Density decreasing inside a ground construction has an influence on the gravity obseived on the surface stations. The gravimetric monitoring contained the connection of investigated points on a hydrotechnic object to the outside located reference stations and permanent registration of gravity variations taking into account the solar and lunar tides. The basic problem in the interpretation of the results was the elimination of the variations of water level and its influence on gravity. A special software for this purpose was worked out. The paper presents a comparison of theoretical and observed gravity changes while maximum and minimum water level heights occurred.
