Bílá Desná dam failure commemoration

Overview

In September 2026, events were held to commemorate the 110th anniversary of the Bílá Desná dam failure in the Jizera Mountains. The disaster occurred on September 18, 1916, when the dam, completed in 1915, collapsed and sent a massive surge of water, debris, and stones into the valley. The catastrophe resulted in the deaths of between 62 and 67 people and destroyed various structures, including homes, a sawmill, and glassworks.

Technical research indicates the collapse was likely caused by insufficient geological surveys, as the dam was constructed on compressible gravel deposits and a deep tectonic fault, leading to internal erosion.

The anniversary commemoration on September 19 drew approximately 3,000 attendees and featured cultural performances. The event was a collaborative effort between the towns of Desná and Albrechtice v Jizerských horách, alongside several regional environmental and water management agencies.

Following the disaster, the site—often referred to as ‘Protrženka’—has transitioned from a place of tragedy into a significant tourist destination. While remnants of the dam and a sluice tower remain in the forest, the valley has undergone revitalization through local improvements. The area now attracts approximately 200,000 tourists annually, representing a fourfold increase compared to 2015.
