losses and seepage in the GERD reservoir, which will be evident in years of low
Blue Nile flows.
Figure 14 shows a set of possible scenarios for the HAD reservoir end-of-year
storage in the 105 years following the completion of the GERD, starting with 10-year
average flows of 50 BCM during “first filling,” compared to the baseline scenario
without the presence of the GERD. It is clear from all the scenarios presented that
HAD storage falls under the dead storage level of 31 BCM (i.e., below the level at
which turbines can operate) due to the expected cumulative effect of evaporation
