The court ruled. The gates didn't.

When I wrote about the Chenab last month, the argument was still partly inferential. The Marala hydrograph for April and early May showed a pattern of sharp surges, sustained depressions and near-vertical drops that no rainfall or snowmelt signal could explain. The conclusion was cautious but clear: this was not a river reacting to weather. It was behaving like a system being operated. What was missing was a ruling that said, in binding legal terms, what that operation was actually doing to Pakistan’s rights. On 15 May, that ruling arrived.

The Permanent Court of Arbitration, convened under the Indus Waters Treaty’s dispute resolution mechanism, issued a binding supplemental award holding that India must justify maximum pondage volumes against actual hydrological conditions and realistic operational need, not engineering assumptions. It built directly on the tribunal’s August 2025 Award on Issues of General Interpretation, which confirmed that India must “let flow” the waters of the western rivers for Pakistan’s unrestricted use, and that hydropower exceptions must be read narrowly, not stretched through operational practice. India was not in the room for either ruling. The concrete, meanwhile, has continued to pour.

Rasheed grows cotton in Toba Tek Singh. He has no idea any of this happened. What he knows is that his sowing window runs ten days in the third week of May, an entire season’s income folded into that narrow band, and that this year those days fell between a week when the channel ran nearly dry and a week when it flooded before his fields could absorb a drop.

The telemetry now confirms what April suggested. Through the first ten days of May, the precise window that decides a farmer’s year, the Chenab at Marala........
