This paper presents the assessment of climate change impacts on some critical water management issues such as reservoir storage and hydroelectric production. Two equilibrium scenarios (UK Meteorological Office High Resolution model, UKHI and Canadian Climate Centre model, CCC) referring to years 2020, 2050 and 2100 and one transient scenario (UK High Resolution Transient output, UKTR) referring to years 2032 and 2080 were applied to represent both ''greenhouse'' warming and induced changes in precipitation and potential evapotranspiration. By using these scenarios, the sensitivity of the risk associated with, the annual hydroelectric energy production of a large multipurpose reservoir in northern Greece has been evaluated under conditions of altered runoff. It is shown that the operational characteristics of the reservoir designed and operated under current climatic conditions are, in general, affected by the climate change scenarios examined. Increases of the risks associated with the annual quantities of energy production have been observed, particularly under the UKHI and the UKTR scenarios. For the UKHI scenario, increases of reservoir storage volumes of up to about 12% and 38% are required in order to maintain at current risk levels the minimum and mean annual energy yields respectively, while for the UKTR scenario the corresponding increases are estimated to be about 25% and 50%.
