Lake Hongze

Lake Hongze is located in Jiangsu Province, China and is encompassed by the cities Suqian and Huai'an. Lake Hongze is the fourth largest freshwater lake in China. Lake Hongze has become four times larger since the 1100s when the Yellow River changed its course. The heavy sendiment from Yellow River blocked the course of Huai River and diverted the water from Huai toward the lake.
