 By 1910 there were at least three lease-holders scraping thousands of tons of salt from evaporation pans when the lake dried up – usually in December.In 1913, the Australian Salt Company was incorporated and held all the lake leases until 1971, when the company became a wholly owned subsidiary of Cheetham Salt Company Limited – now Cheetham Salt Limited, Australia's largest producer and refiner of solar salt.Efficiency of transportation was improved in 1926 after a 9 km (5.5 mi) branch line was built from the nearby Salisbury railway line, enabling transport directly to Port Adelaide.
