<br />At 200 cfs Sevens had double the percent of surface area at intermediate (2.5 to <br />3.5 ft) depths with about 12% of the area (Figure 3, and Figure A3.6). At flows of 50, <br />100 and ISO cfs the percent of area in the depth range of 2. 5 to 3,5 feet was about 10% <br />at Sevens compared to 5% at Duffy. <br /> <br /> 50% <br /> 45"10 <br /> 40% <br />.. 35"10 <br />I!! <br />< <br />'C 30% <br />.. <br />:: <br />.. 25% <br />:!: <br />... <br />c 20% <br />.. <br />'" <br />- <br />.. <br />Do 15% <br /> 10% <br /> 50/. <br /> 0% <br /> 0 1 <br /> <br /> <br />Flow of 200 cfs <br /> <br /> <br />2 <br /> <br />3 <br /> <br />4 <br /> <br />5 <br /> <br />6 <br /> <br />7 <br /> <br />6 <br /> <br />9 <br /> <br />10 <br /> <br />Depth in feet <br /> <br />Figure 3. Percent of wetted area for depths at a flow of 200 cfs for the Duffy <br />and Sevens study sites. <br /> <br />In the depth range between 3.5 to 5.5 ft Sevens and Duffy had similar areas (6%) <br />at 200 cfs (Figure 3 and Figure AJ. 7). However at flows less than 200 efs, area dropped <br />quickly to just below 2% at Sevens but remained at 6% for Duffy (Figure AJ. 7). Sevens <br />had very little area with depths over 5.5 ft (0.1%) at flows of 50, 100 and 150 cfs while <br />Duffy had about 2% at depths over 5.5 feet between SO and 200 efs (Figure AJ.8). This <br />data indicated that even at very low flows, the Duffy station still maintains deep pool <br />habitat, while deep pools are lost at the Sevens station. <br /> <br />18 <br />
