Wild Lake[2][3][4] (Slovene: Divje jezero) is a lake near Idrija in western Slovenia and a karst spring of the Vauclusian type.[5] The lake is the source of the Jezernica River, a tributary of the Idrijca and, at 55 metres (180 ft) long, the shortest river in Slovenia.[6] Water flows from under the ground and through a steeply inclined tunnel, explored to a depth of 160 metres (520 ft).[6] 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.[6] In 1967, the lake was protected as a natural monument. In 1972, it was arranged to be the first Slovenian natural museum.[5]
