Abstract: Sediment is the result of erosion process, either in the form of surface erosion, trench erosion, or other types of soil erosion. The increase of percentage of sediment in dam which increases rapidly each time, causing dam dredging and affecting dam capacity and service age of dam. This study discusses sedimentation sediment volume, sedimentation rate, sediment distribution, and estimated service age of Ponre-Ponre Dam in Bone, South Sulawesi. Sediment volume of sediments deposited at each elevation is marked by reduced dam volume. Sedimentation rate that occurs based on the sediment volume that stays every year. The service age of the dam is indicated by the reduction of the dam’s dead reservoir. The volume of sediments occurring at the Ponre-Ponre Dam in 2016 reached 8.7965437 X106m 3 . The rate sedimentation that occurred around 1.2566491 X106 m 3 /year. The dam’s planned service age is 50 years old but the measurement results does not support. By comparing the actual sedimentation rate with the reservoir planning data, if there is conformity it is necessary to do maintenance and if there is a faster estimate than the actual plan then it needs to be done sediment handling that occurs.
