Short summary
We assessed the effects of different modes of operating reservoir on its ability to moderate water shortage impacts caused by climate change. The operating rule approach was enhanced by hedging using multiple zones and monthly rationing ratios for curtailment of water release. The results showed that basic hedging with single zone and constant rationing ratio caused significant reduction in water shortage during severe droughts. More complex operation modes produced only modest improvement.
