StandardDetailedBy ChemistryMineral Photos (3)Site Photos (5)MapsSearch Google

Lake Bullen Merri occupies a large maar crater of Quaternary age. Its clover leaf shape suggests that it was formed by three craters coalescing. The lake measures 3.2 km by 2.8 km, and the brackish lake water is about 60 m deep. Lake Bullen Merri and the nearby Lake Gnotuk together form a site of international significance listed in Victoria.
