In the context of global climate change and increasing anthropogenic impact, the study of hydrological and geostructural transformations of artificial reservoirs is of particular importance. This article presents a comprehensive analysis of changes in the Koskorgan reservoir, located in the arid region of southern Kazakhstan, which performs important functions of water supply and irrigation of agricultural lands. The research is based on the application of modern methods of remote sensing, geoinformation modeling, field hydrological observations and engineering and geological surveys for the period from 1990 to 2024. The results show a steady trend of reducing the reservoirs mirror area (to 12.4% over 20 years) and lowering the water level (by 1.3 m), which is associated with climatic factors such as precipitation deficiency and high evaporation, as well as increased filtration losses. Geostructural analysis revealed the presence of active tectonic faults in the southeastern part of the reservoir, affecting hydrodynamics, uneven expansion of the eastern section and increased permeability of sediments, which complicates the maintenance of a stable water balance. Hydrochemical data indicate seasonal dynamics of water mineralization and hardness due to climatic conditions and anthropogenic impact, including local pollution and intensive water use. Comparison with similar reservoirs in Central Asia confirms the influence of a complex of climatic and man-made factors on the transformation of small and medium-sized reservoirs. The scientific novelty of the work lies in the integration of multi-scale analysis methods, which makes it possible to identify the spatial and temporal dynamics of changes and provides a basis for developing adaptation strategies for sustainable water resources management. Special attention is paid to the control of filtration leaks and monitoring of geostructural processes to preserve the environmental and socio-economic sustainability of the region.
