Phytoplankton and environmental factors were investigated at Odae cheon from 20 July to 21 July, 1981. Seventy four species of phytoplanktons were identified. Of these, nine species which were all epiphytic and small in size were shown at all stations. The presence of Synedra ulna var. ramesi, Ceratoneis arcus var. amphioxys and Gomphonema constrictum var. capitata was a unique phenomenon in this studied area. Water body going down to lower stream, species number of phytoplankton increased except for the lowest station, station 6 and pH value increased gradually. But diatoms were found in abundance at all stations.
