This article describes the results of the implementation of new permanent monitoring systems in relation to long-term operation of hydraulic structures. At present, more than 80% of the hydraulic structures in the south of Russia have fulfilled most of the standard operating life. Residual resource of hydraulic structures allows to establish a safe period of their operation without restrictions or with restrictions, or to make a decision on repair or liquidation of hydraulic structures and parts of its elements. Existing methods of inspection of hydraulic structures are aimed at assessing the overall suitability of structural support structures for further operation. During the surveys a number of questions arose regarding the nature of the detection of damages and defects, as well as the forecasting of the technical condition for a certain period of time. The purpose of the multifactor survey of hydraulic structures is to assess the actual technical condition, the main equipment, determine the remaining resource of their elements, and establish safety deficiencies to assess the possibility of continuing operation beyond the designated (or 25-year) service life. The results of the multifactor survey are the basis for preparing the facility for the extension of the service life. In the period of low water in the upper reaches and the lower reaches of the Volga and on the Don, below the Tsimlyansk hydroelectric station, ship companies experience the problem of missing ships at full load due to inadequate depths. The physico-geographical characteristics of the Lower Don are described, the history of its sluicing, it is proposed to use flexible water-lifting dams, which at low water promote the rise of the water level in navigable rivers, and during the high-water period they fit into the flow channel of the channel section.
