[:ja]NASAの地球観測衛星Landsat 8が撮影したチリのアクレオ湖です。2018年5月9日に完全に干上がってしまったことで、有名になりました。画像は2019年3月12日のもので、緑色の部分は水ではなく植物です。
アクレオ湖は、湖岸は泥地で、明確な傾斜がないのが特徴です。かつての面積は12km2、水深は6m、サンティアゴ近郊の避暑地として人気がありました。近年、気候変動による干ばつの影響で、2011年から水位が下がり始め、また、灌漑用水として湖の水が乱用されたことも湖が干上がった原因とされています。
水が豊富にあった2009年に地上の様子はこちらです。
干上がった現在の様子はこちらです。

[Earthview Wonders] No.797: Lake Aculeo, Chile🇨🇱
NASA’s Landsat 8 satellite captured the dried-out Lake Aculeo (Laguna de Aculeo), Chile.
Laguna de Aculeo is as of 2018 a dried-out lake located in the city of Paine, Maipo Province, Santiago Metropolitan Region, Chile. It features muddy banks, because the surroundings are not steep. The average annual rainfall in the region dropped from 350 mm/y in the 1980s to less than half that in the 2010s. In 2011 the lagoon was 12km2 in size and 6m in depth. It disappeared entirely on May 9, 2018. Probable causes include a large influx of tourists, as well as using its waters for avocado cultivation.
The lake with abundant water in 2009 looked like this.
Dried-out lake looks like this today in 2019.
