The epilithic diatom assemblage and the assessment for water quality of the Naktong River using Diatom Assemblage Index to organic water pollution (DAIpo) are discussed. The diatom samples were collected from seven different stations at four times; April, August, October and December in 1995. In this study 194 diatom taxa were identified, which are classified into 163 species, 1 forma and 30 varieties belonging to 39 genera, 10 families, 3 suborders and 2 orders. Eight of these taxa were first reported from the river in the study. In the middle and upper reaches from st 1 to st. 3, Achnanthes minutissima classified into the indifferent species group to organic water pollution and Achnanthes convergens, saproxenous species group, were mainly dominated. However Nitzschia palea and Navicula goeppertiana, saprophilous species group, were dominant taxa in the lower reaches from st. 4 to st. 7. DAIpo values decreased rapidly below 38.81 of the average value in the four sampling times as going to the lower reaches from st. 4, however, the variation of them was independant of the changes of the sampling times.
