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.

The often dry Lake Mackay, the largest of hundreds of ephemeral salt lakes scattered throughout Western Australia and the Northern Territory, shows the presence of water in this image, taken after Tropical Cyclone Rusty (17S) drenched the region. The popcorn clouds dotting the skies around the lake are also an indication of rapid plant growth after rainfall in an arid area.

Australia – March 7th, 2013

Lake Mackay is the largest of hundreds of ephemeral salt lakes scattered throughout Western Australia and the Northern Territory. The lake measures approximately 60 miles (100 kilometres) east-west and north-south. However, the lake is often rather dry and white in appearance due to its salinity and salt flats left behind after evaporation.

Here, however, heavy rains due to Tropical Cyclone Rusty (17S) have caused a greater influx of water into the lake. The darker areas indicate desert vegetation or algae present in moist areas. The brown patches are hills scattered across the eastern half of the lake and east-west-oriented sand ridges south of the lake.

Australia – January 10th, 2013

Fires can be seen south of Lake Mackay in this image of the border area of Western Australia and the southern part of the Northern Territory. Another fire can be seen to the east in the full image.

The lake (top left) is the largest of hundreds of ephemeral salt lakes scattered throughout the two regions. This image documents the appearance of the dry parts of Western Australia’s Great Sandy Desert, Gibson Desert and Tanami Desert.

The Northern Territory has had a sweltering start to 2013, with many places setting new temperature records. The high temperatures and dryness of the region create prime conditions for fires.

Australia - March 31st, 2011

Lake Mackay is the largest of hundreds of ephemeral salt lakes scattered throughout Western Australia and the Northern Territory. The lake is often dry and appears as a white salt flat.

However, in this image, water appears to be present, with several greenish channels visible throughout the lake, and greyish green coloring from water, algae or some sort of desert vegetation in the western half.
