Emergency in the chalk lake Hemmoor: diver fights for her life!

A dramatic incident occurred at the Kreidesee in Hemmoor, which has recently been making sad headlines. On June 20, 2025, a group of four divers struggled with health problems while surfacing at a depth of around ten meters. Those affected, including a 61-year-old diver from North Rhine-Westphalia, immediately alerted the emergency doctor and rescue service when they reached the surface. According to [cnv-medien.de](https://www.cnv-medien.de/landkreis-cuxhaven/hemmoor/notfall-im-kreidesee-hemmoor-rettungshubschrauber-fuer- Tauchgruppe-im-satz.html), the rescue workers were quickly deployed. An ADAC rescue helicopter, “Christoph Hansa” from Hamburg, was requested for preventative treatment of the diver, who was then flown to a Hamburg clinic.

The other three divers were taken to nearby hospitals after an initial examination. It is worrying to hear that several diving accidents have already taken place in Kreidesee this year. Just a month ago, a 34-year-old man from the Netherlands lost his life after an emergency climb. In addition, serious health problems among divers are repeatedly reported. It appears Hemmoor has become an unfortunate hotspot for diving accidents, increasing concerns about diving safety.

Another tragic incident

As nordsee-zeitung.de reports, another fatal incident occurred at the same location. A 30-year-old diver from Grießheim near Darmstadt died during a course in the Kreidesee. Despite the immediate and professional efforts of the rescue workers, who deployed numerous teams on site, the diver could no longer be saved. The exact circumstances of her death are currently unclear and police investigations are ongoing.

These sad events come in the context of worrying statistics about diving accidents. The Association of German Recreational Divers (VDST) has been keeping a record of such incidents for twelve years in order to better understand the general conditions and frequency of diving accidents. According to [sport Taucher.net](https://sport Taucher.net/2019/11/07/unfall-analyse/), interesting patterns have been identified in recent years: The frequency of accidents increases especially from the age of 40 and accident-prone situations often occur among experienced divers, with many accidents being caused by panic, failed decompression or emergency ascents.

Safety in diving

It is therefore of the utmost importance for all divers to constantly inform themselves about safety guidelines and maintain healthy procedures. The Chalk Lake accidents should serve as a serious reminder not only of the local conditions, but also of the risks that diving poses. The joy of diving should never come at the expense of safety and health, and it is time for every diver to develop a good knack for their own safety.

The situation around the Kreidesee illustrates how important it is to communicate with one another and to be attentive. We hope that the injured will recover quickly and that such tragic incidents can be prevented in the future. In the fascinating world of diving, skill and safety must never be lost sight of for a moment.
