Reassessment of the Water Dispute in the Indus Basin: Data Analysis Versus Crisis Claims

The article's author disputes Pakistan's claims of an impending water crisis in the Indus basin, arguing that reality points to abundant water inflows and highlights structural issues in water resource management rather than scarcity.

Analysis of Hydrological Data for 2025

Recent Pakistani assertions regarding an approaching water crisis in the Indus basin and attributing flow fluctuations to upstream actions do not hold up under scrutiny when compared with Pakistan's own hydrological data, reservoir records, and operational realities. A more thorough assessment reveals a completely different picture: it is defined not by systemic deficit, but by abundant inflows, significant downstream releases, and long-standing structural limitations in water management.

The most notable feature of the 2025 hydrological cycle was a substantial surplus of water availability during the Kharif season (autumn, April-September). According to the Indus River System Authority (IRSA) of Pakistan, actual inflows reached approximately 122.36 million acre-feet (MAF), which was nearly 18 percent higher than the projected inflow of about 104 million acre-feet for Kharif 2025. Heavy rainfall across the basin further reduced irrigation demand and lessened pressure on provincial allocations. Such conditions fundamentally contradict claims of acute or artificially created water shortages.

Significant Releases into the Arabian Sea

An even stronger refutation of the water shortage narrative lies in the vast amount of water that ultimately flows downstream from Kotri into the Arabian Sea. During Kharif 2025, discharges below Kotri amounted to nearly 30.848 million acre-feet—approximately 71 percent more than the five-year average of 18.034 million acre-feet. Significant discharges into the sea continued during the lower-flow Rabi season (spring, October-March) of 2025 (about 3.6 million acre-feet). If the basin were truly facing a serious deficit, allegedly due to upstream interference, such large volumes of water would not have remained unused and would not have reached the sea. The data suggests limitations in storage infrastructure, flood management, and distribution efficiency within the lower basin itself.

Reservoir Behavior and Forecasts

Reservoir behavior during the same period also undermines claims of prolonged hydrological difficulties. As expected, the Kharif season began with relatively low storage levels, which is normal unless reservoirs are designed for storage accumulation. Subsequently, the combination of higher inflows and flood events quickly replenished the main reservoirs. By September 2025, storage levels reached almost 99 percent of capacity, creating a significantly stronger position of water availability for the Rabi 2025–26 season.

Prospects for Kharif 2026 remain stable. Projected inflows at border stations of about 103.3 million acre-feet for Kharif 2026, combined with carryover reserves estimated at approximately 2.3 million acre-feet—which is higher than both the previous year and long-term averages—indicate that the basin is entering a new cycle of relative hydrological comfort, not crisis.

Natural Factors and Hydropower Operation

Concurrently, recent attempts by Pakistan to present fluctuations in the Chenab River as proof of upstream manipulation ignore both hydrological realities and established operational practices of 'run-of-the-river' hydropower plants. Downstream flows, such as those at Marala, naturally depend on seasonal snowmelt processes in the Himalayas. Changes in winter snowfall, delayed melt, or cooler spring temperatures naturally affect flow levels at the beginning of the season. Such fluctuations are common in Himalayan river systems and cannot themselves be interpreted as evidence of deliberate intervention.

Operational dynamics at hydropower plants, such as the Baglihar Hydroelectric Power Station, have also been repeatedly misrepresented. Reservoir management in 'run-of-the-river' systems inevitably involves variable discharges related to silt flushing, maintenance requirements, power generation optimization, safety measures, and flood control protocols. Silt management is particularly critical in Himalayan rivers carrying heavy sediment loads. Thus, temporary operational adjustments during flushing or maintenance cycles are an integral part of the project's functioning.

International Oversight and Lack of Damage

It is important to note that the Baglihar project has already undergone rigorous international scrutiny. Pakistan itself initiated the application of dispute resolution provisions of the Indus Waters Treaty, leading to the appointment of a Neutral Expert in accordance with Article IX and Annex F. The Neutral Expert's decision in 2007 confirmed the main design and operational parameters of the project, rejecting most objections related to water levels and freeboard. It was confirmed that the project complies with the treaty provisions governing 'run-of-the-river' hydropower development.

Equally significant is the absence of any evidence of tangible downstream damage caused by alleged flow fluctuations. Accusations were largely based on selective imagery, isolated observations, and media narratives, rather than rigorous hydrological analysis establishing causality, economic damage, or quantitative agricultural impact. No specific evidence has been presented linking operational changes at upstream projects to sustained downstream difficulties.

Conclusions on Basin Issues

Furthermore, accusations of politically motivated manipulation overlook an important practical reality: any intentional interference with the operation of hydropower plants would entail not only direct economic costs for the upstream operator due to reduced energy generation efficiency but could also cause long-term harm to the station. One flushing cycle during the monsoon season at the Baglihar dam can lead to an estimated loss of about 150 million units of electricity generation and corresponding revenue. Such flushing operations are conducted by the operator solely for technical and servicing reasons. It is difficult to reconcile claims of deliberate violation with operational decisions that simultaneously reduce energy production and impose financial losses.

In summary, the available evidence leads to a clear conclusion. The Indus basin recently experienced higher-than-expected inflows, significant downstream releases, rapid reservoir recovery, and stable future forecasts. River flow variations remain within the bounds of natural hydrological processes and standard reservoir operations. The larger problem facing the basin is not speculative claims of upstream resource deprivation, but unresolved structural issues—limited storage capacity, sedimentation pressure, inefficient utilization, and broader water resource management constraints. Externalizing these internal management deficiencies through narratives of manufactured scarcity does little to solve the real long-term problems facing the basin.
