ABSTRACT
The article presents an analysis of maximum annual water stages on the Great Prespa Lake at Gauge Station Stenje. To better scientific approach was necessary to obtain 60 hydrologic years of maximum annual water levels in cm (1951-2010). The best fitting distribution was Pearson distribution type 3 according to Kolmogorov-Smirnov test, after defining the low threshold outlier in annual maximum lake level time series. For analyzing of maximum annual water levels was taken General frequency analysis with Stage frequency analysis in analytical (Pearson type III distribution) and graphical option (User defined graphical curve) in the software HEC-SSP 2.0. According to natural pluvial conditions, the Prespa Lake is one of the biggest fresh water objects in the Balkan Peninsula, so its flood regime importance for nature and humanity is great.

Keywords: Maximum annual stage, probability distribution, tests, return period.
