<br />23 <br />included in the figure, The historic flows show how Flaming Gorge Dam operations prior to the <br />1992 Biological Opinion, effected the distribution of flows in Reach One during the base flow <br />period, Releases prior to 1992 were elevated above natural levels to produce power, The <br />historic unregulated flows for the same period indicate how the distribution of flows in Reach <br />One might have been if Flaming Gorge Dam did not regulate the flow of the river. <br /> <br />FIGURE 19 Exceedance Percenta e Flows for Reach One Flows Durin Base Flow Period <br /> <br />Base Flows - Reach One <br />August through Febuary <br /> <br />5000 <br /> <br />~ <br />.:l <br />~ <br />" <br />o <br />ti: <br />2000 <br /> <br /> <br />-e- No Action <br />+- All-I <br />All <br />-{I- Historical (71-91) <br />"*'" FGUureg(71-91) <br /> <br />3000 <br /> <br />woo <br /> <br />9J% <br /> <br />20% <br /> <br />40% 60% <br />Percentage Exceedance <br /> <br />80% <br /> <br />100% <br /> <br />Reach Two Spring Peak Release Results <br /> <br />The model accounts for flows in Reach Two by adding the flows from the Yampa River <br />to the flows from Reach One, The estimated flows at all points along Reach Two were assumed <br />to be equal to the release rate from Flaming Gorge Dam plus the flows on the Yampa River, The <br />Green River model lagged Flaming Gorge Dam releases by one day to account for travel time <br />through Reach One, <br />
