Figures 21 and 22 show distributions for flows in Reach Two that had a duration of two <br />and four weeks, respectively. Figure 21 shows a noticeable increase in the Action (ALL) results <br />at about 40% exceedance. This was a result of the Action(ALL) ruleset attempting to achieve the <br />18,600 cfs objective. <br />
