永定河永定河海河流域五大水系之一。位于中国河北省西北部。上源有两支：南支为桑干河，发源于山西省宁武县管涔山，东流纳黄水河、浑河、御河等进入河北省境内再纳壶流河；北支洋河，源出内蒙古兴和县，于河北省境内张家口市纳清水河。原两支于河北省怀来县朱官屯汇流，汇流后始称永定河，自官厅水库建成后，两支均汇入官厅水库，官厅以下称永定河。经官厅山峡，至北京三家店出山，过卢沟桥以下形成地上河。向东流至屈家店与北运河（见京杭运河）汇合。全长681千米，流域面积5.1万平方千米（至屈家店）。上游流经黄土高原，河水含沙量仅次于黄河，故有小黄河、浑河之称。下游淤浅，河道迁徙无定，故又有无定河之称。清康熙三十七年（1698）为保护京城北京，筑永定大堤以固河槽，后定名永定河，但河水仍变化无常，经常决堤成灾。中华人民共和国建立后，在官厅以上先后兴建大、中、小型水库517座，总库容达33亿立方米。其中，以官厅水库的库容为最大，约22.7亿立方米。1970年开挖了永定新河，从屈家店到北塘，然后入渤海，以分泄汛期洪水，防止水害。
