What Happened
- The central government stated that Pakistan will not receive "a single drop" of water from Indian-controlled rivers in the coming years, signalling a hardening of India's position following the suspension of the Indus Waters Treaty (IWT) in April 2025.
- India suspended the IWT in April 2025 citing national security concerns following the Pahalgam terrorist attack in Kashmir; the suspension has remained in place despite a U.S.-negotiated ceasefire in May 2025.
- India is accelerating multiple infrastructure projects that will increase its utilisation of waters from the western rivers (Indus, Jhelum, Chenab) — rivers which, under the original treaty, were allocated predominantly to Pakistan.
- Key projects being pursued include the Dulhasti Stage-II Hydropower Project on the Chenab River (approved January 2026), the Chenab-Beas Link Tunnel in Himachal Pradesh, and reservoir flushing operations at Salal and Baglihar dams.
- India also conducted off-season stoppage of water flow on the Chenab River from the Baglihar Dam as a short-term punitive action following the suspension, without providing advance notice to Pakistan.

The Indus Waters Treaty — Structure, History, and Provisions
The Indus Waters Treaty was signed on September 19, 1960, in Karachi, between India and Pakistan, with the World Bank as guarantor and mediator. It remains one of the world's most enduring bilateral water-sharing agreements, having survived three wars between the two countries.
- The treaty divided the six rivers of the Indus basin between the two nations: the three eastern rivers (Ravi, Beas, Sutlej) were allocated to India; the three western rivers (Indus, Jhelum, Chenab) were allocated predominantly to Pakistan.
- India received approximately 20% of the total water flow (33 million acre-feet/year from the eastern rivers); Pakistan received approximately 80% (135 million acre-feet/year from the western rivers).
- India retains non-consumptive use rights on the western rivers — it may generate hydropower and draw limited irrigation water, but must not significantly alter flow.
- The treaty established a Permanent Indus Commission (PIC), with one commissioner from each country, to meet at least once a year and resolve disputes through dialogue.
- Disputes that cannot be resolved by the PIC can be escalated to a Neutral Expert (for technical questions) or a Court of Arbitration (for legal interpretation disputes), both under World Bank processes.
Connection to this news: India's suspension of the IWT means the PIC meetings are frozen, the dispute resolution mechanism is non-functional, and India is proceeding with projects on the western rivers that would ordinarily require prior notice and consultation under the treaty framework.
Chenab-Beas Link Tunnel and India's Infrastructure Strategy
The proposed Chenab-Beas Link Tunnel aims to divert surplus water from the Chandra River (a tributary of the Chenab) in Lahaul-Spiti, Himachal Pradesh, through an 8.7-kilometre underground tunnel beneath the Pir Panjal range into the Beas River basin for use within India.
- The Chenab is a western river under the IWT — fully utilising its waters was impermissible under the treaty's consumptive-use restrictions on western rivers.
- The suspension of the IWT removes the treaty constraint, allowing India to aggressively develop storage and diversion infrastructure on Chenab tributaries.
- Baglihar Dam on the Chenab (commissioned 2008) was itself a subject of IWT dispute; Pakistan challenged its design at the World Bank Neutral Expert level (2005–2007), receiving a partial ruling.
- Salal Dam (on the Chenab, Jammu and Kashmir) is India's oldest hydropower project on a western river; reservoir flushing to clear silt improves storage capacity but temporarily pulses high sediment loads downstream into Pakistani territory.
- The Dulhasti Stage-II Hydropower Project, approved in January 2026, represents India's first major new western-river approval after the treaty suspension.
Connection to this news: These projects collectively shift the long-term hydrological calculus — building storage and diversion capacity that will reduce seasonal flows into Pakistan even if the IWT is eventually restored, giving India lasting geopolitical leverage.
Water as a Strategic Resource — Hydro-Politics in South Asia
Water scarcity is emerging as one of the most consequential geopolitical fault lines in South Asia. Pakistan is classified as water-stressed, with per-capita water availability well below global thresholds; its agriculture, which employs over 40% of the workforce, is almost entirely dependent on Indus basin irrigation.
- Pakistan's Indus Basin Irrigation System (IBIS) is the world's largest contiguous irrigated area, covering roughly 16 million hectares.
- The three western rivers — Indus, Jhelum, Chenab — account for approximately 80% of all water flowing into Pakistani agriculture.
- Climate change projections (IPCC) indicate Himalayan glaciers feeding the Indus basin are receding, making future water availability increasingly uncertain even without political disruption.
- The UN Convention on the Law of the Non-Navigational Uses of International Watercourses (1997), which India has not ratified, establishes principles of equitable utilisation and no significant harm to co-riparian states.
Connection to this news: India's declaration that Pakistan will receive "not a single drop" from Indian-held rivers goes beyond treaty suspension to signalling a strategic intent to use water as a coercive instrument — raising serious questions under international water law and humanitarian principles that UPSC Mains frequently tests.
UPSC Angle: India-Pakistan Relations and the Role of International Law
The suspension of the IWT and India's accelerated water projects intersect with several UPSC-relevant international legal principles: sovereign rights over natural resources, the doctrine of equitable utilisation, the obligation not to cause transboundary harm, and the role of international institutions (World Bank, ICJ, Permanent Court of Arbitration) in resolving bilateral disputes.
- Pakistan has filed cases at the Permanent Court of Arbitration (PCA) and the World Bank over IWT disputes — India contests the PCA's jurisdiction, asserting the treaty's dispute resolution mechanism must be followed in sequence.
- In 2016, Pakistan filed a request for a neutral expert and separately for the PCA Court of Arbitration over the Kishanganga and Ratle hydropower projects on western-river tributaries.
- India's position is that the suspension is consistent with international law as a "countermeasure" in response to Pakistan's continued support for cross-border terrorism.
- Pakistan argues the treaty has no exit clause and no provision for unilateral suspension.
Connection to this news: The article's framing — "not a single drop" — signals that India views the IWT suspension not as a temporary measure but as a permanent policy shift, fundamentally altering the treaty's 65-year architecture and setting a precedent for using transboundary water as a strategic tool.
