In this study, in order to draw a road map for lake water budget modeling, model calibration was performed with statistical results by modeling in a stream that feeds the lake basin and has flow observation results. The aim was to make a preliminary estimation and evaluation for calibration of the model result to be obtained in streams without flow observation results in the lake basin. The WEAP (“Water Evaluation and Planning” System) model was used for this purpose. With WEAP, Soloz Stream was selected to determine the amount of flow in streams with no flow. Soloz Stream was selected to determine the amount of flow in streams that do not flow with WEAP. Climate data, flow values obtained from Princeton University climate data, and flow observation results from the data obtained by including the spring flows of DSI (General Directorate of State Hydraulic Works) were modeled comparatively. Studies on the hydrology part of the model are limited in the literature, and this study contributes to the literature with a hydrological evaluation. In this context, the total annual water budget was extracted together with the water budget components, and an estimation was made with the model result for the main flow in the stream from the flow continuity curve. As a result of this study, the findings obtained from the modeling research with WEAP indicate that the model results and the observed results are compatible based on statistical calibration parameters. However, the consistent results observed include the source measurements, so the flow results obtained from precipitation alone are not consistent enough, and it is observed that the model gives reasonable results when climate and source flows are modeled together.
