This paper presents the results of the classification and zoning of the evapotranspiration fluxes for the growing season ETaw in the Marksovsky district of the Saratov region for the growing seasons of 2003-2017. The calculations for these types of spatial analysis were carried out in the ArcGIS Pro 2.8 software environment using the previously obtained two spatial arrays ETaw. To classify ETaw flows by land use types, we used raster datasets obtained at IIASA (International Institute for Applied Systems Analysis) for the territory of Russia as a result of processing and analyzing space monitoring data. Analysis of the classification results for the study area revealed a significant difference in ETaw flows in areas occupied by different types of land use. For zoning ETaw flows by distance from the left bank of the Volga River, the boundaries of seven zones were built at distances from its edge: 0-5 km; 5-10 km; 10-20 km; 20-30 km; 30-40 km; 40-50 km; 50-60 km. For the territories located within the indicated zones, the filtration of two ETaw flows was carried out, which revealed a decrease in their values as they moved away from the left bank of the Volga River
