a spatio-temporal analysis of the main indicators of the water quality of the Hodza River, the change in time of water quality along the river under the conditions of anthropogenic impact is carried out. In general, the waters of the river are characterized as “extremely dirty”. Among the pollutants, iron and ammonium nitrogen compounds absolutely prevail. There is a tendency to some improvement in the quality of river waters downstream. In the upper reaches, the COD is 1.7 and 2.5 times higher than in the middle and upper reaches; BOD – 1.6 and 2.3 times, respectively.
