Sharp Drop in Chenab Flows Sparks Alarming Indus Water Treaty Concerns
Sharp drop in Chenab flows has raised serious Indus Water Treaty concerns as Pakistan warns of threats to Kharif crops, irrigation supplies, food security, and regional water stability amid rising tensions over upstream regulation
ISLAMABAD/LAHORE: Sharp drop in Chenab flows has intensified concerns in Pakistan over possible violations of the Indus Water Treaty (IWT), threatening irrigation supplies during the crucial Kharif sowing season and raising fears of severe agricultural losses.
According to official accounts, water flows in the Chenab River at Marala Headworks sharply declined on May 2, 2026, dropping to 9,037 cusecs from approximately 20,930 cusecs. Authorities suspect that upstream regulation by India, including the filling of the Baglihar Dam reservoir, may have caused the sudden reduction.
Sharp Drop in Chenab Flows Raises Alarm
The sudden reduction of nearly 11,893 cusecs in Chenab River flows has sparked immediate concerns among Pakistani authorities and agricultural stakeholders. Officials noted that the river experienced sharp fluctuations throughout the day, creating uncertainty over water availability downstream.
Pakistan’s Indus Waters Commissioner, Syed Mehr Ali Shah, confirmed that the reduced flows appeared linked to upstream regulation activities in Indian Illegally Occupied Jammu and Kashmir.
“Yes, there is a dip. In the absence of rainfall in the catchment, this event is due to regulation of upstream works. The reduction cannot justify treaty requirements and is therefore a violation,” he stated.
He further said Pakistan had formally requested explanations from Indian authorities regarding the significant variations observed at Marala Headworks.
Kharif Crops Under Serious Threat
The sharp drop in Chenab flows comes at a critical period when Punjab farmers are actively preparing for the Kharif season. The Chenab River plays a major role in irrigating agricultural lands across central and southern Punjab.
Farmers are currently:
- Preparing cotton fields
- Raising rice nurseries
- Irrigating orchards and vegetables
- Managing sugarcane cultivation
Officials fear that continued disruptions could severely affect agricultural productivity, reduce crop yields, and worsen food security challenges in Pakistan.
A Punjab Irrigation Department official warned that Pakistan lacks sufficient storage infrastructure on the Chenab River, making the country highly vulnerable to sudden upstream water regulation.
Indus Water Treaty Concerns Intensify
The latest development has renewed debate over the future of the Indus Water Treaty, brokered by the World Bank in 1960 between Pakistan and India.
In April 2024, India announced it was placing the treaty in abeyance, a move Pakistan strongly rejected as illegal under international law. Later, the Court of Arbitration clarified that the treaty remains legally binding and cannot be unilaterally suspended.
Experts believe the current fluctuations in Chenab flows could violate provisions of Annexure D of the treaty, which regulates operational procedures for upstream hydropower projects.
Former Indus Waters Commissioner Jamaat Ali Shah stressed that treaty inspection mechanisms must be activated immediately to determine whether the reduction resulted from operational adjustments or deliberate water storage.
Officials Call for Urgent International Attention
Several Pakistani officials and water experts have urged the government to raise the issue at international forums.
Seasoned politician Mohsin Leghari said:
“Pakistan must take the issue of low Chenab flows seriously. Any reduction in river water will directly affect growers and agricultural productivity.”
Former commission official Sheraz Jamil Memon also described the suspension of treaty mechanisms as unfortunate and called for on-site inspections of Indian hydropower projects.
Officials warned that repeated fluctuations in river flows could destabilize regional cooperation and further strain bilateral relations.
Historical Flow Data Shows Abnormal Reduction
Historical records indicate that Chenab River flows at Marala during early May typically range between 30,000 and 35,000 cusecs.
However, this year’s average dropped to approximately 14,214 cusecs — a massive deviation from normal seasonal patterns.
Official data revealed:
- Flows dropped from 20,930 cusecs to 9,037 cusecs within hours
- Chenab contributed only 11.4% to total system inflows
- Indus River contributed 33.2% during the same period
Authorities also recalled similar incidents in December 2025 and May 2025, when Chenab flows reportedly fell dramatically after reservoir filling activities at Baglihar, Salal, and Pakal Dul projects.
Pakistan’s Water Security Challenges Deepen
Pakistan already ranks among the world’s most water-stressed countries. Climate change, glacier melt, population growth, and outdated irrigation infrastructure have intensified pressure on the country’s fragile water resources.
The latest Chenab River episode highlights broader concerns regarding:
- Water security
- Food security
- Agricultural sustainability
- Climate vulnerability
- Regional stability
Experts warn that unpredictable river flows can damage Pakistan’s economy, particularly agriculture, which contributes significantly to employment and GDP.
According to the World Bank, Pakistan faces increasing climate-related water risks that require urgent regional cooperation and long-term adaptation planning.
Need for International Monitoring and Cooperation
Water experts argue that international institutions including the World Bank and the United Nations should play a more active role in ensuring compliance with treaty obligations.
Environmental experts believe continued uncertainty over river flows could increase tensions in South Asia, where millions depend on transboundary river systems for survival.
Observers say effective diplomacy, transparent data-sharing, and cooperative water management remain essential for preventing future disputes.
Conclusion
The sharp drop in Chenab flows has become a serious test for the Indus Water Treaty and regional water diplomacy. At a time when Pakistan faces mounting climate challenges and growing agricultural demands, sudden disruptions in river flows could have devastating economic and humanitarian consequences.
With Kharif crops already under pressure, Pakistan is expected to intensify diplomatic and legal efforts to safeguard its water rights under international law. Experts warn that long-term peace and food security in the region depend on respecting treaty obligations and maintaining cooperative water governance.
