In order to the epilithic diatom community and an assessment of water quality with diatom assemblage index of organic water pollution (DAlpo) in the middle reaches of the Nakdong River, the samples were collected from nine sampling stations on May, July, September, November, 2002 and on January 2003. A total 162 taxa was identified from this study, which were classified into 139 species and 23 varieties belonging to 33 genera. Achnanthes minutissima, Navicula subminuscula, Navicula viridula var. rostellata, Nitzschia inconspicua and Nitzschia palea indentified in every stations and examination for the whole periods. A total of 12 taxa was dominant species at any station at least one more times. In this study, average DAlpo was 30.90 ${sim}$ 44.61 and the saprobic level was estimated ${eta}$-mesosaprobic in the middle reaches of the Nakdong River.
