Water colors

Xiechi Lake in Yuncheng, China, has such a high level of salinity, it's sometimes called China's Dead Sea. But unlike the Dead Sea in the Middle East, Xiechi Lake supports abundant microscopic life: algae and other microorganisms that have a high tolerance for the salt. In summer and autumn, the lake temperature is high enough to spark algae blooms, bringing a variety of intense colors to the lake water.
