This article analyzes the problem of the state of the water bodies in Ishim by anthropogenic pressures. The study shows that the water reservoirs are negatively influenced by the economic activities of the population. The author defines their main directions: industrial wastewater discharge to the city water bodies, construction and operation of engineering constructions, activity in the private sector. To assess the state of the water bodies the author uses the results of the visual assessment of the state of the riverbeds and their coastal zone, the organoleptic water indicators (turbidity, color and smell), the analysis of the hydrobiological studies (determination of the degree of saprobity of the water bodies as indicators ciliated infusoria). The study showed the satisfactory condition of all the water reservoirs and the non-critical impact. As the enterprises for light manufacturing and food industries in Ishim are not sources of chemical, organic and other pollution the visual assessment didn't reveal significant deformations of the riverbeds and any changes in the coastal zone. The impact of the private sector is local and not the significant cause of organic pollution.
