The water quality criteria of the Yongdam basin is polluted over second grade. Trophic state in the area indicate supper eutrophic state. This study was conducted to analyze the distribution characteristics of the nutrient, and to find the interrelationships among them, focusing upon the eutrophication in the Yongdam dam basin.
The results of this study were as follows;
1. Nutrients was estimated as total nitrogen of 1.021∼1,034㎎/ℓ.
2. The trophic state was supper entrophic, and the state of DO level was supersaturation in spite of high organic loads from the each tributary.
3. The limiting factor of the reservoir is T-P, according to the criteria of eutrophication.
4. After Dam construction, T-P concentration of 26㎎/㎥ and Korea Trophic State Index of 50 were predicted.
