Dead fish in the Horhäuser bathing lake: Fire brigade on a large scale!
On Thursday morning, September 15, 2025, a worrying sight was discovered in the Horhäuser bathing lake in Theres, Hassberge district: a large number of dead fish were swimming in the water. The water warden discovered the dead fish shortly after 9:35 a.m. and reported that both the oxygen content and the pH value of the water were not within the normal range. These alarming values were also confirmed by the river master of the Bad Kissingen water management office. Unfortunately, this meant the end for the affected animals as a result of a dramatic change in the lake's ecosystem, which raised alarming questions.
The incident led to a huge effort by local fire departments and other helpers, who didn't hesitate for long. They immediately began pumping the water to bring new oxygen into the water. This measure continued for hours and extended into the early hours of Friday. However, there was no evidence of contamination or foreign discharges, which makes it a little easier to investigate the cause.
Causes and measures
The change in weather was identified as the main cause of the lake “tipping”. Sudden changes in the weather can have drastic effects on oxygen levels in water bodies. The fire department and helpers took this challenge seriously and worked hand in hand to solve the problem. The dedicated emergency services showed once again how important cooperation within the community is in crisis situations. The volunteers' commitment was greatly appreciated by the community, and many are grateful for the quick response and action taken.
However, the situation paved the way for a larger discussion about water quality in the region's waters. Such incidents should encourage those responsible to carry out regular checks and take preventive measures to avoid similar incidents in the future. One can only hope that lessons are learned from this episode and such tragedies can be prevented in the future.
Regional issues and other incidents
Although the Horhäuser bathing lake is the focus of interest at the moment, there are also other events in the region that deserve attention. In Schönau an der Brend, for example, a power distribution box was damaged, while in Bad Bocklet in the Steinach district, the plants on a grave were vandalized. A property wall was also damaged in Dingolshausen, which is more than just a minor annoyance for the affected residents.
This incident in the Horhäuser bathing lake clearly shows that nature is a fragile balance that must be carefully monitored. Those responsible in the region are now faced with the task of not only regenerating the affected waters, but also ensuring the safety and well-being of citizens.
