Water and Vegetation in Lake Mackay, Australia22.5S 128.6E
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.
