The water level fluctuates by about 2 m. The highest level is in early summer. The lake is of glacial origin and lies in the middle of the karst world in the Julian Alps.

The lake is rich in life. It is home to more than 40 different plants and 24 different animals. Its most common inhabitants are mountain lizards (navels) and crabs.
