@dailymail: China has warned that a newly formed barrier lake near the Nepal-Tibet border could overflow and unleash another major flood downstream. Around 2.5 million cubic meters of water had collected behind the debris dam by Friday, with more rain and millions more cubic meters expected to enter the lake. Authorities have deployed engineering teams and drones to monitor water levels and prepare for a possible breach, although officials later said the immediate risk had been brought under control. The warning comes after a deadly flash flood hit the area on Wednesday, with hundreds of people reported dead or missing across Nepal and Tibet. #news #nepal #tibet #china
