Yeongju Dam has been constructed with the purpose of water supply for downstream. However, the watershed is abundant in agricultural and livestock activities, posing a high potential for acting as a source of nutrient pollution. Sediments may act as a reservoir for pollutants entering from upstream, and when environmental change occurs, stored pollutants may be released, further acting as a source of contamination. It is meaningful to observe the changes in contamination levels of sediments after the construction of Yeongju Dam. Sediment samples were collected from Yeongju Dam over the past three years and their characteristics, heavy metal contamination, and nutrient pollution levels were analyzed. Sediments in Yeongju Dam, located in Naeseong stream, showed relatively low levels of heavy metal contamination. However, over time, there was a slight increase in the concentrations of arsenic and mercury. The sediment"s composition revealed an abundance of initial sandy particles with predominantly large particle sizes, suggesting that these sediments are likely remnants from the riverbed existing at the time of dam construction. An increase in fine particles was observed over time due to sedimentation. The nutrient pollution levels increased over time, indicating upstream pollution flow in. In elution tests of the sediment, higher phosphorus release was observed under anaerobic conditions compared to aerobic conditions.
