Lakes Gregory and Mackay, Western Australia

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.

Eighty Mile Beach and Nearby Salt Marshes, Western Australia

Australia - March 5th, 2010

Eighty Mile Beach is the coastal edge of the arid, sedimentary Great Sandy Desert and the Canning Basin, in northwestern Western Australia, bordering the Indian Ocean. Extending in a curve northeast from Cape Keraudren (east of the De Grey River mouth) to Cape Bossut, it is about 85 miles (140 km) long, hence its name.

The beach, generally low and sandy but with an expanse of dunes in the area around Anna Plains, experiences a tidal range as great as 28 feet (9 m). It is bordered with salt and samphire (plant) marshes that extend inland. Here, the beach appears as a bright white line along the coast, while the marshy region is darker in color although still light in comparison with the rusty red terrain further inland.

Between the Great Sandy and Gibson Deserts in Western Australia lie several playa lakes, white in color. The largest is Lake Disappointment, near the image center. To the north lies the smaller Lake Dora, on the Rudall River. These bodies of water are ephemeral and frequently appear as white salt flats.

Moving northwest, another white area is visible: the light sands of Eighty Mile Beach, forming the coastline where the Great Sandy Desert approaches the Indian Ocean. It is one of the most important sites for migratory shorebirds, or waders, in Australia, and is recognised as a wetland of international importance under the Ramsar Convention on Wetlands.

Close to Eighty Mile Beach and included in the Eighty Mile Beach Ramsar Site is the Mandora Marsh, also known as Mandora Salt Marsh, a complex and diverse wetland system. It lies at the western edge of the Great Sandy Desert bioregion and within the Mandora Station pastoral lease.
