Lake Bullen Merri has a maximum depth of 66 m (217 ft), with a clover leaf outline indicating that it was probably formed by two overlapping maar volcanoes.

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.

On the low-lying land between the two lakes is Camperdown's major sporting complex.

There is an 18-hole golf course, two cricket ovals (one with a turf pitch), an extensive equestrian course, tennis courts and a bowling green.
