Lake Mackay is the fourth-largest lake in Australia, covering 4737 It’s located on the border of Western Australia and the Northern Territory.

Like many salt lakes in the region, Lake Mackay fills up only with seasonal rainfall. The lakes are rarely deeper than a few metres, and may be as shallow as 50cm.

Named after explorer Donald George Mackay – who, along with his brothers, was the first to cycle around Australia – Lake Mackay is only eclipsed in size by Kati Thanda–Lake Eyre, Lake Torrens, and Lake Gairdner, all in South Australia. However, because of their ephemeral nature, the volumes of some of these salt lakes change by large amounts.
