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.

Two ephemeral lakes are visible in this image of arid Western Australia. The larger of the two, Lake Disappointment, appears as a white salt flat near the center. The other, smaller body of water, Lake Dora is located to the North, occasionally fed by the Rudall River.

The surrounding desert terrain is part of the Great Sandy and Gibson Deserts. The Great Sandy Desert is a 360,000 km2 (140,000 sq mi) expanse in northwestern Australia. It is a flat area between the rocky ranges of the Pilbara and the Kimberley.

To the southeast is the Gibson Desert, which is about 155,000 square kilometres (60,000 square miles) in size. It lies between Lake Disappointment and Lake Macdonald along the Tropic of Capricorn. The Gibson bioregion includes extensive areas of undulating sand plains and dunefields, low rocky/gravelly ridges and substantial upland portions with a high degree of laterite formation.

While the Fitzroy River releases tan sediments into King Sound on the northern coastline of Western Australia, several other bodies of water have a whitish color.

Lake Argyle, upper right quadrant, appears silvery white due to sun glint. It is Australia’s second largest artificial lake by volume and is part of the Ord River Irrigation Scheme. To the south, in the lower right quadrant, Lake Mackay also appears whitish, although this is due to salts and other minerals carried to the surface by evaporation.

West of Lake Mackay are the Rudall River, which connects to the seasonal salty Lake Dora. South of those two bodies of water is Lake Disappointment, an ephemeral salt lake.

The Rudall River, appearing as a tan streak through the red landscape, is an ephemeral river in the Pilbara region of Western Australia. The entire length of the river is located within the boundaries of the Rudall River National Park, the largest national park in Australia.

The Rudall River occasionally brings water to Lake Dora, a seasonal salt lake. It lies between the vegetated sand fields of the Great Sandy and Gibson Deserts. Here, the seasonal lake appears to contain water.

South of Lake Dora is another ephemeral salt lake, called Lake Disappointment. The lake, which is saline, is home to many species of waterbirds.

Continuing south, yet another ephemeral lake, Lake Carnegie, comes into view near the bottom of the image. It fills with water only during periods of significant rainfall. In dry years, it is reduced to a muddy marsh.

Lake Disappointment and Lake Dora - January 22nd, 2009

This remote part of Western Australia includes two salt lakes: Lake Disappointment (below) and Lake Dora (above).

Lake Disappointment is an ephemeral salt lake that is home to many species of waterbirds. It was named by the explorer Frank Hann in 1897.  He noticed creeks in the area flowed inland, and followed them expecting to find a large fresh water lake. To his disappointment the lake turned out to be salt, and subsequently it was named Lake Disappointment.

Lake Dora, on the other hand, is a seasonal salt lake. It lies between the vegetated sand fields of the Great Sandy and Gibson Deserts. The Rudall River occasionally brings water to Lake Dora.

About 1252 km northeast of Perth, north of Lake Disappointment and surrounding Lake Dora is the Rudall River National Park. It is the second largest national park in Australia and one of the largest in the world.
