| Data were collected in Lake Daecheong from March 1997 to October 2002 and used to understand an annual change of water environmental factors and trophic states. The surface water temperature was ranged from $3.2^{circ}C;to;33.1^{circ}C$. In the middle of February, water temperature was the lowest. Turbidity was ranged from 0.1 to 203.5 NTU, but the values of above 30 NTU were only measured at site 1. The total mean values of COD and Chl ${alpha}$ were $3.6{pm}1.4mg;O_2L^{-1},;9.3{pm}12.8{mu}g;L^{-1}$ respectively. The concentrations of TP and TN were ranged from 0.14 to 5.09mg $NL^{-1}$, 1 to $247{mu}g;PL^{-1}$ respectively. The total mean value of TN/TP ratio was $98.7{pm}56.2$. The trophic states were ranged from mesotrophic to eutrophic in Lake Daecheong. |
