Lake Nányī

Lake Nanyi lies in the low country east of Xuancheng in southern Anhui. It is one of a chain of lakes formed as the ancient Danyang marsh gradually filled with silt and separated into smaller bodies of water. The Langchuan River enters from the northeast, and the lake drains westward toward the Shuiyang River and the Yangtze. Its broad, shallow waters collect runoff from the surrounding hills and spread across the plain when rains swell the rivers.
