Taihu Lake water system shows a trend of discharge from west to east, with an average annual runoff of 7.5 billion cubic meters and a storage capacity of 4.4 billion cubic meters. Taihu Lake has more than 50 islands, of which 18 are inhabited.

Changes in the territory of Taihu Lake

Before the Spring and Autumn Period and the Warring States Period, Taihu Lake was originally an alluvial plain on land. In the Tang Dynasty, the lake reached the bank of Wujiang pond. Dongshan and Xishan in Dongting were originally two big islands in the lake. Later, due to sediment deposition between Dongshan and Mudu, the beach expanded. By the middle of Qing dynasty, the islands were connected by sandbars, making East Taihu Lake a big bay of Taihu Lake.

In recent 1200 years, due to the intensification of siltation on the east and northwest coasts of East Taihu Lake and the reclamation of the lake beach, East Taihu Lake has actually become a long and narrow shallow dry lake area with serious water resistance. The changes of modern Taihu Lake are most prominent in the East Taihu Lake area.

In 1960s and 1970s, the area of Taihu Lake and its surrounding lakes decreased by 13.6% due to reclamation around the lake, and 165 lakes disappeared or basically disappeared, with a total area of 16 1 km2. Among them, Taihu Lake and crossing the lake are the most prominent, and Ma Jishan Island in the northwest of Taihu Lake is connected with the land because of reclaiming land from the lake. Due to the acceleration of the speed of encircling the lake in the north, east and south directions of the lake, the original lake surface has been greatly reduced.
