Water management and environmental problems of the Ob basin: current state and forecast until 2030

The modern system of water resource management is based on the principles of best available techniques (BAT) in economy and other activities. It implies rational use of natural resources, their protection from harmful effects, creation of the integrated system for the natural resource–economy system. Shortcomings of the economic regulation in water management can be overcome by intensifying the transition to technological regulation via BAT. At present, the first stage of the implementing this system in Russia is completed in the field of environmental protection to minimize the negative environmental impact, including water resource management. The paper analyzes practical activities of water users to assess its effectiveness for the years 2019–2021 on the example of the Tom river from Kemerovo to its mouth in the Tomsk region. Positive trends in water quality are described. The development of the water-ecological situation in the study area is predicted. The obtained results will allow optimizing the water use in the region.

The results of estimation of the number of generations of the Lower Ob broad whitefish are presented. On the basis of data on the number of larvae descending from spawning grounds, obtained in 1981-2023 on the main spawning rivers, conclusions are drawn about the current demographic situation in the Lower Ob broad whitefish population, about the influence of anthropogenic factors and water content of the Ob floodplain on reproduction. It was established that the decisive importance in the reproduction of the broad whitefish in the 80s and 90s belonged to the Severnaya Sosva River. In recent years, there has been an increase in the contribution of the more northern rivers Voykar and Sob. The decreasing role of the Severnaya Sosva River is connected both with climate warming in the region and with increased removal of producers by fishing, including for fish breeding needs. The reproduction of the broad whitefish population is weakly dependent on the water availability in the Lower Ob floodplain. In order to restore its numbers, it is necessary to significantly change the system of protection of spawning herds and organise protected areas in the Khulga River basin. Artificial reproduction of the broad whitefish is not required.
