The largest lake that’s no longer a lake

There was once another lake that ranked among the world's largest bodies of water — just east of the massive Caspian Sea. Originally 26,300 square miles of water, the Aral Sea in Central Asia has shrunk to 10 percent of its original size. Since the 1960s, the lake’s waters have been diverted for irrigation — and now the once-vast lake has been split into smaller, separate lakes.
