Regarding the Bac Khe 1 hydropower dam break incident, on the afternoon of October 9, Mr. Hoang Ngoc Hung, Chairman of the People's Committee of Tan Tien commune, Lang Son province confirmed that the current water level at the Bac Khe 1 hydropower plant reservoir has decreased; the water flow to the dam is about 1,130 m3/s (on the afternoon of October 7 it was more than 1,570 m³/s), so the amount of water flowing through the break has also narrowed a lot.

Because there is no more rain in the area and surrounding areas, the water flow to the dam has also decreased, the water color in the lake is no longer cloudy yellow and has turned light yellow.

“Since the incident, the whole commune has not recorded any damage to people, property or crops. Although the water level has decreased, the People's Committee of the commune continues to monitor and supervise the scene to promptly detect signs of cracks and breaks on the dam line, report to the authorities according to regulations; continue to coordinate with relevant units to handle and overcome the incident to ensure the safety of people's lives and property", the Chairman of the People's Committee of Tan Tien commune added.
