Figure 4 -8 shows the 10th, 50th and 75th percentile elevations at Powell. Both the
10th and 50th percentile are unaffected by the extension of the ISG. Beginning in
2017 there is a slight decrease at the 75th percentile from extending the ISG. This
decrease is minor with a maximum 5 ft difference compared to the strategies
without the ISG extended.
