TREE NEWS update: China’s Ministry of Water Resources reported that latest drone imagery shows normal water flow in the upper and lower reaches of the former Purupeqiangzangbu barrier lake in Gyirong, Tibet, and in Nepal’s Cuojian River impact crater. Of 14 previously surveyed glacial lakes, 9 slightly shrank and 5 slightly expanded, with overall stability. A small landslide downstream has minimal impact on the river channel.
Ministry: Tibet Gyirong barrier lake flows normal, ice lakes stable
The confirmation of stable flows and minimal downstream impact reduces immediate hydrological risk in the Tibet-Nepal border region, which matters for local infrastructure and cross-border water management. The slight expansion of five glacial lakes, though within a stable overall picture, keeps longer-term climate-related hazards on the radar. Whether seasonal weather or seismic activity alters this stability is the key variable to watch, as drone monitoring appears to be the primary verification tool going forward.
