During the construction of small hydropower plant in Markovci, an elevation point – the benchmark, that allowed the transfer of height on spillways, was destroyed. The thesis presents the process of stabilization and determination of definite heights of the new benchmarks. We performed a survey of geometric levelling with a reference to the two baseline benchmark R36 and R37 to determine the
definite height of two newly stabilized benchmarks and a re-measurement of the benchmarks on spillways. A height comparison was made of the benchmarks on the spillways with the last measurement in 2011 and an analysis of results.
