Australia – March 26th, 2013

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.

Australia – March 10th, 2013

Lake Dora, visible in the upper left quadrant of this image of Western Australia, is a seasonal salt lake that lies between the vegetated sand fields of the Great Sandy and Gibson Deserts. The Rudall River occasionally brings water to Lake Dora.

The Rudall River is an ephemeral river in the Pilbara region of Western Australia. Its headwaters lie below the Watrara Range near Island Hill and flow eastward until it discharges into Lake Dora. Here, Lake Dora’s water levels appear high, and several large pools of water can be observed along the river’s course, due to heavy rains from Tropical Cyclone Rusty (17S). Lake Disappointment, in the lower left quadrant, also shows higher-than-usual water levels.

Australia – March 4th, 2013

Lake Dora (above) and Lake Disappointment (below) are two salt lakes in Western Australia that are often quite dry, only filling when there is extensive rainfall. Here, both lakes show the presence of water after heavy rains from Tropical Cyclone Rusty (17S) in late February and early March.

Lake Dora lies between the vegetated sand fields of the Great Sandy and Gibson Deserts, and occasionally receives water via the Rudall River. Lake Disappointment an ephemeral salt lake that typically remains dry except during very wet periods such as the 1900 floods and in many recent tropical wet seasons since 1967. It is at the northern side of the Little Sandy Desert and is also partially surrounded by sand dunes.

Australia – March 10th, 2013

Tropical Cyclone Rusty (17S) brought heavy rains and flood warnings to northwestern Australia in late February and early March 2013. The rains caused Lake Disappointment, a large but usually dry saline lake in the Gibson Desert, to fill with water. Despite its saltiness, Lake Disappointment provides a refuge for many species of waterfowl.

Australia - December 18th, 2011

This image shows the border area by Australia’s Northern Territory (right) and Western Australia (left). Visible in the lower part of the image is the Gibson Desert, which covers a large dry area in the state of Western Australia of about 155,000 square kilometres (60,000 sq mi) in size.

Large portions of the desert are characterized by gravel-covered terrains covered in thin desert grasses and it also contains extensive areas of undulating red sand plains and dunefields, low rocky/gravelly ridges and substantial upland portions with a high degree of laterite formation. The sandy soil of the lateritic buckshot plains is rich in iron.
