Abstract: It will be of great use to know the regime and tendency of changes in lake water levels in Turkey for both current and future studies, which are of importance for accurate assumptions in future. Therefore, annual Turkish lake levels are analyzed to document some of their variability characteristics in this study. Annual cycles are first computed from monthly means at each individual lake station. The amplitudes and phases of the first harmonics, fitted to monthly lake level means, are displayed in vectorial fashion. Secondly a non-parametric trend test (the Mann-Kendall) is applied to detect possible linear trends in the lake levels. Results of this study are evaluated by considering the impacts of precipitation regime.
