Taking into consideration the strategic importance of barrages and accumulation lakes, watching the behavior of the hydrotechnical construction is an essential activity throughout its entire life. A very important component of this watching is represented by tracing the shiftings of the bench marks, set for this reason, both horizontally and vertically. As a particular case there will be presented the Valea de Pesti Barrage, which was watched from the point of view of the horizontal and vertical shiftings, since its construction until present, obtaining shifting graphics for each bench mark, graphics from which an anticipation of this hydrotechnic objective behavior can be done.
