QUICK FACTS
The place is it? Barkly Tableland, Australia’s Northern Territory [-18.595019720, 135.2699610]
What’s within the picture? A sequence of ephemeral lakes which have merged right into a single physique of water
Which satellite tv for pc took the picture? Landsat 8
When was it taken? Oct. 30, 2024
This placing satellite tv for pc snap reveals a sequence of ghostly inexperienced lakes that merged right into a single murky entity after a number of years of bizarre climate within the Australian outback.
The entwined lakes are positioned in Barkly Tableland, an space inside Australia’s Northern Territory, which lies between the states of Queensland, South Australia and Western Australia. The biggest part of the conglomerate is Tarrabool Lake (on the left aspect of the picture), which stretches round 55 miles (90 kilometers) throughout at its widest level. It’s darkish inexperienced as a result of dense vegetation and algae within the water.
The smaller half of the merged lakes (on the suitable aspect of the picture) is made up of three lakes: Lake Sylvester, Lake Corella and Lake Deburgh. This part has a paler and chalkier hue attributable to excessive ranges of suspended sediment. That is probably as a result of the lakes have overflowed and combined collectively, whipping up the mud and topsoil that after surrounded them. (A number of different, smaller lakes of varied sizes and shades of inexperienced can be seen all through the picture.)
All of those lakes are ephemeral, which means they haven’t any fixed influx or outflow of water, very similar to most of Australia’s other lakes. Because of this, they virtually fully dry out throughout extended intervals of sunny climate, as excessive temperatures trigger the water inside them to evaporate, after which reappear as heavy rainfall refills the basins.
Nevertheless, throughout the 2 years previous to this picture, there was a lot rain that the lakes by no means dried out. As a substitute, they continued to develop 12 months over 12 months, as you’ll be able to see from further satellite tv for pc imagery (see beneath), which reveals the identical space between 2022 and 2024.
Further satellite tv for pc imagery reveals how the lakes grew considerably between 2022 and 2024. (These photos have been captured by the MODIS devices on NASA’s Aqua and Terra satellites.)

The Northern Territory’s wet season lasts between October and April. Each the 2022-2023 and 2023-2024 wet seasons, which preceded the 2024 satellite tv for pc images, have been ranked among the many high 10 wettest since 1990, in line with NASA’s Earth Observatory, which launched these photos.
Though that is excessive, it isn’t that stunning, contemplating that annual rainfall within the Barkly Tableland rose by round 14% between 1989 and 2018, in line with a report from the Australian Bureau of Meteorology. That is probably as a result of results of human-caused climate change.

On high of the overall improve in rainfall, Tropical Cyclone Megan dumped a large quantity of rain on the area in March 2024. The ensuing flash flooding was so nice that fish have been seen swimming throughout a close-by highway, Australia’s ABC News previously reported.
Within the winter, Tarrabool Lake and Lake Sylvester are essential breeding websites for birds, together with the straw-necked ibis (Threskiornis spinicollis) and the Australian pelican (Pelecanus conspicillatus), and BirdLife Worldwide lists each lakes as important bird areas. At its fullest, Tarrabool Lake additionally floods the encompassing Eva Downs Swamp system, creating Australia’s largest wooded swamp.
