This study was investigated to an assessment of water quality by attached diatoms at 7 stations in the Pochun stream from April, 1998 to Febuary, 1999. Total 105 taxa were identified, which were composed of 93 species, 10 varieties, 1 forma and 1 unidentified species, belong to 2 orders, 3 suborders, 8 families and 20 genera. Navicula subminuscula, Nitzschia palea, Navicula minima and Gomphonema pseudoaugur classified into saprophilous group to organic pollution, were dominated at station 1, 2, 3, 4, and 5 in the main stream. However Gomphonema parvulum, saproxenous group and Achnanthes lanceolata, Cocconeis placentula and Nitzschia fonticola, indifferent group, were dominated at station a and b. The DAIpo was ranged from 46.5 (St. b) to 11.6 (St. 2) of the average value in the six sampling times. The water qualities by DAIpo of Pochun stream were estimated from ${eta}$-mesosaprobic to polysaprobic states.
