<br />DMC <br /> <br />RM 307 and 311,5. The floodplain within this section is also the <br />most developed along the Green River: mostly cropland and pasture, <br />-Of high biological importance for habitat restoration, <br />-Conclusion: highest priority geographic area for floodplain <br />restoration and protection because of numerous restoration <br />opportunities: because maintenance of floodplain developments is <br />expected to continue: and because of high biological importance, <br /> <br />f, RM,320 to RM 410 (Dinosaur to Flaming Gorge) LOW PRIORITY <br />-Razorbacks: includes spawning and adult areas, <br />-Squawfish: includes high concentration and distribution areas for <br />adults, and nursery areas for young, <br />-Approximately 1.720 acres of potential floodplain habitat: some <br />man-made levees. <br />-Floodplain owned primarily by the NPS, BLM, FWS, USFS. and State of <br />Utah: includes Brown's Park National Wildlife Refuge. and the Yampa <br />confluence at RM 345: some floodplain development has occurred <br />(e,g" levees at Brown's Park), <br />-At present. the temperature of waters released from Flaming Gorge <br />Reservoir creates a thermal barrier in the Green River above the <br />confluence with the ,Yampa, which limits use by endangered fishes, <br />As a result, this section of river is not being considered a <br />priority geographic area for floodplain restoration and protection <br />at this time, Studies are being conducted to explore opportunities <br />for thermal enhancement of waters' released from Flaming Gorge, If <br />the studies conclude that water temperatures can, be managed to make <br />the river habitable, then this area will be targeted for floodplain <br />restoration and protection, <br />-Of low biological importance for floodplain habitat' restoration at <br />this time, <br />-Conclusion: low priority geographic area for floodplain protection <br />at this time because of low water temperatures above the Yampa, <br /> <br />3, Colorado River <br />a, RM -16 to RM 0 (Cataract Canyon) LOW PRIORITY <br />-Razorbacks: larvae have been captured at the inflow to Lake Powell <br />(Sheep Canyon), so they no doubt drift through Cataract Canyon, <br />-Squawfish: area contains adults and young, <br />-Negligible amounts of potential floodplain habitat, <br />-Floodplain owned, managed, and protected by the National Park <br />Service: no floodplain development has occurred or is expected to <br />occur: levees. if any. are natural, <br /> <br />12 <br />
