The main indicators of the salt composition of the water bodies of the Khanty-Mansiysk region in the dynamics of the seasons of the year are examined. The relevance of the study is caused by the fact that water objects of the region are of great importance in fishery management, which entails the need for constant monitoring. Carrying out various works on such reservoirs has a negative impact on the ecology of aquatic organisms and leads to a decrease in the natural productivity of water bodies. An assessment of the state of watercourses in the licensed area of the Middle Ob River oil field was carried out. It is shown that the natural background of the content of individual indicators of salt composition exceeds the normative values of MPCspp (total iron, manganese) many times over, while the presence of other ingredients has a very low threshold for their content (chlorides, nitrates, sulfates).
