A rapidly expanding dammed lake above a Nepal-Tibet flood zone poses a severe new threat to Gyirong Port, where hundreds of people remain unaccounted for following an initial catastrophic surge.Formed by mudslides near the junction of two rivers, the blockage sits about 11 miles upstream of Rasuwagadhi and has created a 27-acre lake, according to Nepal's National Disaster Risk Reduction and Management Authority (NDRRMA). China's Ministry of Water Resources estimated on Aug. 27 that the lake currently holds roughly 2 million cubic meters (528 million gallons) of water. Fueled by incoming rain, it is expected to absorb another 3 million cubic meters (793 million gallons) over the next three days.A 27-acre lake was formed roughly 18km upstream of the Rasuwagadhi border point, following mudslidesThe situation is increasingly precarious. The ministry warned that the lake is already overflowing and faces a high risk of a sudden release that could once again inundate Gyirong Port and communities downstream. Drone reconnaissance conducted by fire and rescue personnel - and reported by the state-run Xinhua News Agency on Aug. 27 - confirmed the danger, revealing that the lake's surface continues to expand with water levels visibly higher than the day before.In response to the mounting threat, Nepalese authorities have urged all residents, travelers, and rescue personnel along the Bhote Koshi River corridor to completely avoid riverbanks and other high-risk zones.This secondary crisis emerges as the toll from the first flood continues to rise.🚨🚨🚨#China alerts new barrier lake forms at #Nepal rivers confluence, posing high breach risk over next 3 days.
