Lakes Gregory and Mackay, Western Australia

20.2S 127.4E

March 27th, 2013 Category: Lakes

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.

Fires Near King Sound in Western Australia

August 2nd, 2012 Category: Fires, Lakes

Australia – August 1st, 2012

Several wildfires can be seen releasing plumes of smoke that blow in a generally westerly direction in this image of Western Australia. Fires can be seen southeast of Lake Argyle (image center) and northeast of King Sound, the sediment-filled body of water in the upper half of the image.

Fire on Coast of Western Australia

29.1S 119.5E

April 12th, 2011 Category: Fires, Lakes, Salt Flats

Australia - March 31st, 2011

Smoke from a fire near the coast of Western Australia blows offshore on the left side of this image. In the full image, the plume can be seen extending further out over the ocean and arching northward.

Also of interest are the whitish areas in the upper part of the image, evidence of the lakebeds of intermittent salt lakes. The largest of these is the “M-shaped” Lake Barlee, near the top edge.



Curves of the Rudall River in Western Australia

22S 122.9E

February 2nd, 2011 Category: Lakes, Rivers, Salt Flats

Australia - January 24th, 2011

The Rudall River snakes across this image of Western Australia and terminates in Lake Dora (by left edge). The white color in parts of the river is due to places with little water and high salt content that have become salt flats.

The Rudall is an ephemeral river but also a major watercourse with reliable water sources and many permanent pools. Lake Dora is also an ephemeral lake, filling with water when the Rudall River is carrying enough. In the full image, there appears to be some water by the center of the lake, although much of the rest of it appears as white salt flats.

Unusually Full Lake Macleod, Western Australia – January 13th, 2011

24.1S 113.7E

January 13th, 2011 Category: Image of the day, Lakes

Australia - December 26th, 2010

Lake Macleod is the westernmost lake in Western Australia. A cool, north-flowing offshore current from Antarctica that is not conducive to producing precipitation, coupled with a very flat coastal plain, contributes to the near-desert-like conditions along the coastal region as evidenced by the brown landscape around the lake.

The lake, in fact, often appears to be little more than a large white salt pan with little water, as was the case when it was previously observed by Eosnap (see here and here for previous articles). However, the lake is periodically inundated by freshwater, as in the case of this image from late December in which the lake appears bright green in color.
