This study was carried out to provide the basic informations for the water quality management in Boryung fresh water reservoir watershed. Four agricultural reservoirs were selected and the water qualify of the reservoirs were investigated from November 1998 to December 2000, periodically. Including storage rate, temporal variation of water quality constituents such as water temperature, pH, EC, total nitrogen, total phosphorus were analysed. The result showed that pH ranged 6.7~10.4, EC 56.1~1079μS/cm, COD 0.75~8.0mg/L, respectively. And, total-N concentration affected by the livestock wastes and agricultural activity ranged from 0.21 to 4.66mg/L and which was almost over the agricultural water quality standard(1.0mg/L). Total-P ranged from 0.001 to 0.080mg/L as lower than the agricultural water quality standard(0.1mg/L).
