The rainfall of recent weeks has not had a negative impact on the water quality of Lake Constance. This is not least due to the fact that the wastewater infrastructure in the entire region is in very good condition.

The water level of Lake Constance is still unusually high, with the gauge in Bregenz currently showing 4.95 meters, which is 66 centimeters higher than the long-term average. In recent weeks, however, not only immense amounts of water have been washed into the lake, but also exorbitant suspended matter loads, which is why the Vorarlberg shore areas in particular, where the largest tributaries are known to be located, are still noticeably cloudy in many places.

However, there is no need to be afraid of jumping into the cool water, as the water quality is excellent. Although there may be a local increase in bacterial contamination after heavy rainfall, this usually dissipates very quickly - especially when the sun is shining and the UV radiation is correspondingly high.

Around four billion euros have been invested in wastewater treatment in the Lake Constance catchment area in recent decades - these investments have definitely paid off.
