[1] During winter, the lake is only 1–2 m (3–7 ft) deep and the surrounding area is used as a county park.

[citation needed] However, in spring, when the temperature rises and snow melts, the basin of land below the mountains fills with water.

[citation needed] The lake reaches its maximum depth of around 12 m (39 ft) from mid-May to June and is claimed to look the most beautiful at this time.

[citation needed] The lake supports a variety of fauna such as snails, water fleas (Daphnia pulex), small crabs, fly larvae, and different species of trout (Salmo).

[2] Because of the spike in tourist visits that has occurred and expected damage to this sensitive environment, the use of this lake for all watersports activities has been prohibited since 1 January 2016.
