. The project is also significant in the context of climate change, as it will improve water management in a country heavily reliant on river-fed agriculture.


Thus, the correct answer is: None of these – the dam is being built on the Indus River in Gilgit-Baltistan.
