洪泽湖是我国五大淡水湖之一,面积2090平方公里,蓄水量31.5亿立米(相应水位12.5米),被人们称为“巨型平原水库”。历史上黄河多次夺淮,泥沙淤塞,湖底高出苏北里下河地区5～9米。这样,洪泽湖大堤就成了二千万人民生命财产和三千万亩农田的防洪屏障。大堤全长67.25公里,目前分三段管理,其中从蒋坝镇到洪泽县高涧船坞一段,相当于水库的正坝,长25.1公里,该段堤前水深浪大,为全堤防洪重点,亦是江苏省唯一的省管
Hongze Lake is one of the five largest freshwater lakes in China with an area of 2,090 square kilometers and a storage capacity of 3.15 billion cubic meters (corresponding to a water level of 12.5 meters), which is called “giant plain reservoir”. The history of the Yellow River repeatedly Huai Huai, sediment siltation, the lake bottom Lixia River in northern Jiangsu area 5 to 9 meters. In this way, the Hongzehu embankment has become the flood control barrier for the lives and property of 20 million people and the farmland of 30 million mu. Embankment length of 67.25 kilometers, is currently divided into three sections of management, which from Hong Kong Jiang dam town to a high section of the dock, equivalent to the reservoir Zhengba, 25.1 km long, deep water waves in front of the embankment for the whole flood focus , Is also the only province in Jiangsu Province
