The history of Hongjiannao to 1969 in the water area of 67 square kilometers, is relictus breeding and habitat and the world’s largest desert freshwater lake in China’s largest, known as the "Pearl of the desert". In recent years, Hongjiannao is facing a serious crisis of survival, the upstream surface recharge river is dam interception, the lower lakes were developed into tourist attractions.

Since the beginning of 2006, Inner Mongolia, Yijinhuoluo, respectively, on the two rivers dam interception. Has not been added to the lake area. Because the annual evaporation of Hongjiannao area is 2000 mm, annual rainfall probably between 350 to 400 mm. 1600 mm evaporation and rainfall is mainly dependent on the supply of rivers.
