Lakes Gregory and Mackay, Western Australia20.2S 127.4E
Two lakes can be seen in this image of Western Australia: Lake Mackay (below) and Lake Gregory (upper left corner). The former is a large, ephemeral salt lake by the Great Sandy Desert, Gibson Desert, and Tanami Desert.
Lake Gregory (aka Paraku) is an inland drainage lake situated in north-eastern Western Australia between the Great Sandy Desert and the Tanami Desert. It is usually fresh water, but can become saline after a number of dry years. It has a fairly regular inflow of water and is considered to be a permanent lake.
