CHAPTER FIVE-ELIGIBLE RIVER SEGMENTS: LOWER GLINNISON <br /> II - RIVER SEGMENT: ROUBIDEAU CREEK, SEGMENT 2 <br /> HYDROLOGIC UNIT: Lower Gunnison <br /> Description: Roubideau Creek is a perennial tributary of the Gunnison River that drains from the <br /> east side of the Uncompahgre Plateau. High flows typically occur during spring snowmelt and from <br /> runoff generated by occasional summer thunderstorm activity. The upper terminus of this segment <br /> is the north boundary of Camelback WSA, while the lower terminus is along the boundary of lands <br /> managed by the State of Colorado, approximately three miles upstream from the Gunnison River <br /> confluence. <br /> Lower Terminus - Latitude: 38° 42' 10.67" N; Longitude: 108° 8' 49.95" W <br /> Upper Terminus- Latitude: 38° 38' 9.10" N; Longitude: 108° I I' 23.20" W <br /> River Segment Ownership (in Miles): <br /> f y#rif "9`�x� 3g"� .•:ti WPq'P -i; s're Oi ,rom- -wp vivaz - <br /> 3.45 4.14 7.59 45.5% <br /> Land Ownership within One-Half Mile Wide Corridor(in Acres): • <br /> Y§'y�. 2'3�'Y£�Fe:14- rm `3''�' i s��a 1,"l�"tx�vxr�" rY ✓; �;yq.},.v"h 3 <br /> °°1rt" " 'Zs-. �' S�'.;R 3' R. 0 ; � }F.[? { ; �0� 135� <br /> 'k i - Y a;,.

This species has been <br /> petitioned for listing and is currently under status review by the FWS. A twelve-month finding <br /> is pending which will determine whether listing of this species throughout all or a significant <br /> portion of its range may be warranted. This section of Roubideau Creek is also regionally <br /> important habitat for desert bighorn sheep (Ovis canadensis). The creek is used extensively as a <br /> water source by this species, while the cliffs above are used for lambing. <br /> 2) Vegetation - This section of Roubideau Creek contains areas of Fremont cottonwood/ <br /> skunkbush sumac riparian woodland (Populus deltoides spp. wislizenii/Rhus trilobata), which is <br /> classified as globally imperiled (G2). The segment is included within the CNHP-designated <br /> Roubideau Creek Potential Conservation Area. <br /> Preliminary Classification: Scenic <br /> Rationale - Roads or trails parallel the creek along this entire segment. There is an unhardened <br /> road ford near the upper terminus and a county road bridge in the lower section. There are <br /> water diversions along this river segment. A large diversion near the headwaters significantly <br /> reduces the flow in this segment during irrigation season. <br /> JUNE 201 0 BLM UNCOMPAHGRE FIELD OFFICE,COLORADO T"y ;"z'.` 49 <br /> Final Wild and Scenic River Eligibility Report <br />
