Variations of chlorophyll a in relation with freshwater quality in Korean reservoirs were in- vestigated during the period of 1992-2006. This study compared assessed total nitrogen (TN), total phosphorus (TP), total suspended solids (TSS), Secchi depth (SD) and phytoplankton bio­mass (Chlorophyll a (Chl)) relating to pre-mon­soon, monsoon and post-monsoon in South Korea reservoirs. Linear relationships were ob­served between log-transformed Chl and log- transformed TN, TP, TSS, SD and applied for all study sites to examine relationship of these fac­tors in South Korea reservoirs. The results demonstrated that phytoplankton biomass re­sponded to nitrogen and phosphorus enrichment and was also differently and remarkably related to TSS, SD in Korean reservoirs during pre-mon­soon, monsoon and post-monsoon.
