All lifestages exhibited declining WUA values at <br />flows higher than the discharge corresponding to the maximum WUA value (Figures 23 <br />and 24). This site had an extremely low suitability of spawning habitat. This is due to a <br />high percentage of large substrate (large cobble-boulder) and high water velocities <br />(maximum measured: 1.52 m/s (4.98 ft/s) at 6.43 m3/s (227 ft3/s)) associated with this <br />high gradient reach. Of all Fryingpan River sites, FPR-HG had the lowest average <br />discharge (4.02 m3/s [142 ft3/s]) at which maximum WUA values occurred. <br />At low flows, pools provide refuge habitat with depths exceeding 0.8 m (2.7 ft) at 1.13 <br />WUA at this site. 7-7 <br />m3/s (40 ft3/s) (Figure 25). However, the average depth in run and riffle cross sections is <br />only 0.24 m (0.8 ft) and average maximum depth is only 0.4 m (1.31 ft) at 1.13 m3/s (40 <br />ft3/s). At low flows riffle and run habitats contain only a small portion of the overall <br />... ..- - <br />i <br />Draft Final Report, Fryingpan and Roaring Fork Rivers February 12, 2003 <br />Miller Ecological Consultants, Inc.
