Cluster analysis was applied for the distinction of the water body in Soyang lake, whcih is the largest lake in Korea. For this analysis, the sixteen environmental parameters, such as water temperature, nutrient salts, organic materials, etc were used as the input data. The total data matrix was 16 parameters X 47 points (in 14 sites). After Standardization, the Euclidean distances between two points were calculate. By the results, main stream of Soyang lake can be classified with 5 groups in March, 10 groups in February. And two shallow tributaries, showed different grouping pattern from main stream. In March, and November, the vertical mixing was detected, and in August, the water body above 10 m was showed complex grouping pattern, and showed two water bodies in middle layer, and one in bottom layer.
