Overview

• Reuters reported an undated Indian government analysis warning dry-season flows could fall by up to 85%, with potential diversion estimated at about 40 billion cubic meters—just over a third of annual flow at a key border point.
• Delhi is accelerating the Upper Siang multipurpose storage project, with NHPC moving survey materials under armed police in May and a July meeting led by the prime minister’s office to speed decisions.
• Operational proposals under review include keeping roughly 30% of the planned reservoir empty to absorb sudden surges, with projected storage around 14 billion cubic meters to help buffer seasonal shortages.
• Local opposition has turned confrontational near Parong in Arunachal Pradesh, where Adi community members attacked survey teams; at least 16 villages and about 10,000 people could be directly displaced, with far wider impacts claimed by community leaders.
• China says construction began in July on what it bills as the world’s largest hydropower complex on the Yarlung Tsangpo and insists it will not harm downstream states, as India’s S. Jaishankar pressed concerns with Wang Yi last week and experts flagged seismic and glacial lake outburst risks.
