Lake Cerknica (Slovene: Cerkniško jezero, German: Zirknitzer See) is an intermittent lake near Cerknica in Inner Carniola, a region of Slovenia. When full, it is the largest lake in the country. It lies in the southern part of Cerknica polje. The surface of the lake can reach up to 38 km² and the surface level varies from 546 to 551 metres above sea level.

Lake Cerknica is an important wildlife resort, especially as a nesting place for many bird species. It is therefore a part of two Natura 2000 areas of protection[1] and is the focus of Notranjska Regional park which covers additional Natura 2000 areas in the broader region.[2]

[edit] Research history

Strabo in his Geography (7.5) mentions a "marsh called Lougeon" (helos Lougeon kaloumenon) which has been identified with Lake Cerknica[3], Lougeon being Strabo's Greek rendition of a local toponym, perhaps of Illyrian origin. It is Romanized as Lugeum. In 17th century, Slovenian polymath Janez Vajkard Valvasor described the lake in his letter to the Royal Society which was later published in society's Proceedings. He proposed a model of filling and emptying the lake, based on Descartes' mechanics.[4]
