    In general, the growth curve is divided into four stages such as a lag phase, a log phase, a stationary or death phase. The algae needs several different nutrients at each phase. In this study, I tried to analyze a correlation divided on algae growth stages between a algal growth and water quality factors in lake Daechung. On the result of analysis, there was a normal correlation between Chl-a and several factors affiliated with nitrogen on the lag phase. On the log phase, strong correlations began to show between Chl-a, the number of cyanobacteria and water quality factors affiliated with phosphorus element. And the number of cyanobacteria also began to relate high to the number of total algae. During an entire period, there was a significant correlation between Chl-a and COD, so COD had a possibility to be a major nutrient for a algal growth. To control a algal growth for lake Daechung, I recommend to make the basic plan of water quality management included T-N control method for the spring, strong T-P control way for the summer and COD control plan for the entire period.
