Wangsong Reservoir needs a systematic approach that can control water purity and water quality improvement. This study was carried out to assess the seasonal variation of water quality and the effect of pollutant being loaded from watershed in a sallow eutrophic reservoir(Wangsong Reservoir) from March to November, 2011. Wangsong Reservoir, located in Uiwang City, has the capacity of 2 million $m^{3}$ in irrigation water supply with the drainage of 4.2 $km^{2}$. Average concentrations of BOD, COD, T-N, T-P, and Chloropyll-a in Wangsong Reservoir were 5.8 mg/L, 9.7 mg/L, 4.299 mg/L, 0.106 mg/L and 73.1 mg/$m^{3}$, respectively. In the inflow streams and treated sewage of Wangsong Reservoir, the T-N concentrations of 4.114 - 14.619 mg/L were higher than those in the Reservoir and the other pollutants were lower. As a result of investigation, Wangsong Reservoir exceeded the agricultural water standard level due to algal growth and accumulation from the upper streams and sewage. In order to achieve the targeted water quality in Wangsong Reservoir, it is required to be decreased in pollutants of internal and inflow streams.
