This study was carried out to forecast the chloride concentration and to investigate the water quality for industrial water supply after closing the sluice gate in Keum river estuary reservoir. Chloride concentration was dilluted by input flow, depended on outside chlorine mass than inside mass form reservoir body. The forecasting equation for chloride concentration is got Ci=3700·e ?? + 405/ ?? +2.5 without considering input chloride concentration from upstream river. The water quality in intake station for industrial water supply was satisfied for the standard for industrial water supply, but requried the physico-chemical treatment owing to maximum values of turbidity, pH, TS, Fe, Mn were exceed the standard.

The heavy metal contents of freshwater fishes in the Keum river were investigated during from March 1985 to February 1986. The contents of cadmium, chromium, copper, manganese and zinc in muscle and bone of several species of fishes were analysed. The heavy metal contents of the freshwater fishes collected at Dae-Dong Ri and Bu-yeo were comparatively higher than those of the Dae-Chong lake. The heavy metal contents in fish muscles were analysed as Cd 0.004∼0.028㎍/g, Pb 0.157∼0.937㎍/g, Cr 0.039∼0.235㎍/g, Cu 0.278∼1.472㎍/g, Mn 0.252∼1.189㎍/g and Zn 3.199∼12.772㎍/g, and in fish bones as Cd 0.250∼0.158㎍/g, Pb 1.173∼5.050㎍/g, Cr 0.769∼2.711㎍/g, Cu 1.275∼2.429㎍/g, Mn 2.917∼21.032㎍/g and Zn 29.052∼45.348㎍/g. The heavy metal contents in bones were significantly higher than those of muscles in almost all kinds of fishes. And accumulation of heavy metals in tissues of fishes tended to increase with the body weight .The heavy metal contents of fishes in the Keum river were lower than the limit contents of the heavy metis in food permitted by FAO.
