补充资料：沂河
| 沂河 位于中国山东省南部和江苏省北部。源出山东省沂蒙山区的沂源县鲁山 。 南流过郯城县进入苏北平原。沂河原来是在今睢宁县北境古邳镇（古称下邳）汇入泗河，是泗河主要支流。1128～1855年黄河南徙夺泗水和淮河干流入海。由于河床淤高，1855年黄河北徙后，沂河失去了入泗入淮的流路，除潴水为骆马湖外，还经常泛滥于废黄河以北、骆马湖以东广大地区，过去内涝灾害严重。中华人民共和国建立后，经过对沂河的整治，沂河自山东流入江苏后，除部分来水经华沂闸（在邳州市和新沂市界上）西南流经窑湾入中运河外，主要来水自华沂闸经新辟的新沂河南流入骆马湖，再经沭阳直达燕尾港，由灌河口入海。全长约574千米。 |
