The lake covers approximately , making it Victoria's largest
salt lake. It is located north of the town of
Sea Lake and northwest of
Melbourne. While much of the time the lake is dry, it is usually covered in about of water in winter. It is ancient, and probably formed by sand blocking the passage of Tyrrell Creek, a
distributary of the Avoca River, which feeds the lake.
Evaporation results in a layer of salt crusting on the lake bed, which is harvested by Cheetham Salt in
Sea Lake. The lake environment is host to Mallee
reptiles,
kangaroos,
emus, and the
white-fronted chat, an insectivorous bird. Thousands of
seagulls breed on small islands on the lake. Surrounding vegetation is made up of
saltbush and
samphire, which supports a range of wildlife. To the east, the
lunette contains significant Aboriginal relics. ==History==
