In the design of reclamation systems, there are frequent cases of discontinuous measurements of precipitation. As precipitation can have rather non-uniform temporal and spacial distributions the objective of this paper is to identify the main characteristics of precipitation for the region of Southeastern Srem, to calculate the correlation between the data in the part of the area where the measurements are missing. The precipitation amounts recorded at the study pluviometric stations show a good correlation with the precipitation amounts recorded at the basic meteorological stations both for annual precipitation, and for monthly precipitation. The correlation is the strongest in autumn and winter (up to 0.99), and because of spring and summer storms, often of strong intensity, correlation coefficients are a little lower in these seasons. It should be concluded that there is a very good agreement between the results of: arithmetic mean method - 633.3 mm, Thiessen polygon method - 628.08 mm and isohyetal method - 632.8 mm. This is explained by the fact that the terrain is flat and that the selected stations cover the area uniformly. The missing data can be supplemented based on regression equations.
