Grüner See Natural Gem
It fills with crystal-clear spring water from the snowmelt on the mountains. The height of the water level depends on the amount of snow received during the winter and also depends on the precipitation.
The water level slowly recedes until autumn. In the winter, the water in the lake disappears almost completely. This cycle can take place annually only because nature and the environment are still in order in Styria. The animal and plant world here is still able to "REGENERATE" and "RECOVER".
