The two nuclear-capable neighboring countries are in disagreement regarding the utilization of water from rivers that flow from India into the Indus River basin in Pakistan

- Eastern Rivers: Ravi, Beas, and Sutlej – allocated to India for unrestricted use.
- Western Rivers: Indus, Jhelum, and Chenab – allocated to Pakistan with certain restrictions.
- India is permitted to use the waters of the Western Rivers for non-consumptive purposes such as power generation, navigation, and flood control, subject to specific conditions outlined in the treaty.
- A key feature of the IWT is the establishment of the Permanent Indus Commission, comprising commissioners from both countries. This body serves as a forum for dialogue, dispute resolution, and the exchange of data related to water usage.
- Hydroelectric Projects: India’s construction of hydroelectric projects on the Western Rivers, such as the Kishanganga and Ratle dams, has raised concerns in Pakistan about potential reductions in water flow. Pakistan contends that these projects violate the treaty’s terms.
- Climate Change: Alterations in rainfall patterns and glacial melt due to climate change affect water availability, complicating the management of shared resources.
- Political Tensions: Periodic political tensions between India and Pakistan have sometimes strained cooperation under the treaty.
