Artificial Lake Forms After swiss Glacier Collapse, Flood Threatens Valley
Updated May 29, 2025
An artificial lake is growing in southern Switzerland following the collapse of the Birch Glacier, triggering concerns about potential flooding. Swiss authorities are closely monitoring the situation after the glacier’s collapse on Wednesday, wich also largely destroyed the village of Blatten.
The newly formed lake is expanding rapidly,prompting fears of downstream flooding in the Lötschental Valley. Antoine Jacquod, a security official for the Canton of Valais, told Keystone-ATS news agency that officials are working to assess the lake’s size. He noted a “serious risk of an ice jam” that could block the Lonza River,further exacerbating the flood threat.
As a precaution, 16 residents were evacuated from two villages downstream. Raphaël Mayoraz, who is in charge of natural hazard management, described the blockage on the Lonza River as “like a mountain,” creating a lake that continues to grow. An artificial dam was preemptively emptied to accommodate the expected surge of water.
“Today we will try to assess it’s [the lake’s] dimensions,” said Antoine Jacquod, a civil and military security official for the Canton of Valais.
Geologist Marcos Buser warned of the potential for debris flow to travel kilometers down the valley if the dam were to fail. The Valais government has requested assistance from the army, including pumps and clearing equipment, though the timing of intervention remains uncertain, according to Jacquod.
The glacier collapse has left one person missing. The missing individual, a 64-year-old local resident, was reportedly in the affected area when the incident occurred.A search and rescue operation involving rescue specialists and a drone with a thermal imaging camera has so far been unsuccessful.
What’s next
Authorities will continue to monitor the artificial lake and the Lonza River, with further evacuations possible if the situation worsens. The focus remains on preventing a major flood event and locating the missing person.
