Lake Palčje is an
intermittent lake in a
karst basin in the
Inner Carniola region of Slovenia, north of the settlement of
Palčje. It is the largest among the
seasonal lakes of Pivka, with an average maximum water area of around 1 km2 (0.39 sq mi). The lake bed is at
groundwater level, so the amount of water depends on current
hydrological conditions. Usually, the lake fills after the heavy rains in late autumn and again in spring, with water present for around three months every year. This photograph shows Lake Palčje drained in autumn.
