Foam crowns on the Kienbach are currently causing great concern to residents.
Since Friday, “bubble baths” have been forming, especially where the water falls.
The experts from the Lower Nature Conservation Authority and Water Management Office are taking a close look at the foam today.
Herrsching -
"It looks as if it were chemistry," says Angelika Preisinger.
The Herrschingerin has lived on Kientalstraße for 40 years, her property borders directly on the Kienbach.
That's why she always keeps an eye on the water.
For a year now, she has been observing foam forming during heavy rain, and again these days, she reports.
The foam shimmers yellowish and piles up on the stream steps like in a bubble bath.
She had already pointed out the foaming to the police and authorities on Friday.
samples were taken.
The lower nature conservation authority in the district office of Starnberg and the water management office in Weilheim take indications like this seriously.
After all, it can happen again and again that contaminants get into the water that have no place there.
A water test should provide information about this.
A joint on-site appointment has been agreed for today, says district spokesman Stefan Diebl.
Weilheim's head of department, Stefan Raab, will also be present at this meeting.
“We have to wait for the results.
We're a bit in the dark," he says.
At this time of year, a completely harmless cause could of course also be conceivable.
Because there is currently an increased pollen count.
In higher concentrations, pollen can cause foam to form, especially at small waterfalls where the water is also stirred up.
When pollen is high, the otherwise white foam turns yellowish.
Angelika Preisinger actually rules that out.
There was water pollution about two decades ago, she says.
"It looked the same." Back then, the foam would have piled up meters high.
"It's not pollen, it's fat," she says.
For a year now she has been observing this foam formation again and again during heavy rain events.
"There haven't been any trout swimming here for a year." She took pictures - these are from January and September.
"Pollen don't play a role there."
The representatives of the authorities from Weilheim and Starnberg hope to find out today what exactly is responsible for the foam formation in the Kienbach.
