The Indus Waters Treaty (IWT) is under strain: India has reportedly stopped providing detailed river-flow data to Pakistan as required under the agreement.
According to Pakistan’s Senior Secretary at the Ministry of Water Resources, India now only indicates whether river flows are “high” or “low” but omits quantitative measurements of discharge (cusecs).
India’s data-sharing channel has also changed: rather than passing information via the Indus Waters Commission (the treaty-mandated body), it is now using diplomatic notes through the foreign office. Pakistan regards this as a direct violation of the IWT.
As a result, Pakistani authorities say they have been forced to rely on satellite imagery—with error margins of up to about 25 %—to estimate flows, increasing risk of miscalculation, especially in flood early-warning and water-management.
