This investigation was carried out in fresh water lake Koppa; it belongs to the largest lake of Bhadravathi taluk of Shimoga district. The one year analysis of physico-chemical characters of lake water revealed that Koppa is moderately polluted. Lake is mainly dependence on irrigation, domestic and aqua culture. A total of 23 physico-chemical parameters were analyzed; bicarbonates, total alkalinity, total hardness, chlorides, calcium, sodium and free carbon dioxide were comparatively high to potassium, phosphate, nitrates, nitrites and iron. The water have affordable levels of Dissolved oxygen (DO), PH, Conductivity, Total dissolved solids and Water temperature. The carbonates were shown nil throughout the sampling periods and biological oxygen demand (BOD) were less, it indicated that water body was so biologically not as much of polluted.
