The yearly average water qualities of the Whang river, which flows into the Hapcheon lake, were COD , T-N and T-P during . The yearly average COD concentration of Hapcheon lake was increased from 1.9 mg/L (in 1996) to 2.7 mg/L (in 2000). However, T-N and T-P concentration of Hapcheon lake did not show increasing trend over the 6 year period During , the yearly average concentrations of T-N, T-P were , respectively. The correlation coefficients between chlorophyll and T-N, T-P, rainfall intensity, water temperature were 0.382, 0.372, 0.589, and 0.526, respectively. Therefore, the rainfall and water temperature appeared to play an important role far the variations of chlolophyll concentration in the Hapcheon lake. Trophic state of the Hapcheon lake were evaluated to be in the range of mesotrophic to eutrophic.
