Higher Water Levels in Rudall River, Australia

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.

This image focuses on the northern coastline of Western Australia. The contours of the portion of the coast in the upper right quadrant are highlighted by sun glint. Several rivers flow into the Indian Ocean along this section of the coast: the Mitchell River, the Roe River and the Prince Regent River.

At the end of the area highlighted by glint is King Sound. Sediments from the Fitzroy, Lennard, Meda, Robinson and May Rivers flow into the sound and then into the Indian Ocean.

Another river, the Rudall River, is visible further inland in the lower right quadrant. It appears white in color and is connected to Lake Dora, with Lake Disappointment further to the South near the bottom edge.

Tan sediments from the Fitzroy River fill King Sound, about 120 km long and with an average width of about 50 km, on the northern coastline of Western Australia. These sediments slowly spread out of the sound and into the Indian Ocean, giving the waters a greenish hue.

Moving down the coast to the southwest, the shoreline takes on a whitish glow. This is due to the white sands of beaches such as Eighty Mile Beach. Also appearing white in color, further inland, are the Rudall River, connected to Lake Dora, with Lake Disappointment to the South. Both lakes are saline, as one might suppose from their white color.
