| The biological and physicochemical factors and geosmin concentration were monitored in the Daechung Reservoir for 25 weeks from April to October in 1999. Geosmin was detected 5 times within a range of $1.16{sim}5.28;ng;L^{-1}$, mostly in the late summer. The highest geosmin concentration was recorded on August 31, which also overlapped with the peaks of phycocyanin concentration, cyanobacterial density, and Anabaena spiroides density. A correlation analysis indicated that geosmin production was closely related with a high water temperature, pH, total dissolved phosphorus (TDP), and A. spiroides density. A water temperature of $27^{circ}^C$, pH of 8.5, and TDP of $0.06;mg;L^{-1}$ were identified as the prerequisite environmental condition sand threshold values for geosmin production. Accordingly, under such conditions, an A. spiroides density above $10,000;cells;mL^{-1}$ indicates imminent geosmin occurrence. |
