This study was conducted to assess water quality of Dae stream in Busan using the periphyton. Species of the higher rank 10% in standing crops were Cymbella ventricosa, Aulacoseira granulata, Gomphonema olivaceum, Synedra ulna through the study. In addition, Fragilaria intermedia ill the station 1 and 2, and Nitzschia palea in the station 3 and 4 dominated the periphyton community respectively. These species mainly appeared in the urban stream. Where input of pollutant is forecasted, standing crops of dominant species are investigated very highly. Also, standing crops of Nitzschia palea were higher in the pollution area such as polysaprobic than any other area. Water quality by the saprobic index were oligosaprobic in the station 1, $eta$-mesosaprobic in the station 2 and 3, and $alpha$- mesosaprobic in the station 4. These results suggests that the pollution of Dae stream gradually increased with downstream due perhaps to the loading of sewage from the new residental complex.
