The aim of this study is to allocate the amount of discharging pollution loads according to the main pollutants such as population, livestock, soil, industrial facilities of Yugu basin which is a branch of Geumriver. Also, the object area was divided into 22 small subbasin sectors to assess the loading amount and applicate the water quality model. The considering items to forecast the water quality were restricted BOD, TN and TP which had affluent data relatively. And only BOD data was used to calculate unit loading amount of the basin and arrangement of optimum pollution load. As a calculating result for the amount of discharged pollution load based on the pollution sources and data, the loading amount and density of the basin became the highest after joining of Yugu and Magok. And the results of the expected loading amount indicated the increase rate of load occurrence was less than average ±1.5% per year for BOD, TN and TP. So, it was known that factors such as population, livestock and industrial transformation kept up as present. The flow running rate for the small drainage sector by the running load amount was highly analyzed TP, BOD and TN in order. And the running load amount was high in case small basin and short running length. Also, BOD contribution rate was large as near the length for the end point of the stream and high pollution influx. The running load amount was 629.85kg/d and permission load amount was 483.03kg/d at the end of Yugu basin. Therefore, it is considered that the amount is to reduce 146.82kg/d and reduction load amount by the region on establishing the sewage treatment facilities was expected 185.07kg/d for Yugu, 22.21kg/d Shinpoong, 25.91kg/d Sagok, 20.26kg/d Woosung and 255.40kg/d after total same time reduction. So, it is concluded that the arrangement of optimum load amount for reduction is proper to Yugu, Sagok, Shinpoong and Woosung orderly.
