Grüner See (Green Lake) is a lake in Austria. During the winter, the
lake is only 1–2 m deep and the surrounding area is used as a county
park. However, during the spring, when the temperature rises and the
water melts the basin of land below the mountains fill with water.
The lake is popular among divers who can observe the green meadows in
the edge zone of the lake particularly in June when the water is at its
highest. A bridge and a bench can also be found underwater.
