Lake Corangamite /kəˈræŋɡəmaɪt/, a hypersaline endorheic lake, is located near Colac in the Lakes and Craters region of the Victorian Volcanic Plains of south-west Victoria, Australia. The lake's 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 square kilometres (89 sq mi) with a circumference of 150 kilometres (93 mi). It forms part of the Ramsar-listed Western District Lakes wetland site. The indigenous name of the lake is recorded as Kronimite.
