Freshwater lakes cover an area of 36,000 square kilometers. The Middle-Lower Changjiang (Yangtze River) region has the most lakes because it has plenty of rainfall and a low, gentle terrain. The five largest freshwater lakes are, in order of their size: Poyang in northern Jiangxi, Dongting in northern Hunan, Hongze in western Jiangsu, Taihu in southern Jiangsu, and Chaohu in central Anhui. Hongze Lake is situated in the Huang-Huai Plain and the four others are all in the Middle-Lower Changjiang (Yangtze River) Plain. Hebei, known as the “ province of one thousand lakes”, leads china’s provinces in number of lakes. Most of the lakes in the Yunnan-Guizhou Plateau are fault lakes, the best-known being Dianchi in eastern Yunnan and Erhai in western Yunnan. There are a number of freshwater lakes in the North China and Northeast plains and sizable ones in Xinjiang and the Qinghai-Tibet Plateau.
