Pakistan Commissioner for Indus Waters Syed Muhammad Mehar Ali Shah said on Tuesday that he had written to his Indian counterpart regarding fluctuations in the flow of the Chenab River four times since last April — when New Delhi unilaterally decided to hold the Indus Waters Treaty in abeyance — but there had been no response thus far. Speaking at a seminar held in Islamabad to highlight the legal and constitutional framework of the IWT, he said he last wrote to his Indian counterpart last night over “significant fluctuations” in the flow of the River Chenab. The IWT allocates the eastern rivers — Ravi, Beas and Sutlej — to India, while the western rivers — Indus, Jhelum and Chenab — are largely allocated to Pakistan.
