Poyang Lake

Poyang Lake is China’s largest freshwater lake, in Jiangxi Province. Its area changes sharply with the seasons as water levels respond to rainfall and exchange with the Yangtze River.

Yangtze River: The Yangtze is Asia’s longest river, flowing across China to the East China Sea. The river receives water from Poyang Lake and can slow or reverse its outflow.
Poyang Lake National Nature Reserve: Poyang Lake National Nature Reserve is a protected wetland area in Jiangxi Province, established to conserve wildlife and habitat. It protects key wintering grounds within the lake’s wetland system.
Poyang Lake drought: Poyang Lake drought is an episode of unusually low water that exposes extensive lakebed and stresses wetland ecosystems. Extreme low-water events reveal how far the lake can contract.
Poyang Lake Water Conservancy Project debate: The Poyang Lake Water Conservancy Project debate concerns whether regulating lake levels with sluices would justify ecological and hydrological costs. Its central dispute is whether water security can improve without damaging seasonal habitats.
Gan River: The Gan River is a major river in Jiangxi Province and a tributary of Poyang Lake. It supplies much of the lake’s inflowing water from the south.
Siberian crane: The Siberian crane is a critically endangered migratory bird that breeds in Russia and winters mainly in China. A large share of its population winters in Poyang Lake’s shallow wetlands.
Poyang Lake flood: A Poyang Lake flood is an episode of unusually high water that inundates surrounding wetlands and settlements. Floods demonstrate the lake’s capacity to expand beyond its dry-season footprint.
Three Gorges Dam: The Three Gorges Dam is a large hydroelectric dam on the Yangtze River in Hubei Province, China. Its reservoir operations are among the human influences studied in relation to downstream lake levels.
Lake–river interaction: Lake–river interaction is the exchange of water, sediment, and organisms between a lake and a connected river. The Yangtze’s changing levels govern the lake’s drainage and seasonal extent.
East Asian–Australasian Flyway: The East Asian–Australasian Flyway is a migration route connecting breeding and nonbreeding grounds across eastern Asia and Australasia. Poyang Lake is a major stopover and wintering area along this route.
