Monitoring condition of hydrotechnical structures conducted to ensure the management of the rational and safe operation of the waterworks. Based on the results of regular interconnected control observations of the state of the GTS, a database of observations is compiled. On its basis, analysis and evaluation of the forecast of the development of negative processes at the facility and development of recommendations for their overcoming and elimination of identified violations are carried out; prevention of emergency situations; creation of conditions for safe operation. Monitoring safety GTS carried out on the example of hydrotechnical structures of the blocking regulatory structure of the Aleksandrovogai reservoir in the Saratov region. The main quantitative and qualitative indicators and their criteria values are given. It is recommended that during operation, visual observations be carried out daily, instrumental observations - at least 1 time in 3 years, in addition to this, at least once every two weeks to inspect the hydraulic structures with the results recorded in the appropriate journal. Systematic visual observations should be supplemented by pre-flood and post-flood inspections of structures, as well as unscheduled inspections carried out after extreme events accompanied by damage to structures. Particular attention should be paid to observing the filtration regime in the body and base of the dam, the state of fastening of the inlet and outlet heads, closures and pipelines of the outlet structure.
