Poyang Lake is the largest freshwater lake in China. Dongting Lake is the second largest, stretching between Hunan and Hubei provinces.
The water level of Dongting Lake dropped for over 40 days in a row and fell below the dry water level of 26.8 yards, and entered the dry season 4 months early due to the decrease in water from the upper stream of the Yangtze River coupled iwth the persistent high temperatures and low rainfall. On Aug. 13, the water level of Dongting Lake Chengling Rock Station was 26.2 yards, the lowest level for the same period in the past 30 years. Some of the tributaries and trunk canals in the northern part of Dongting Lake have dried up and stopped flowing.

This was also the earliest the dry season started since 1951. Multiple large areas of the lakebed are exposed in Poyang Lake, and many lakebeds have become "grasslands."
According to the Wuhan Flood Control and Drought Relief Command Office, as of 6 p.m. on Aug. 13, the water level at Hankou Station of the Yangtze River was 19.2 yards, and the current water level in the Wuhan section of the Yangtze River is the lowest in history for the same period since the hydrological records have been kept.
