<br />'7 <br /> <br />The North Fork River moves little if any >050 bed material except at bankful heights and higher. <br />Accordling to the testimony of river-side landowners, the river does not get destnlctive or highly erosive <br />until higher flow levels. The highly destructive flow levels are approximately 5500 CFS or greater. There <br />are however special circumstances that could cause the river to erode large sections of river at lower flow <br />levels; for example a lodged tree in the current. <br /> <br />8000 <br />7000 <br />6000 <br />5000 <br />4000 <br />3000 <br />2000 <br />1000 <br />o <br /> <br />1)..1).. rV <br /> <br /> <br />[i] <br /> <br />4- bol).. ~ ,:>1).. 4'- col).. rd- ,\1)..

The Standard Deviation of the mean is <br />1375.36 CFS, The flows have reached 5500 CFS six times in this time frame, which is 7.8 percent of the <br />time. Approximately every six years. <br />These numbers do not take into consideration Paonia Reservoir because Paonia Reservoir does not <br />seem to c~ffect the peak flows. The reservoir fills up before large water flows occur. <br /> <br />,/ <br />
