Lake Bullen Merri


Lake Bullen Merri and it's smaller northern neighbour Lake Gnotuk are a pair of crater lakes near Camperdown in south western Victoria, Australia.
Lake Bullen Merri has brackish water quality whereas Lake Gnotuk is hyper saline.

Lake Bullen Merri

Lake Bullen Merri has a maximum depth of, 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. 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.
On the south side of the lake there is a yacht club and toilets. There is a boat ramp available for the boaties.

Lake Gnotuk

The smaller lake to the north of Lake Bullen Merri has a maximum depth of. The two lakes are linked by an overflow channel in the common wall at an elevation of 175 m. There is a 19th century record of water from Bullen Merri overflowing into Gnotuk.
Inside the crater of Gnotuk is Camperdown's sporting grounds. There is a 18 hole golf course, two cricket ovals, and an equestrian course for horse enthusiasts. The crater is 2 km across and although the lakes have the same level of their lake-beds the level of water is lower in Gnotuk. Lake shore terraces indicate previous higher levels and lake floor sediments and fossils show a record of past fluctuations in salinity, water level and climate.
There is no direct public access to the water edge of the lake.
