Agriculture reservoirs need a systematic approach that can control water purity and water improvement. The area under study, Bunam Lake exceeds the agricultural water standard level due to contamination from the upper stream. When the Taean Enterprise City was planned, the water quality improvement plan was applied to minimize the environmental change. However, in order to continuously maintain the water quality in the Bunam Lake, it was essential to apply the Total Pollution Load Management System (TPLMs). In order to achieve the targeted water quality in the Bunam Lake, standard flow rates and targeted water quality levels were applied to obtain the loading capacity which is as follows : BOD 1,891.2 ㎏/d, T-N 1,945.7 ㎏/d, T-P 131.7 ㎏/d. Also, the regional development load was calculated as, BOD 1,083.6 ㎏/d, T-N 942.2 ㎏/d, T-P 61.8 ㎏/d, which is required to be deceased :- by BOD 378.4 ㎏/d, T-N 198.9 ㎏/d, T-P 31.6 ㎏/d in order to safely achieve the targeted water quality in the Bunam Lake.
