The results of calculation of key parameters for free surface curve for water stream at Svisloch's cascade reservoirs considering maximum stream flow through water overflow are presented. Calculation scheme for free area curve's parameters evaluation is shown. Comparative analysis of the hydro systems' level regimes is made. Assessment of interposition of adjacent hydro units is made. The following conclusion is made: the most part of the reservoirs included into the cascade are located within an impact area of backwater curve. The results of the research show that consequences of potential hydrodynamic failures are even more serious, if a free streambed area between water reservoirs is available, than if such failures happened in backwater due to water stream speed increase in such area.
