The longitudinal variations of water quality along the mainstream of the Nakdong River from May 1994 to October was surveyed by the measurement of chlorophyll a, total phosphorus, total nitrogen, dissolved inorganic phosphorus, nitrate-nitrogen, ammonia-nitrogen concentration, and secchi disc transparancy. Chl. a, TP, TN, DIP, NO_3-N and NH_3-N concentration was maintained at high level during the investigation period. And they also showed the peak after the input of Kumho River. Chl. a concentration increased from 14.2mg/m^3 in May to 95.2 in October. TP and TN concentration was maintained always above 100mg/m^3 and 3∼4mgN/l, respectively. TN/TP ratio were less than 16 from June to September with a few exceptions. Therefore, nitrogen is the limiting nutrient in the Nakdong River. Trophic states were in the range of eutrophic to hypertrophic, from 60 to 80.
