In order to adopt measures for storing more water in reservoirs, lakes and ponds; toprevent water pollution, protect water sources and extend the service life of thesefacilities, it is important for manager (Municipalities, Directorates of the StateHydraulic Works (DSHW), Irrigation Unions etc.) to know the current topographicconditions and any changes in the storage capacities of these facilities. This studyaimed to identify the updated topographic and bathymetric data required for theefficient management and usage of Altınapa reservoir, changes in surface area andvolume of the facility, and to form a Reservoir Information System (RIS). Twodigital elevation models, from 2009 and 1984, were used to determine changes inthe storage capacity of the reservoir. The calculations indicated that, within this 25-year period, the storage capacity of the reservoir decreased by 12.7% due tosedimentation. A Dam Information System (RIS) was developed from a wide rangeof data sources, including topographic and bathymetric data of the reservoir and itssurrounding area, data on specific features such as plant cover, water qualitycharacteristics (Temperature, Dissolved Oxygen (DO), Secchi Disk Depth (SDD)and pH), geological structure, average water level, water supplied from springs,evaporation value of the reservoir, and precipitation.
