Abstract This study was conducted to identify the physical features of reserved water so that low-temperature water in the deep part of dams can be used as a cooling energy source for buildings. Based on the relationship of horizontal distribution of water temperatures depending on the depth and external temperatures from 2001 to 2007 and topographical maps, monthly temperatures according to the depth and distribution phases of water turbidity were comparatively analyzed. As a result of the analysis, the body of water in the target lake of dam was divided into density layers according to the changes in water temperatures. Temperatures in the deep part of the dam remained at 4~10oC a year. The deep part of a cooler remained at the 10 m range (based on the minimum level) from the bottom of the dam with temperature of around 8oC. As a result of examining the horizontal distribution of density, the density around the surface of the dam varies according to the measured location. The density in the deep part was almost similarly low at 0.5 NTU. Distinguishing the amount of usable water is possible based on the ceiling temperatures of usable water and topographical maps.
