Abstract: Based on the system analysis of the long-term information and analytical materials of the RSE «Kazhydromet» on water pollution in the Yesil river basin and the use of the Shannon index and the maximum pollution coefficient V.V. Shabanova made an assessment of water quality by hydrochemical indicators on a spatial and temporal scale in the conditions of anthropogenic activity to identify the causes and consequences of the formation of the hydrochemical regime of water bodies. On the basis of the conducted multivariate assessments and rationing of the water resources of the Yesil River, the directivity and intensity of changes in water quality, that is, their pollution with the main ions (Cl, Na, SO4), biogenic elements (NH4, NO2, NO3) and heavy metals (Cu, Zn) are shown on a spatial-temporal scale which are one of the main environment-forming systems for the life of the population of Central and Northern Kazakhstan. In this case, the maximum pollution coefficient (Knз) in the catchment area of the Yesil River Basin on a time scale from the hydrological station - the village of Turgenevka to the village of Dolamatova are increasing and, by degree of pollution, mainly refers to the contaminated and trophic status of E.S. Shannon - eutrophic, which must be considered when developing environmental protection measures to restore and improve the eco-capacity of water bodies in Central and Northern Kazakhstan
