The samples of macrobentic fauna from the three station was determined each month via kink-net. From the research area, 28 taxa were found belong to Amphipoda, Diptera, Lumbriculida, Hemiptera, Odonata, Emphemeroptera, Coleoptera, Gastropoda, Hirudinida, Trichoptera, Plecoptera ,Isopoda and Planaria. The percentage of the determined organizms as follows: 31.62% Diptera, 30.43% Amphipoda, 8.82% Trichoptera, 7.46% Lumbriculida, 5.93% Gastropoda, 4.32% Odonata, 4.03% Ephemeroptera, 3.34% Hemiptera, 1.73% Coleptera, 1.03% Hirudinida and 1.32% unidentif macroinvertebrata. The most organism groups compared with the stations are as follows: in the first station Gammarus sp., in the second station Similuim sp., in the third station Ablabesmiya sp. The most dominant organism groups were Gammarus sp. (37%) and Hydropschye sp. (22%). In the research area, in the spring, Gammarus sp. and Simulium sp.
