This study was performed to determine Oligochaeta fauna and some physicochemical features of Corlu Stream which is the large part of Meric-Ergene River Basin. A total of 9 Oligochaeta species belonging to Tubificidae (4 species) and Naididae (5 species) was recorded in the study during seasonal sampling carried out between 1990 and 1991. Furthermore, some physicochemical parameteres (pH, conductivity, dissolved oxygen, biological and chemical oxygen demands) in the stream which was under the pressure of intensive pollution because of urban and industrial wastes, were measured. To determine the changes in species composition and pollution level one more sampling was made in 2008. Also, some physicochemical features (pH, temperature, dissolved oxygen, nitrite, nitrate, sulphate, phosphate, H2S, Suspended Solid Matter) were measured beside Oligochaeta sampling. It was observed that number of total oligochaeta species was decreased to 4 and the quality of water in the stream was further deteriorated.
