Knowra Dongting Lake Dongting Lake Dongting Lake is a large freshwater lake in Hunan, China, connected to the Yangtze River. Its area changes sharply with seasonal river flows and rainfall.
Yangtze River : The longest river in Asia, flowing from the Tibetan Plateau to the East China Sea. Its floodwater and sediment enter Dongting Lake through connecting channels.
Dongting Lake wetlands : Wetland habitats around Dongting Lake, including marshes, mudflats, and seasonally flooded grasslands. They provide the ecological setting for the lake’s birds and fisheries.
Jingjiang : A section of the Yangtze River in Hubei and Hunan, historically prone to flooding and channel change. Its shifting channels helped shape the lake’s connection with the Yangtze.
Flood control in China : Policies and infrastructure used to reduce flood damage across China’s rivers and floodplains. Dongting’s storage capacity makes it part of broader Yangtze flood-control planning.
Three Gorges Dam : A hydroelectric dam and reservoir on the Yangtze River in Hubei, China. Its regulation of Yangtze flows affects water levels and sediment reaching the lake.
East Dongting Lake National Nature Reserve : A protected wetland area in Hunan established to conserve habitats and migratory waterbirds. It protects part of Dongting’s internationally significant wintering grounds.
Yangtze River flood of 1931 : A catastrophic flood in central China that killed hundreds of thousands of people and inundated vast areas. It shows the historical stakes of floods across the Dongting region.
Yangtze River Basin : The drainage basin of the Yangtze River, spanning much of central and eastern China. Changes around Dongting contribute to conditions across the larger basin.
Four Rivers of Hunan : The Xiang, Zi, Yuan, and Li rivers, which drain much of Hunan into Dongting Lake. These tributaries feed the lake from the south and west.
Siberian crane : A critically endangered migratory crane that breeds in Siberia and winters mainly in China. Dongting’s wetlands are among the important wintering habitats for this species.
