==Lake Bullen Merri==

Lake Bullen Merri has a maximum depth of {{convert|66|m|abbr=on}}, with a clover leaf outline indicating that it was probably formed by two overlapping maar volcanoes. The lake is depicted in work by Eugene von Guerard.[http://www.kanawinkageopark.org.au/wp-content/uploads/2010/03/LakeBullenMerri.pdf Lakes and Craters Precinct:Lake Bullen Merri], Kanawinka Geopark The edge of the lake was marked by a stone in the late 1800s by James Dawson; from this and von Guerard's painting, it can be deduced that the level of the lake has dropped considerably in the last 100 years.{{cite web|url=http://science.uniserve.edu.au/school/quests/ozvolcs/camperdown.html|title=Volcanic landforms in the Camperdown area of Victoria|work=UniServe Science|date=|access-date=16 June 2007}}

On the south side of the lake there is a yacht club and toilets. There is a boat ramp available for the boaties.
