Poyang Lake

鄱阳湖 (Póyáng Hú)

China's largest freshwater lake, a sea in summer and a grassland in winter

Poyang Lake in northern Jiangxi is the largest freshwater lake in China, draining into the Yangtze at Hukou. Its area swings dramatically with the seasons, from several thousand square kilometres in the summer flood to scattered channels and pools in winter, and those exposed mudflats and meadows host almost the entire world population of the Siberian crane. The core of the lake is a national nature reserve and one of China's first Ramsar sites.

Overview

Poyang collects the water of five rivers — the Gan, Fu, Xin, Rao and Xiu — which together drain almost all of Jiangxi, and releases it into the Yangtze through a narrow neck at Hukou, beneath Mount Lu. In the rainy season, when the Yangtze runs high, water backs up into the lake, which spreads across a vast basin. In the dry season the level falls by ten metres or more, and the lake shrinks to river channels and a mosaic of shallow pools, sedge meadows and mudflats.

This rhythm makes Poyang one of the most important wetlands in Asia. From October to March it is the wintering ground of hundreds of thousands of waterbirds, including nearly all the world's Siberian cranes, and it is also a refuge for the Yangtze finless porpoise.

How the landscape formed

The lake occupies a subsiding basin south of the Yangtze, bounded by faults, into which the Jiangxi rivers have built deltas. Its shape is roughly an hourglass: a narrow northern arm leading to the Yangtze and a broad southern basin dotted with islands and deltas. Because the bed is so flat, a small change in water level exposes or floods great areas. Recent decades have seen more frequent and severe low-water periods, attributed to drought, reduced Yangtze flows and sand dredging, which have raised concern for the wetland's future.

Highlights

  • Wucheng

    吴城 (Wúchéng)

    An old river-port town at the heart of the nature reserve, the main base for watching wintering cranes and geese.

  • Dahu Pool

    大湖池 (Dàhú Chí)

    One of the seasonal lakes of the reserve where cranes gather to feed in winter.

  • Stone Bell Mountain

    石钟山 (Shízhōng Shān)

    A rocky hill at Hukou where the lake meets the Yangtze, famous for Su Shi's essay on the booming sound of waves in its caves.

  • Fallen Star Islet

    落星墩 (Luòxīng Dūn)

    A tiny island with a pavilion that stands in water in summer and on dry land in winter.

  • Shoe Island

    鞋山 (Xié Shān)

    A rocky island in the northern lake shaped like an upturned shoe.

Plants and wildlife

The winter wetland supports one of the largest concentrations of waterbirds in East Asia: cranes, storks, spoonbills, swans and hundreds of thousands of geese and ducks. The sedge meadows and submerged plant beds that feed them depend on the natural rise and fall of the lake. A ten-year fishing ban on the Yangtze and its main lakes, in force since 2021, covers Poyang and aims to restore fish stocks and the porpoise population.

Plants

  • Sedge meadows

    苔草 (táicǎo)

    Carex meadows cover the exposed lake bed in winter and feed geese.

  • Eelgrass

    苦草 (kǔcǎo)

    Vallisneria beds whose tubers are the main winter food of Siberian cranes.

Wildlife

  • Siberian crane

    白鹤 (báihè)

    A critically endangered crane; almost the whole world population winters in the Poyang basin.

  • Oriental stork

    东方白鹳 (dōngfāng báiguàn)

    An endangered stork that winters on the lake in large numbers.

  • Yangtze finless porpoise

    长江江豚 (Cháng Jiāng jiāngtún)

    A critically endangered freshwater porpoise; the lake holds a large share of the remaining population.

  • Swan goose

    鸿雁 (hóngyàn)

    A vulnerable goose whose main wintering area is the middle Yangtze lakes.

Culture and legend

The lake has been a highway and a battlefield. In 1363 Zhu Yuanzhang, future founder of the Ming dynasty, defeated his rival Chen Youliang in one of the largest naval battles in history on its waters. Jingdezhen porcelain travelled down the Chang River and across the lake to the Yangtze. Su Shi's essay “Record of Stone Bell Mountain” (1084), in which he tests earlier explanations of the mountain's name by visiting it at night, is a classic of Chinese prose.

  • Laoye Temple

    老爷庙 (Lǎoyé Miào)

    A lakeside temple on a stretch of water notorious among boatmen for sudden storms and shipwrecks.

  • Battle of Lake Poyang

    鄱阳湖之战 (Póyáng Hú zhī zhàn)

    The naval battle of 1363 that decided the contest for southern China before the founding of the Ming.

Through the seasons

  • Spring

    Water rises as the rains begin; the birds leave in March and the meadows flood.

  • Summer

    The lake at its fullest, a sea of water with islands; the flood season can bring serious flooding around its shores.

  • Autumn

    Water falls from September; the first cranes and geese arrive in October.

  • Winter

    The birdwatching season, from November to February, when the lake bed is exposed and the pools fill with cranes.

Routes and ways in

  1. Wucheng and the reserve

    From Wucheng town, walks and boat trips reach the seasonal pools and observation towers of the national nature reserve.

  2. Eastern shore wetlands

    Wetland parks on the eastern and southern shores near Poyang county and Nanchang have observation hides for cranes.

  3. Hukou and Stone Bell Mountain

    The meeting point of the lake and the Yangtze, near Jiujiang.

Practical notes

  • Birdwatching depends on water levels, which vary greatly from year to year; local reserve staff know where the birds are.
  • Winters are damp and cold with wind across the flats; warm, windproof clothing is essential.
  • Core zones of the reserve are closed; observe birds from towers and hides without approaching flocks.
