The aim of the work is to estimate the influence of filtrating water on the rise of ground water level and determine the extent of possible flooding of settlements and economic objects adjacent to water reservoirs. To calculate the head of ground water, the method of N. N. Verigin was used. This method was developed on the basis of linearization of differential equation of Bussineska. The given calculating method was carried out by software Mathcad. The calculations of ground water head were made by the example of rivers Tsna and Lesnoy Tambov near Tambov reservoir and Kotovsk city. Comparing the calculating data and results of piezometric monitoring before and after reservoir filling we conclude the adequacy of the given calculating method on field monitoring data.

The relative error in calculations doesn’t exceed 4 % what is within the limits of accuracy for ground water measuring in monitoring bores. Calculations at different water levels in reservoir (from 124 to 128 m) enable to conclude that the output of ground waters to the surface in Kotovsk city will not occur at modern operation water levels in reservoir. Increasing of reservoir water level up to 126-128 m will provide the gradual increasing of ground water levels at the whole territory of Kotovsk, including the south part of the city. The predictive calculations for 100 year period show that the rising of ground water level on Yuzhnaya Street up to 120.56 m at 126 m and up to 120.95 m at 128 m will provide the output of ground water to the surface by a layer of 25 to 90 cm.
