Wild Lake[2][3][4] (Slovene: Divje jezero) is a lake near Idrija in western Slovenia and a karst spring of the Vauclusian type.

[6] Water flows from the submerged cave in the southern shore of the lake, out of a steeply inclined tunnel, explored to a depth of 160 metres (520 ft) and length of 415 metres (1,362 ft).

[6][7] The discharge occasionally surpasses 60 cubic metres per second (2,100 cu ft/s).

[6] However, when the water level is low, there is no outflow from the lake.
