Figures 16 and 17 show how the duration of the release peak was affected by the
Action(ALL and ALL-I) and No Action rulesets. The distribution of Reach One flows that were
exceeded for a duration of two weeks is presented in Figure 16 while Figure 17 shows the
distribution of Reach One flows that were exceeded for four weeks. Distributions for all three
model runs are presented while the historic values that occurred during the period from 1971 to
1991 are also presented in these figures.
