In the thesis is represented the micro-levelling geodetic network of the Hidroelektrarna Moste (Hydroelectric Power Plant Moste), which is spread along the central barrier in the Kavčke Gorge under Žirovnica. The results of the calculations of geodetic network from 1958 to 1986 were represented. The change of two geometric networks and the used instruments. All the data were reprocessed, the observations were levelled, the results of relative and cumulative movements were logically represented in tabular and graphical form. We provided unified geodetic datum while levelling through the entire period. That provided results us continuous insight into network action throughout the period of 28 years. The showed that in majority there were no bigger movements of benchmarks.
