The Bac Khe 1 hydroelectric dam in Lang Son province has collapsed.

On the afternoon of October 7th, the Bac Khe 1 hydroelectric dam (Kim Dong commune, former Trang Dinh district) broke over a section of about 10 meters, causing water to flood the control center and downstream.

The dam broke at 2 PM, near the spillway. Initially, the crack was small, but it widened. Water from the dam overflowed downstream, causing the stream to rise rapidly, threatening residential areas along the stream banks, according to Mr. Nong Huyen, a local resident.

Mr. Pham Tuan Anh, Director of the Industrial Safety and Environmental Engineering Department ( Ministry of Industry and Trade ), said that authorities have not yet recorded any casualties. Some machinery and equipment have been affected.

The Bac Khe 1 hydroelectric power plant is located on the Bac Khe River, a tributary of the Ky Cung River, with a capacity of approximately 24 MW.

Affected by the circulation of Typhoon Matmo, Lang Son experienced heavy rainfall. From 7 PM on October 5th to 7 PM on October 6th, Mau Son recorded 205 mm of rain; from 7 PM yesterday to 7 AM today, Quyet Thang recorded 195 mm. Water flowing into the hydroelectric dams pushed water levels up, putting pressure on the dam embankments.
