Val de Bagnes Crisis: Dozens Evacuated Amid Ongoing Debris Flows

In a swift response to escalating debris flows in southwestern Switzerland, approximately 30 residents from Les Epenays village near Lourtier in Val de Bagnes have been evacuated. The emergency measure, implemented on Sunday, also included the evacuation of two farms in the Fregnoley area. Local authorities, led by Antoine Schaller, deputy secretary general of the Val de Bagnes municipality, confirmed that the evacuees will be housed elsewhere indefinitely, emphasizing that the timeline for return depends entirely on natural conditions.

The crisis stems from significant geological instability in the region, with cantonal authorities reporting that approximately one-third of the mountain slope has become unstable. This translates to an alarming volume of 30,000 to 50,000 cubic metres of loose material, which has doubled in volume upon reaching the bottom of the Fregnoley torrent. The situation has been exacerbated by recent storms, leading to continuous debris flows carrying a dangerous mixture of wood, mud, and large stones through the area.

The debris flows have severely impacted local infrastructure, necessitating the closure of the vital road link between Champsec and Lourtier for several weeks. Construction work on a protective gallery has been suspended until at least mid-July, with plans to reopen the 70-metre long covered section by December's end. The situation has also led to the permanent closure of the hiking trail between Les Epenays and Champsec, while a temporary emergency bridge was destroyed by recent mudslides, leaving only a pedestrian and cycle path connecting to Lourtier village.

Municipal and cantonal authorities are maintaining close surveillance of the situation, which is expected to remain tense for at least two weeks. Emergency response teams have constructed a new dam to manage debris flows, while excavators continue their work during calmer periods. The formation of a small lake in the area is being monitored, though currently poses no immediate danger. Authorities are implementing a comprehensive recovery plan, prioritizing public safety while working towards restoring essential infrastructure, particularly the crucial road connections that serve the affected communities.
