Lake Zug is suddenly blood red – that’s behind it
In some places, Lake Zug has suddenly been red since Christmas. The police warn and explain what’s behind it.
Lake Zug is suddenly red.
Christmas fright in central Switzerland. Anyone who is out and about on Lake Zug at Christmas suddenly only sees red. The lake is completely discolored around the Landsgemeindeplatz in Zug, almost a bloody colour.
The discoloration is not about water pollution, as reported by the Zug police on Twitter. Rather, the Burgundy algae appeared in the waters off Zug.
There is basically no danger to humans. Nevertheless, there is only a partial all-clear. Because for animals, especially dogs, the algae can be dangerous “depending on the concentration,” it says. Therefore, caution is advised.
In recent years, there have been repeated tragic incidents involving animals bathing in algae-polluted lakes. In June, a dog poisoned by cyanobacteria died in the canton of Neuchâtel. In the vernacular, these are also called blue-green algae.
In May, the Zurich cantonal police warned of the deadly blue-green algae that were spreading in Lake Greifen at the time. Two dogs died after a walk at the Greifensee. (zis)
