<br />trout natural recruitment has been severely restricted since 1991 primarily due to whirling <br />disease factors~ Fingerling size (4 to 5 inch) rainbow trout have been stocked in the fall <br />since 1992 to increase rainbow trout abundance in this section. <br /> <br />Habitat characteristics in this reach range from a stream habitat improvement area <br />completed by the CDOW research section in 1993, to long shallow glides, runs and riffles <br />interspersed with deep pools usually on the outside river bends and an overall large <br />width-to-depth ratio (that is, wide and shallow)4 The habitat improvement area directly <br />downstream from Spinney Mountain Reservoir dam now has a decreased width-to~depth <br />ratio, several constructed willow/gravel barst rock vortex structures, better pool spacing <br />along the stream, and improved bank stabilization. Future habitat improvement projects <br />using similar techniques are scheduled for the remaining river areas downstream from the <br />1993 project sitef <br /> <br />CDOW fishery management objectives include maintaining and enhancing wild brown <br />trout and rainbow trout populations~ Supplemental stocking with 4 to S-inch rainbow <br />trout in the fall to increase rainbow trout recruitment will continue as necessary~ <br />Management regulations include Gold Medal Water status, flies and lures only, catch and <br />release for all fish species in this entire segment~ <br /> <br />3. Elel'en Mile to Cheesman Reservoir <br /> <br />The primary sportfish species managed in this reach are brown trout and rainbow trout. <br />Northern pike, yellow perch, cutthroat trout, and kokanee salmon are periodically <br />sampled downstream from Eleven Mile Reservoir (where they are part of the reservoir <br />fishery management program); however, these species are not used to sustain riverine <br />fishery management goals4 Non-sportfish species include western white sucker, longnose <br />sucker, and creek chub (all three are native to the South Platte drainage)4 Rainbow and <br />brown trout are self-sustaining throughout the entire reach4 Catchable-size rainbow trout <br />(average length 10 inches) are supplementally stocked from Springer Gulch bridge <br />downstream to the water diversion structure at the mouth of Eleven Mile Canyon and in <br />the Happy Meadows campground stretch to support higher angling pressure typically <br />found in these areas. <br /> <br />Habitat characteristics in Eleven Mile Canyon range from high gradient, boulder cascades <br />and rapids to long shallow riffles, runs and glides. Erosion and depositional areas exist in <br />many of the low gradient areas, because of unconsolidated banks heavy recreational use <br />and increased road use~ Riverine habitat below the canyon mouth is channelized around <br />Lake George, then it is primarily wide and shallow with little riparian cover downstream <br />from Highway 24 to the Happy Meadows campground stretch. Riparian habitat <br />characteristics improve through the Happy Meadows campground area downstream <br />through Wildcat Canyon, although channel morphology tends to remain wide and shallow <br />except where canyon geological features decrease width-to-depth ratios in some areas <br />down to Cheesman Reservoir. Further details regarding riverine habitat characteristics <br />can be found in the USFS Wild and Scenic River Study and Draft LEIS. <br /> <br />N :\Supply\ Waage\wildscen\attachb.doc <br /> <br />B...18 <br />
