Abstract
Water quality parameters were surveyed in Lake Andong. Turbidity, temperature, secchi disc transparency (SD), phosphorus, nitrogen and chlorophyll a concentration were measured at dam site from July 1993 to December 1998. Minimum transparency in summer was only about 2 meters in 1993 and 1994, but it decreased to about 1 meter in 1997 and 1988. Total phosphorus concentration of the epilimnion increased slightly from
