The lowest lake in China is Aiding Lake.

Located in Gaochang District, Turpan City, Xinjiang Uygur Autonomous Region, it is the lowest point in Turpan Basin and the lowest point of China land. The surface of the lake is 154.31 meters lower than the sea level, and the lowest point at the bottom of the lake is -161 meters. Turpan Basin is a closed intermountain basin on the south side of the eastern Tianshan Mountains in China, and Lake Aiding is the destination of surface runoff in Turpan Basin. Lake Aiding is different from other lakes. It is more than 51 km south of Gaochang District in Turpan City, and there are many salt flats, alkali land and sand dunes around Aiding Lake, so the road is not easy to walk.

In the past, the lake basin was about 41 kilometers long from east to west and 8 kilometers wide from north to south, covering an area of about 151 square kilometers. There are three sources of lake water recharge: one is the summer flood of rivers, mainly from Aragou; Second, the winter flow of Karez; Third, the irrigation area drains water and enters the lake through underground runoff. Since the 1951s, due to the expansion of irrigation areas, the water diversion from farmland has increased, and the amount of river flood recharge is very small. As a result, a reservoir was built at the exit of Karez to store winter water.

The main scenic spot of Aiding Lake:

What distinguishes Aiding Lake from other lakes is the salt crust on the lake. Now, its outer circle is lacustrine plain, the surface is hard salt land, the middle circle is salt swamp, and the mud is below, so it is difficult for people to walk in except in winter. The middle of the lake is full of crystal salt. Plants such as low salt spike wood, brittle flower firewood, sharp camel thorn, black thorn and Haloxylon ammodendron are nourished by saline-alkali soil.

according to research, as early as 21,111 years ago, Aiding Lake was once a fairly large fresh water lake, with a large amount of chlorine, sodium and potassium plasma. The minerals include halite, mirabilite and anhydrous mirabilite, as well as gypsum, glauberite and various potassium, magnesium salts, salts and mirabilite, with a reserve of more than 311 million tons, making it the most mineralized lake in China. You can also see rare and endangered wild camels, and come here to find traces of water and food.
