This article analyzes the impact of climate in the conditions of industrial development on the flow and ecological
condition of the Kazakhstan part of the river Yertis on the territory of East Kazakhstan (EKR), Abay and Pavlodar
regions. The research is based on the analysis of data from the meteorological base of the Republican State
Enterprise (RSE) «Kazhydromet» for the period from 2019 to 2023. The relationship between air temperature,
precipitation and the flow of the river Yertis is shown. The results of the analysis showed that for the last 5 years
there is a decrease in the flow of the river Yertis from China and the flow inflow to the territory of Russia. The
water quality of the Irtysh River was assessed in the context of administrative regions. Water quality was assessed
by 18 hydrochemical indicators in 14 sites on the border with the People’s Republic of China in the area of Boran
village; above and below major cities - Ust-Kamenogorsk, Semey and Pavlodar; Priirtyshskoye village on the
border with the Russian Federation. The results of the assessment of the environmental condition of the Yertis
River showed that the most polluted is the section of the river on the territory of East-Kazakhstan region.
