The lake, the Wildmoossee, lies at 1,320 m on the Wildmoos plateau, not far from the Wildmoosalm restaurant. The Wildmoossee and the nearby lake, the Lottensee, are examples of a fascinating natural phenomenon. You can spend a nice day relaxing and swimming in the two lakes, but not always, as the water only appears periodically depending on the levels of snow melt and rainfall. The lakes just seem to appear from nowhere, right in the middle of the green meadows, larch and birch trees.
This aperiodic (irregular) natural highlight is most likely a complicated mix of the levels of spring rain and snow melt in the underground karst system. The ground beneath the lakes is probably heavily karstified, but the water system is sealed from below. Once the thaw begins in spring, the underground systems fill with water and the excess water floods the hollows in the meadows and forms lakes, which often disappear again after a few weeks. Interestingly, the water level often continues to rise after the thaw has ended and the water bubbles out from underground springs.
There have been many attempts to try to predict the appearance of the lakes, all of them
