The reported move by the Jammu & Kashmir government to tap waters from the Ravi and revive the long-stalled Tulbul Navigation Barrage marks a significant shift in India’s river water strategy following the suspension of the Indus Waters Treaty (IWT). The developments come amid renewed tensions with Pakistan and reflect how geopolitics, federal coordination, and water security intersect in the Himalayan river basin.
What the Indus Waters Treaty Provided
Indus Waters Treaty was signed in 1960 between India and Pakistan, brokered by the World Bank. It is often cited as one of the most durable water-sharing agreements in the world, surviving multiple wars and crises.
Under the treaty:
- India received full rights over the three eastern rivers — Ravi, Beas, and Sutlej.
- Pakistan received rights over the three western rivers — Indus, Jhelum, and Chenab, with limited Indian use permitted for non-consumptive purposes like hydropower.
The treaty imposed technical design and usage constraints on projects on western rivers, including storage and diversion limits. These provisions became points of dispute over several Indian projects.
Why the Treaty’s Suspension Matters
The Centre reportedly put the IWT in abeyance in 2025 following the Pahalgam terror attack. While details of the legal mechanism are complex, the move signals a sharp escalation in India’s approach toward bilateral arrangements with Pakistan.
Suspending the treaty has potential implications:
- Greater operational flexibility for India on western rivers.
- Increased diplomatic tensions with Pakistan.
- Possible international scrutiny given the World Bank’s historical role.
Water treaties are not merely technical agreements but instruments of strategic stability. Any alteration affects regional hydro-politics.
Revival of the Tulbul Navigation Barrage
The Tulbul Navigation Barrage project, initiated in 1984 on the Jhelum near Wular Lake, was halted in 1987 after Pakistan objected under IWT provisions. Islamabad argued that the project would create storage beyond treaty limits.
The J&K government now proposes reviving the project to maintain a minimum water depth in Wular Lake throughout the year. Potential benefits include:
- Year-round navigation in the Kashmir valley.
- Revitalisation of Wular Lake’s ecosystem.
- Support to nearby agriculture and fisheries.
From a governance perspective, this reflects the growing emphasis on inland water transport and ecological restoration.
Ravi Diversion and the Shahpur Kandi Link
The proposal to divert excess Ravi waters from Punjab to the Jammu region highlights inter-state water coordination.
Ravi River is one of the eastern rivers fully allocated to India under the IWT. Historically, some surplus water flowed into Pakistan due to underutilisation on the Indian side.
The completion of the Shahpur Kandi Dam is expected to:
- Enable full utilisation of Ravi waters within India.
- Prevent excess flow across the border.
- Support irrigation in drought-prone districts such as Kathua and Samba.
The plan also includes pumping water from the Chenab near Akhnoor to meet Jammu’s future drinking and irrigation needs, reflecting rising water demand amid urban expansion.
Strategic and Ecological Dimensions
Water in the Indus basin has always carried strategic weight. Any major hydrological intervention has multiple layers:
- Strategic: Enhanced leverage in bilateral relations.
- Economic: Irrigation expansion and agricultural productivity.
- Ecological: Impacts on river flow regimes and wetlands.
- Federal: Coordination between Centre, J&K, and Punjab.
However, large-scale diversions must also consider downstream ecological sustainability and potential legal contestation.
Hydro-Politics in a Changing Climate
Climate change adds a new layer to the Indus basin debate. Glacial melt variability, erratic monsoons, and extreme weather events are altering river flows. In such a context, rigid water-sharing arrangements face stress.
India’s move reflects a broader trend: states are increasingly treating water as both a security and development resource. Yet, unilateral shifts can complicate basin-wide stability.
What to Note for Prelims?
- Indus Waters Treaty (1960) — allocation of eastern and western rivers.
- Eastern rivers: Ravi, Beas, Sutlej (India’s full rights).
- Western rivers: Indus, Jhelum, Chenab (Pakistan’s primary rights).
- Tulbul Navigation Barrage — project on Jhelum near Wular Lake.
- Shahpur Kandi Dam — linked to Ravi water utilisation.
What to Note for Mains?
- Hydro-diplomacy and its role in India–Pakistan relations.
- Strategic implications of suspending long-standing bilateral treaties.
- Balancing regional development with ecological sustainability.
- Federal challenges in inter-state river water management.
- Impact of climate change on transboundary river governance.
