The paper analyzes the modern water management balance of the Republic of Crimea in the context of administrative and territorial units. The possibility of using the ArcGIS 10.4 software package for visualization of spatial statistical data that characterize the water balance is shown. The forecast values of the water balance of the Republic of Crimea for 2030 are given. Maps of the current water management balance for the administrative-territorial units of the Republic of Crimea for the current period and for 2030 based on statistical observations have been constructed. It has been established that the territory of the Republic of Crimea is extremely water-deficient and only in certain administrative-territorial units a positive water balance is observed (Bakhchisarai and Belogorsk regions of the Republic of Crimea, Sudak urban district, Alushta urban district and Yalta urban district). At the same time, according to forecasts, by 2030 it will be possible to significantly reduce the water deficit, but a number of regions of the Republic of Crimea will still have a negative water balance.
