Affected by the landslide disaster that occurred on the Nepalese side on August 26, the Cuojian River in Nepal formed a weir lake near the confluence of the Przepuqiang Reservoir in China. As of the morning of August 27, the estimated water storage capacity was about 2 million cubic meters. According to forecasts, due to rainfall, the amount of water entering the weir lake in the next 3 days will be about 3 million cubic meters, and there is a high risk that it will collapse, which may cause another disaster in downstream areas such as the Geelong Port. At 13:00 on August 27, the Ministry of Water Resources initiated a flood prevention level IV emergency response for Tibet, instructing and supervising the Tibet Autonomous Region Water Resources Department to pay close attention to changes in weir stability, water storage volume and rainwater conditions, strengthen emergency duty, monitoring, forecasting and consultation and judgment, scientifically analyze the impact of the dam lake's collapse and flood, accurately grasp the distribution of people affected downstream, issue timely risk warnings, and request local authorities to transfer threatened personnel in advance to provide strong support for emergency treatment of weir lakes and rescue in downstream affected areas. The Ministry of Water Resources has dispatched an expert team to Jilong County in Tibet to assist and guide the emergency response to the dangerous situation in the weir lake, and the dispatched hydrological emergency monitoring team is carrying out on-site monitoring of water conditions.
