The Desná dam, also known as the Rifle, is a water work on the White Desná in the village Albrechtice v Jizerských horách. It was built between 1912 and 1915 and gained tragic glory after the breach of the dam in 1916, which claimed many victims.

The impulse for its construction was devastating floods in the foothills of the Jizera Mountains in the second half of the 19th century. The most significant of them was the flood in July 1897, when on July 29 the weather station in Nová Louka recorded precipitation of 345,1 litres per square metre in 24 hours. On the Czech side, this disaster claimed 120 victims and caused damage of millions of Austrian crowns. The need for flood protection measures led to the establishment of water cooperatives and cooperation with Professor Otto Intz, who lectured in Liberec on the valley dams. After his death in 1904 the project was completed by Prague engineer Wilhelm Plenkner.

Plenkner designed a dam system on the White and Black Desnas, which was intended to connect the bridge for the transfer of water. Both works were designed as ground-filled dams, as the rock massif for the foundation of the gravity dam lay too deep under a layer of sediment. The dam on White Desná had a crown of 172.8 metres in length and a width of 5.2 to 5.5 metres, while it measured 54 metres in heel. The height of the crown above the terrain and the maximum depth of the tank were 17.5 metres. A tank of 400,000 cubic meters flooded an area of 8,4 hectares.

Construction on White Desná was started by Franz Schön and sons on 17 October 1912. In the bottom of the valley was built a concrete bridge on two longitudinal concrete passports based on wooden piles. The work was done under unfavourable conditions; Intense rains damaged the work and the First World War forced austerity measures that reflected in the quality of the construction. The work was completed in September 1915 and collaborated in November of the same year.

The disaster occurred on September 18, 1916. In the afternoon, two forest workers recorded a spring coming out of the dam. Due to the increasing intensity of water leakage and fear for life, the seals have been partially opened. Seventy minutes after the first observation, the dam was ruptured. Water meat, which helped as a ram logs from a nearby saw, destroyed 33 houses, damaged another 69 and left 307 people without shelter. The disaster balance was 67 casualties.

The cause of the accident was considered inappropriate material and insufficient compaction of the dam body. The 1996 study refuted these reasons and identified the water leak as a cause which was caused by insufficient sealing in the project. The subsequent trial lasted 17 years and ended in the acquittal of the defendants. The Court found that the cause was a geological disorder at a depth where the standards at the time did not require test probes to be carried out.

The original water work was preserved from the slide tower and the stol to the Soush dam. The stol serves as a winter playground for eleven species of bats and since 2005 it has been declared a European important location, which means a ban on entry. There is a learning trail with six stops for visitors in the area.

Instead of the Rifle, it resembles a tragic combination of technical failures and natural influences. It is an important location for understanding the history of water management in a region worth visiting.

Welcome to a place that carries deep calm, but also a strong memory of the great unrest and tragedy of the past. You're standing right in front of a place people in these mountains often call the Rifle. You may now be surrounded by silence or just a splash of water, but try to imagine how much this place has changed in the past. Before your eyes, there is an open space where a human quest for protection and security has clashed with the untamed and destructive force of nature. This water structure, known as přehrada Desná, is not just an ordinary piece of technology, but a monumental witness to human efforts, which ended in an unexpected and painful end. Feel this atmosphere, feel the weight of history that took place here.

Let us now go back in time together and understand why such a fundamental work has been chosen here. To understand the meaning of this dam, we need to look at the events that took place in the second half of the nineteenth century. The region of the Jizera Mountains at that time suffered constant and very devastating floods. The water came unexpectedly, destroying houses, fields and, above all, endangering the lives of people living in the valley. One of the most terrifying and most important moments that changed the people at the time irrevocably was the July of the year a thousand eight hundred ninety-seven. At that time, an incredible storm spread over the mountains, and the rainfall was so extreme that over three hundred forty-five litres of water fell on each square metre of land in just 24 hours. Such a force of water was absolutely intolerable for the people of the time, and it caused enormous fear throughout the region. It was this tragic experience and the need to protect people's lives that led to the decision to build a Great Dust River dam. The goal was to create a solid barrier that could contain excess water and protect the following valleys from future floods.

Now pay attention to how this magnificent work was created. The entire construction process was extremely demanding and required great courage and expertise. The construction started in the year one thousand nine trăm twelve and lasted several years until it was completed in the year one thousand nine hundred fifteen. The architect Wilhelm Plenkner oversaw this whole complex project. Now, when you look at this place, try to imagine in your mind the enormous work, the technical precision and the faith in the success that people were putting into the building at that time. Every stone, every part of this structure was meant to serve as a symbol of safety and human triumph over the dangers of nature. The architecture of this water work was to prove that man could control even the wildest elements if he used his intelligence and strength to do so.

But notice how fragile this faith can be. History tells us a story that is full of sadness and unexpected twists. Although the dam was finished and people could finally feel relief, fate was very cruel. Already in the year one thousand nine trăm sixteen, that is, shortly after the construction was completed, the worst thing that people could have imagined at the time. The dam couldn't hold the water pressure and it ruptured. This event was not just a technical failure, it was a complete disaster that hit people's hearts. The passage of a huge mass of water caused devastating damage and, most painful, the lives of many innocent people. What was supposed to be a protection and rescue for the whole area, in a moment, turned into a cause of great suffering. This tragedy remains in mind as one of the darkest chapters in the history of this region.

While you're looking around now, you might wonder why that happened. There's something deeply mysterious and terrifying about it. How is it that a work built with the intent and supervision of competent experts such as Wilhelm Plenkner has failed so early and so devastating? This mystery, this contrast between great ambition and sudden destruction, is what makes this place so special. It is a reminder of how much our existence depends on powers that we often cannot fully control. This dam, now associated with the concept of Rifle, serves as an eternal memento not only of the power of water, but also of the fragility of human plans.

But now we will not just keep you with sad memories. We suggest you continue your walk and explore the surrounding countryside. Take a look at the terrain you see here, and try to reconstruct in your imagination the way the water rolled down that fateful year. Let the beauty of the Jizera Mountains consume you, which are now calm and harmonious again, and feel the contrast between today's calm and the stormy history that took place here. Every step of this place can bring you a new perception of history and a deeper understanding of how much our world around us changes. Thank you for choosing to visit this memory and devote your time to her story. We wish you a beautiful and inspiring journey along the paths of our mountains. Goodbye.

Tips for visitors

The best time to visit is when nature is the most colorful, for example autumn, which gives the place a melancholy atmosphere. For the best light in photography I recommend morning or late afternoon hours, when shadows highlight the structure of the destroyed water work.

You can reach the place by car or use public transport.

Due to the mountain position, emergency condition and weather, we recommend to bring with us fixed shoes, waterproof clothes and plenty of fluids. Monitoring the weather forecast will ensure better visibility.

It is important for families with children to be careful. Due to your emergency condition, only move on safe and determined routes. There are no other specific objectives to visit in the vicinity.

Seasonal recommendations

In the spring, the water level is rising rapidly. Nature begins to grow green, but the air remains cold and wet. I recommend you wear waterproof shoes because the roads can be very muddy. The best is to visit the place in the morning when the light is delicate and refreshing.

The summer months bring a dense shadow of forests and bright sun that highlights the grey concrete structure. The atmosphere is full of energy, but due to the large number of visitors it is advisable to come very early in the morning. Dress light and breathable substances, but take care of your safety because of the emergency condition of the work.

In autumn, the surroundings are coloured in gold and red tones, creating a melancholy contrast with the abandoned appearance of the water works. There is often a fog that gives the place mystery. Suitable are layered dresses and a visit in the afternoon when the low sun lights up beautifully to the details of the construction.

In winter, snow fills the landscape and frost freezes the surfaces, stressing the roughness of this place. Deny is short, so plan your trip to the morning to use enough light. Hot clothes and tight soles are essential to ensure that the drop on the frozen surface is minimal.
