Lake Corangamite is Victoria's largest natural lake, located near Colac in south-west Victoria, Australia in the Lakes and Craters region of the Victorian Volcanic Plains. The lake is hypersaline, and salinity levels have increased dramatically as the lake level has dropped in recent decades. It is Australia's largest permanent saline lake, covering approximately 230 km2 with a circumference of about 150 km. It forms part of the Ramsar-listed Western District Lakes wetland site.
