This article presents the results of studies on the comprehensive assessment pertaining to the peculiarities of nutrition, accumulation, transit and discharge of groundwater in the adjacent territory of the Sorbulak reservoir. The information about the waste water storage was presented. The results of the analysis and decryption of satellite images, as well as the results of aerial photography of the territory of the Sorbulak were presented. The results of field route studies of the work area were presented to identify the external manifestations of directional filtration, areas of exits to the daytime surface of groundwater. The results of the calculation of the filtration flow controlled by the Sorbulak storage lake, unloading through the western side of the plateau into the Kurty River, were presented.
