Abstract—To evaluate the impacts of wastewater from upper fresh water lake in North China Plain. There are 146 lakes in reaches, characteristics of munity were large or small sizes; these lakes are linked together by more investigated using (PFU) method at four sampling stations in than 3,700 ditches and river courses. Among them the Baiyangdian Lake. At the same time, water sampling from these Baiyangdian is the largest one. Thus the name of the lake stations was conducted and five chemical parameters, including + comes into being. Baiyangdian Lake plays an important role TP, TN, CODcr, NH4 -N and BOD5, were analyzed. not only in mercial fishing, but also for Comprehensive chemical pollution index (PB) was also calculated navigation, tourism and recreation as well as being of great based on the five chemical parameters. A total of 172 protozoan conservation value in its wild life and wetland system. Since species were indentified, including 44 species of the 1970s, Baiyangdian Lakes subjected to serious pollution Phytomastigophoreas, 17 species of Zoomastigophoras,
