Total phosphorus (TP) and suspended solids (SS) were measured in the discharge waters from 5 drainage basins of Lake Yongdam, from April, 2002 till March, 2004. The responses of SS and TP to rainfall were analyzed and their loadings into Lake Yongdam were calculated. The inflowing rivers into Lake Yongdam were the Juja River, the Jeongja River, the Jinan River, the Geum River and the Guryang River. Among these rivers Sinan River showed the highest TP that fluctuated very much according to the flow rate. TP and the flow rates (Q) of each river showed positive correlations with empirical relationship of $TP=6.32Q^{0.30}$ for the Juja River, $TP=8.58Q^{0.49}$ for the Jeongja River, $TP=307.92Q^{0.10}$, for the Sinan River, $TP=17.91Q^{0.47}$, for the Geum River, $TP=20.11Q^{0.53}$, for Guryang River. In April $2002{sim}March$ 2003, phosphorus loadings from the Juja River, the Jeongja River, the finan River, the Geum River and the Guryang River were calculated to be 3,677, 11,430, 36,412, 89,651, and $42,226kgP{cdot}yr^{-1}$ respectively. And the specific loadings from the Juja River, the Jeongja River, the Jinan River, the Geum River and the Guryang River were calculated to be 0.3, 2.9, 13.0, 9.3, and $13.0kgP{cdot}km^{-2}{cdot}yr^{-1}$ respectively. In April $2002{sim}March$ 2004, the suspended particles loading from the Juja River, the Jeongja River, the Jinan River, the Geum River and the Guryang River were 073, 1,232, 4,232, 36,902, $80,202;ton{cdot}yr^{-1}$ respectively. The Guryang River showed the largest contribution of SS loading.
