There is Lake Eyre in central Australia. In 1832, an exploration team discovered that there was a basin with a thick layer of salt. In 1860, another expedition discovered that it had become a Great Salt Lake. The next year, when the expedition team came here again, they found that the lake had mysteriously disappeared. It is said that this is a seasonal lake that disappears periodically every three years.
There is also Lake George in Australia, located between Canberra and Sydney. From 1820 to the present, the lake strangely disappeared five times and reappeared five times, with the last disappearance occurring in 1983.
There is also a lake like this that disappears and appears in Yangshuo County, Guangxi, my country, called Rhinoceros Lake. On September 30, 1988, the clear water of Rhinoceros Lake disappeared without a trace overnight. According to local county records, this lake disappearance occurs approximately every 30 years.
Scientists have studied the phenomenon of lake water periodically disappearing for many years. Some people believe that the water sources of these seasonal lakes are mainly river water and rainwater. If there is little rainfall that year and a large amount of water evaporates, they will dry up and therefore appear and disappear.
