study and can thus not be safely determined at this point. Diminishing reservoir inflow certainly has a negative impact on safe yield, especially if all safe withdrawal is already committed in an existing water delivery contract. The two most prominent adaptation strategies pursued by the dam owner/operator include close monitoring and modelling of the reservoirs short- and long-term water balance combined with exploring additional infrastructural investments aimed at increasing the catchment area and thus reservoir inflow.
