History

Between the late 1860s and the 1950s,

salt works A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The Salt pans are shallow and large of size because it will be easier for sunlight to travel and reach the sea water. Natural s ...

at Lake Beeac and other nearby lakes produced commercial quantities of salt. The Melbourne spice merchant Henry Berry established a salt works at Lake Cundare, just north of Beeac, in 1868 which produced salt by a boiling and crystallising process. The works produced a fine salt for domestic consumption under the label "Tower of London". Production ceased in 1895. Lake Beeac was the main lake in the area used for the collecting of naturally crystallised salt during the summer months. This process produced a coarse salt that was sold for agricultural and industrial purposes. Production depended on the weather: during the hot dry summer of 1921, 3000 tonnes were produced, but in a wet summer no salt at all could be collected. Commercial production ceased in 1954, by which time cheaper production elsewhere had made the Lake Beeac salt uneconomical.Houghton, pp. 22–25.
